|Aileron bell crank fix
A member recently found that the bushing around the aileron control horn pivot bolt was turning. It wore an elongated hole right into the aileron bell crank bracket! This could have been a real disaster. Here is what they did to fix it:
"You will have to disconnect the aileron to get a good look at the bellcrank attach bolt. All four of our holes were elongated. The bushing seized in the bell crank and the thru bolt started turning (with each movement of the aileron) in the hole elongating the hole. The wing has to be opened to get the assembly out. Could not remove the seized bushing with things installed. ...the corner of the wing gets opened up. I think the Twin-bee has an extended wing, so there was a skin joint we could work with, opened up an "L" shaped corner. I would suggest folks make sure this area gets lubed, once the bushing seizes in the bell crank its down hill. You should not see the nut turning when the ailerons are moved. This is how we repaired the aileron brackets (right photo)....doublers on the top and bottom of each leg (4places). Used .063 on the outside and .040 on the inside."
(Ed note: This is great information and I would recommend checking these out now and at every annual inspection. This aileron bracket is bolted to the aft side of the trailing edge spar with four bolts. Trouble is you can't get it out through the lightening holes in the spar so the wing has to be drilled apart in strategic locations. Lubrication is the key! I spray those things at least every annual with LPS-2. Spray them until they start dripping down the trailing edge! S.M.)
|Tail Wheel Donuts and Shims
Member Ken Deyo has a great way of making the Tail Wheel donuts and spacers. You guys never cease to amaze me! You can read his instructions here. If you need replacement instructions download them here.
Thanks Ken! Good job!
|Bow Door Hold-Open Rods
There are probably as many Bow Door hold-open options as there are Seabees. Send me an email with your installation and I will list it here. Mine is listed below:
It is a very basic design but has worked for 15 years so far with no adverse effects. It is simply a 7/16" diameter rod bent carefully to the Bow Door curve with a universal type joint on the top end and a ball joint link on the free end of the rod (available at McMaster Carr here). The socket end is screwed into a stud that is riveted into the rod. A 1/16" stainless steel cable is attached under the ball on the door frame and under the universal joint on the door side of the rod.
This is Simuflight's version. You must contact Scott Henderson at Simuflight for this one.
Notice the clip in the upper right hand side to secure the bow door rod. Good idea.

Have you ever needed to work on the engine or propeller and tired of using an unstable ladder or standing on the Seabee hull? Try making a New and improved Bridge Stand! Inspired by Service News No. 4, page 4, I went to work to design a more up-to-date Bridge Stand for the Seabee. Using 'Architectual Aluminum' (1/8" wall) the stand is very solid and will easily support two men on the steps. I have had the propeller resting on top with two men on the steps! It is easily removable in one piece as opposed to the three piece Republic Bridge Stand. It weighs about 25 pounds!
Wheels were added to one side of the Bridge to facilitate removal before flight. 1/2" plywood was used as a top and secured with self tapping screws. Handles were added for rotating the stand up and over the Seabee deck. Foam pipe insulation was used on ALL interior parts of the bridge that would be a potential 'scratch maker'. The steps are reinforced with aluminum angle under each end of each step and two rubber bumpers are on the bottom of each leg.
The photographs below illustrate the geometry of the Bridge Stand. Here are the drawing and building notes. E-mail Steve if you have any questions.
|Easy to make Hydraulic Powerpac stand
After working on my hydraulic powerpac a few times, I knew there was a better way to support the pump and prevent the inevitable mess of hydraulic fluid all over my workbench. It is simply a gallon tin can with the side cut out and an aluminum frame that sits on the edges of the tin can. It is very sturdy and allows for testing the pump functions. I also use the tin can for washing parts. See the photos below for details:
|Check your gas for Alcohol
This is an article submitted by former member Don Booth to the Seabee Club years ago. A simple way to see how much alcohol is in your gas.
Do-it-yourself Alcohol Percentage Detection (PDF file)
|Jack plate for Axles
New member Greg Wicker from South Carolina has made a simple Jack Plate for changing tires or working on the bearings. It weighs about a pound and can easily be put in the baggage compartment for those long-range trips. Greg says, "Don't forget to chock the other wheel and the tail wheel before jacking the Seabee." The Jack Plate can be used from either side of the axle. A bottle jack is all that is needed to jack up one side of the Seabee. Thanks Greg!
Member Herb Sherwin on "one float strut missing" (and a towbar)...
"I wanted to pass on a recent modification I made to my bee to prevent the problem that the Lake Tahoe bee had when it lost a wing float. Walmart has a water toy that some call a noodle that's made of closed cell foam that is about 56" long by 3" diameter with a 1" hole that runs the length of the tube. It weighs 5 oz. and according to my calculation provides 12.7 lbs. of buoyancy. I put 5 tubes in each wing tip by putting 3 in each droop tip (two whole one and one cut in half with both pieces in the tip) and two in each wing folded in half between the two outermost ribs and the front and next trailing spar. This should provide over 60 pounds of floatation with a moment arm that should help keep the wing from going under. I know "no engineering approval" but I am willing to chance it. I hope to perform an engineering test by taking off a float and letting the wing rest in the water and videoing the results. I will send the video if it turns out ok.
I don't know how other bee folks do for a tow bar but I designed one many years ago that works for me. If this is an item of interest, I will provide details."
(Ed Note: Thanks Herb! If we can prevent just one of these disasters it would all be worth the effort. Herb says Walmart has the "noodles" for a buck a piece.)
|Donut removal tool...
Member Tom Hoag uses a common tool to remove those stubborn tail wheel donuts and spacers. A cotter pin removal tool, available at most hardware or Automotive shops, works well to get the donuts out. You may have to get them out one at a time. After years of shock absorbing the donuts "lock" themselves into the tail wheel tube. Some kind of tool is a must to get them out. Thanks Tom!
|Make a hull stand...
Member Pete Norman has forwarded the following hull stand. It appears to be very solid and will allow you to do just about anything on your Seabee! There are two PDF files you need to download; Bill of Materials and the Plans. It looks like a day of welding is all it takes to get these done (maybe I'm optimistic). This would be a good first time welding project, with proper supervision of course. Also, as you will see below, it makes a great static display at airshows. Pete says, "Most people didn't know what it was!". Thanks Pete (and Bruce Hinds) for the fine addtion to the "Tips and Tricks" page.

|Make some hull stands...
This tip is a modification of the Hull Stands seen in one of the Republic Service Letters. The late Seabee owner Marty Bennett changed the plans slightly to acccommodate the slightly different hull shape. Below is a sketch I made of Marty Bennett's design. You will most likely have to change your Hull Stands slightly to fit your hull. If you want to see the Republic Service News No. 3 version click here (see page 2 and 3).
Click on the photos above for full size view. Note: The wheels on the stands are optional and locking wheel brakes for the hull stands are highly recommended. Note the liberal use of shag carpet for padding between the hull and the wooden frame.
|Picking up a passenger on the water...
This tip comes from Henry Ruzakowski (thanks Henry!): If you ever need to pick someone up out of the water when away from shore, lower your landing gear and step on the brakes! Then have them step onto the right main gear and enter the Seabee normally (wheel-spray rail-cabin floor). The only caution is to get ready to shut the engine down as you approach the bobbing passenger if they are not intimately familiar with the Seabee. If they miss the Seabee as it passes, they could be in the propeller arc as the Seabee goes cruising by. Use caution!
|Put a plug in it!
I know that most of you probably have your own way of keeping track of the Hull Plugs but here is my idea. I use an labeled "Altoids" can and keep it on the floor in front of the pilot's seat as a reminder to put them in before EVERY flight.
There is other stuff in the can as well. The contents are:
9 - Hull Plugs (two spares)
1 - 3/16" Allen Wrench (for the hull plugs)
1 - Schrader valve extension for th tail wheel tire
1 - Trim tab locking set (2 washers and a bolt and self-locking nut)
1 - 90 degree nylon elbow (used for the required IFR static check every two years. Yours may differ.)
2 - Landing gear clevis forks with clevis bolt and castle nut. (This can break if you hit something in the water while the gear is in transit thus causing the gear to become useless!)
1 - Circuit breaker collar (I never used it)
1 - ELT test light for the required test every year (Yours may differ.)
1 - Large washer. I forgot what that was used for but I kept it in the box anyway.
|Make a Maintenance Board...
I made this Maintenance Board after the first month of Seabee ownership 14 years ago!. It will tell you at a glance what maintenance issue is due next. I also included the recurring AD's and ELT battery replacement date. I also included the manditory VOR check and NAV data for IFR requirements. The board is an "Office Depot" dry erase board approximately 3 feet by 4 feet. The lines are made from florist tape (cheap!). The letter are 1 inch vinyl letters available at Office Depot or any other office supply. It hangs on the wall with two provided loops on the top. Two nails in the wall secure it. It is easy to remove from the wall for updating.
Use only the dry erase markers. DO NOT USE PERMANENT MARKER; it doesn't come off very easily. I used red markers for the "next" maintenance event. Black for everything else. Obviousy you can modify yours to fit your needs. This really beats having to look in the logbooks every time something needs to be done.
Hint: draw it out on paper first, then count all the letters you will need. This will determine how many sheets of vinyl letters you will need. The florist tape is available at any craft supply store. I think I bought five rolls (I had a bunch left over). Total cost? About $50. I found it well worth the investment.

Replacing your battery?...(Member Ken Thompson has the answer)
If you don't already know, the installation of a car battery in a Bee is considered a minor alteration--log book entry.
Ref.--Mike Becker/Bill Kunder of the Reno, Nevada FSDO.
It just has to fall within the weights of the certificated batteries.
(Ed note: I have used the Gelcell Marine battery from Westmarine for years. It won't leak and is very powerful.-Steve)
|Check your Electrol Powerpac suction screen!...
(click on image for larger view)
A recent anomaly has reared its ugly head! At a recent splash-in, I landed on the water (full flaps and gear up) and proceeded to try to bring the flaps up and the Electrol Powerpac (manual hydraulic pump) didn't work! I tried the gear and it didn't work either. The electric pump was useless as well. The manual pump handle didn't have the resistance when pumping that it normally had. It felt as if there was no hydraulic fluid in the reservoir (there was). After checking for leaks and determining that none were evident, I tried the flaps and the gear again and it worked! After a fun day of splashing-in I returned home (2 miles away, fortunately) and the flaps and the gear would not work again. What the?? The pump seemed to work intermittently at best and finally I was able to get the flaps up and the gear down. Once in the hangar I proceeded to tear into the "monster". No leaks, no loose fittings, full of hydraulic fluid. What the heck was going on? I then proceeded to call the hydraulic expert, Richie Brumm, and he mentioned that in the past some people were experiencing a check valve failure. The check valve is located inside the reservoir at the rear portion of the pump body base. This check valve allows the fluid to move in both directions with the manul pump. If it has failed or has "popped out" the result is exactly what I was experiencing; no pump pressure either with the manual pump handle or the electric pump. Richie has a fix for this. He puts a cap over the inlet screen with a hole in the center so the fluid can pass through but the check valve cannot pop out because two screws hold the cap intact. Call Richie for details or if you want him to fix yours.
Richie passed along a story of a Seabee owner that had called him on the phone from the airplane. WIth the Franklin engine screeming in the background the Seabee owner was relaying the same situation I had just encountered. He was in considerably worse shape, however, inflight and NO hydraulics. The check valve circlip had popped out disabling the hydraulic system. Richie kept him on the phone while explaining the procedure for slowing the Seabee way down, about 65 MPH, and grabbing the gear with a boat hook (a long , looped rope would work). Pulling the gear forward with the boat hook to the "clunk" detent and landing uneventfully. (Keep your seatbelt on when doing this!!) The tailwheel wasn't down but this caused minor damage. A little tail wheel damage is a small price to pay for sage advice.
My problem was a little bit different however. After removing the reservoir, I noticed that my pump did, in fact, have Richie's modification and the check valve was intact. What! What the heck! Everything looked fine until I took the "Richie cap" off and took the small mesh screen out and looked at it under a magnifying glass. I almost fell down at what I saw. It looked as if someone (not me) had "painted" varnish over the screen! There was also a small amount of fuzz blocking the screen. Evidently, in my splash-in situation, the blockage was not completely covering the screen so after a few minutes of sitting, the hydraulic fluid would seep its way into the pump and the flaps and gear would work fine for one cycle each. After thoroughly cleaning the screen, filling the reservoir and bleeding the system everything works fine. In fact, the symtoms of a failed hydraulic system had been so incidious that I hadn't noticed the gradual slowing down of the systems until I cleaned that darn screen! It is faster and more reliable now than it has ever been.
PROCEDURE: If you don't feel comfortable working on the powerpac, call Richie Brumm or get your trusty mechanic to check it out. Extreme care must be used when removing the screen as it is a fine mesh and VERY fragile.You can do this check without opening the system. Just remove the fluid from the reservoir (I suck it out with a suction gun through the reservoir center hold-down bolt. Kind of like a grease gun that sucks). Remove the center reservior bolt and remove the reservoir. You will have to spread the control cables apart above the reservoir but very little strain is required. Once the reservoir is removed, remove the "Richie cap" or circlip (original) and with a needle or a pair of fine tweezers, carefully remove the screen. There is a check ball under it so be very careful not to get any foreign objects in there. Clean the screen and replace everything. I did a retraction test ten times just to be sure everything was working right. Replace the hydraulic fluid with NEW fluid. Never reuse hydraulic fluid especially when you have had a hydraulic problem. I change my reservoir fluid every annual ispection. Safe flying to you.
|Trailing Edge Bumpers...
Have you ever cut your head on the trailing edge or the hinge supports of your Seabee? This quick and easy fix will save your head or more importantly, the head of your friends or visitors to your hangar. They are made from foam tubes available at Wal-Mart or other department stores under the name "Wacky Noodles" or "Crazy Noodles". Kids use them in the pool or lake as floatation or just to hit each other without harm. You will need about 10 or 12 of them to cover all the trailing edges. I split the tubes length-wise so they can be pushed onto the trailing edge of all the surfaces. I use smaller ones on the aileron and flap hinge supports. The trailing edge of the elevator bumpers will need to be modified for the trim linkage. These moodifications are made easily with a razor blade or sharp knife.
These have saved my head more than a few times. They also prevent most "hangar rash" that occurs when foreign objects are weilded hap-hazardly in the proximity of the airplane (yikes!).
I would like to take credit for these, but I can't. The late, former member, Jim Poel was the one who "invented" them. Thanks Jim!
|Tail boom block...
Use this on your jack pad to prevent the unthinkable. The notch fits into the keel strip just forward of the tail wheel. Modify your 4x4 block on the opposite side of the notch to accept what ever jack pad you have. Some have a four-tooth jack pad that can be imprinted on the bottom of the wooden block and "routered out" to allow the four jack jaws to fit in so there will be no slippage.
|Finally, and answer to your Franklin Fuel Pump problems...
Memeber J.R. Ranney has the solution to your Franklin Fuel Pumps. His excellent write-up is here as well as information on Bruce Hind's December 2011 newsletter. You can contact JR at email@example.com.
I'm sure all your Franklin guys are happy to see this! Thanks JR!
UPDATE! A few addiional notes on the Franklin fuel pump thing:
It was Walter Windus who discovered (or rediscovered) the source of the repair kits, not me.
I've just been on the phone with Rich Brumm. He said he's used these repair kits before and had bad luck with them. In one case the end of the diaphragm plunger broke off, and most of them start to leak after 100 hours or so. The kits he used did not have the "-A" on the part number, so they might or might not be improved.
J. R. Ranney
(Ed note: As with anything after-market, use these kits at your own risk and please let me know how they work out so I can pass on the good or bad news.)
See a photo of the kit here.
Use this PVC pipe to hold your control column back to make it easier to work on the elevator trim tabs or instrument panel items. It never ceases to amaze me the uses we find for PVC pipe. This small section of 1-1/2" pipe is smoothed out on both ends with one end having a curved cutout to fit the control column. I use this at least every annual inspection and usually a few times in between! A hole is drilled in one end to allow hanging on the wall (like a broom handle). Cost? about 10 cents!
|Keep an eye
on the aft compartment! This tool makes it easy to dry out the aft
compartment after a day on the water....
Have you ever tried to get that water out of the last hull compartment? You know, just above the tailwheel. Two little areas on either side of the tailwheel never drain completely and if left outside or in a less than adequate hangar the water just sits there, waiting patiently for corrosion to begin. A tool I found helpful is nothing more than a four or five foot piece of PVC pipe cut off at an angle (about 30 degrees to the longitudinal axis of the pipe) and used as a paper-towel-pusher-downer! I wad a paper towel into a loose ball and poke the PVC pipe down into the recesses. I then use a pair of mechanical fingers to retrieve the paper towel. Caution: DO NOT leave the paper towel in the compartment!
Open the aft access panels on each side forward of the horizintal stabilizer. Wad up two paper towels and throw one in each corner of the aft compartment.
Poke with this tool to get all the water absorbed then use a pair of "mechanical fingers" to retrieve the wet towels. This keeps your aft compartment dry as a bone. I use corrosion-X or LPS 3 liberally after the aft compartment is dry.
strut scissor links installed correctly?...
Below is an excerpt from Captain Dick Saunders' newsletter from around 1988. The lower scissor link on each strut should be to the OUTSIDE. See the illustration below: The illustration shows the WRONG way to install the scissor. I don't claim to know why Republic felt this was necessary except it allows for toe-out adjustment to tame unruly ground handling. Your guess is as good as mine!
Click on image for full size view
If your scissors are wrong, before you try to change them, jack up your Seabee so the gear is off the ground. Depressurize the strut and take the schrader valve out of the top of the strut and then and ONLY then change the scissors. Trying to change the scissors with the gear on the ground and fully serviced can cause damage to the airplane and injury to you or worse! BE CAREFUL!
See the Owner's Manual page 40-41 for complete instructions re-servicing instructions.
Gear Struts Leaking?...
Here are instructions for changing your Sturt O-rings. Please get the assistance of a qualified FAA Mechanic when you change these as it is a requirement to make a logbook entry. Need o-rings? Get them here. (NOT FAA Approved, NOT PMA'd.)
Tip (from member Rob den Hartog)
If you are interested in new door handles, this may do the trick. They may not be EXACTLY like the originals but they are close and very resonable in price.
The company is Austin Hardware. They have almost everything! check them at www.austinhardware.com. A data sheet for the handles is located here.
The only modification required is to cut the square shaft to length, drill and tap the shaft for the inside handle. I believe Austin also has inside handles as well.
submersible fuel hose and large connector hose...
Tip... (from member Neil Kennedy in Canada)
"I'm not sure what everybody else would find in their fuel tank, but when I was doing a small repair to the tank lid, I found that MIL6000D rubber hose had been used from the pick-up screens to the AN bulkhead fitting in the steel lid. Checking the specification for that hose, it can swell up to 85% when submerged in fuel..This swelling was obvious at both ends of the hose when I took off the Aeroquip hose fitting (top end) and the hose clamp (bottom end). I've replaced those hoses with 3/8 ID submersible fuel line hose by Gates sourced from the local auto parts shop. Gates sells a 10 foot length in a box (Product # 27081) for not much more than $20. With a bit of determination, and lubrication, an Aeroquip 471 hose fitting will go on the end of the hose. I found that the OD varied slightly along the length of the hose, so I picked a thinner section for the hose end to get the Aeroquip fitting on."
Fuel filling hose, you know, the large one!: While the tank lid was off, I also decided that the 2.5" ID rubber hose coupling between the fill tube and the tank lid needed replacing. There are similar couplings available in silicone, used in automotive induction systems, but they aren't recommended for use with fuel. Goodyear makes fuel fill hoses in many sizes (including 2.5" ID); however, but I had to buy a 4 foot length. This stuff wasn't cheap - trade price was $100 plus tax. It's good heavy duty fuel hose, though. Not permeable at all. For those who want to replace their old coupling hose with a piece of new Goodyear hose, I'll cut and send a 5" length (lots more than you need) for $25, including postage. E-mail to firstname.lastname@example.org if interested.
Check the "Parts for Sale" also.
Control bushing removal and installation tool...
If you find the need to remove or install the hinge bushings in your Seabee, you can make this tool in about ten minutes (not counting epoxy drying time) that will make the removal and installation a breeze! I have used it a dozen times or more and it works flawlessly. Download the instructions here.
Also a ball-bearing replacement for all the Seabee bushings are available from www.BearingsDirect.com (part number: FR168-ZZ for the flanged bearing and R168-ZZ for the straight bearing). Specification sheet here. This is a really neat fix for a heavily worn part of our Seabees.
CAUTION: Be sure your hinge-line on the rudder and flaps (three hinges) are in alignment! These bearings are very strong but alignemnt is critical. The ailerons are not a problem because there is only two hinges. Use this tip at your own risk.
for elevator trim hinge pins slipping out...
I was flying back from Hammondsport, NY and noticed a high frequency vibration in the control wheel and in the seat of my pants. Looking out at the wings and in the wing float mirrors I didn't notice anything unusual. I thought a flap or aileron was flapping in the wind. It wasn't. Changing airspeed had little effect on the magnitude of the vibration. I had no choice but to wait until I landed to check it out. After landing I did a thorough walk-around and didn't notice anything until I raised the elevator to the full up position. What I saw made me light headed! The right elevator trim hinge pin had come out almost half way! I would not have seen it if I didn't lift the elevator and looked underneath. The left hand side was fine but when I got home I drilled small holes in each end of the hinge and put a cotter pin in on each end of the hinge to keep the hinge pin in place. I did both sides of each hinge. I noticed that on other Seabees the hinges had been "crimped" to keep the pin form sliding out and upon closer inspection mine had been crimped too! The pin just wore itself out and was sliding sideways. CHECK YOUR HINGE PINS! This could be quite serious if allowed to progress!! If you want more information contact me.

Plug solutions for the numerous holes in our Seabees...
(Ed note: The following was received by member Bob Gould, Hawaii. I got a few free samples and they look great! I think they could work in quite a few areas on our Seabees)
I went online looking for something to use to cap the fuel vent line to keep water out when I wash down the airplane, and found FPT9430 Pull Tab Vinyl Plastic Caps at MoCap http://www.mocap.com/plastic-caps-pull-tab.html. I asked for samples of them in that size and the next size up, along with several other types that seemed like possibilities, but the FPT9430 work best. They fit fairly tightly on the vent tubes, are long enough to work with (2.25") and to punch a hole through to attach a "Remove Before Flight" ribbon, have a kind of handle, and seem like the right answer. I asked for red and got black, but that's OK.
They also have SHEET METAL FLUSH PLUGS for the access holes in the wings, etc., though I have gotten mine from Caplugs previously.
Both MoCap and Caplug sent me samples; MoCap 3 of each of several types, and Caplug 10 3/8" ones for my wing leading edge holes at no cost. Normally they want people to buy thousands at a time, but I don't know if there are retailers or how small an order can be made and at what prices.
I thought you guys might find them to be useful additions to your product line.
Member Tim Sutter offers his take on corrosion. Fresh water seems to be no problem or at least not as much as salt water.
I thought I would add my two cents to the corrosion inspection (lift struts especially) issue. After several years of doing the annual inspection on Bob Gould's SeaBee in Hawaii's horrific salt water environment I would recommend to never use a sharp object to compromise the paint seal on any aluminum component. Even the smallest pin prick will allow salt water to enter. Any corrosion is very easy to observe by looking for the swelling in the paint. Even the most insignificant corrosion will show up as a bubble in the paint. I use a strong light and position it so that any sign of corrosion is seen in the reflection of the light off of the surface.
On my airplane, in a fresh water location in Alaska I have yet to see any corrosion at all. Tom Eldridge's Seabee has minor corrosion on the rear spar of the wings. That corrosion is due to salt water time in Washington before Tom purchased it. The rib in one horizontal stabilizer had to be replaced also due to corrosion.
I have four hulls sitting outside, with mud inside the bottom of the hull compartments. The mud can be scrapped away and the original primer is still intact. I did look at one Seabee (N87549) in Wassilla Alaska few years ago and it had some corrosion issues. The keel had exfoliation in several locations. I don't know about its history other than it had sat in a very damp outside location for about 30 years.Thanks Tim"
Bubble shows where corrosion hides underneath. Tim says don't poke paint with a pointy tool instead just keep looking for the bubbles. Other photo is of a hull Tim mentions above that has been sitting for years in a fresh water (rain and weather) for years. Not in bad shape considering.
easy hull stand for the Seabee...
From member Robert de Hartog a simple and cheap (about $75) alternative to the complex hull stand listed in the Seabee Service News No. 4. Below is the ad from Robert (left) and a photo I found on Ebay (right) . The only thing I would add is a secure support on the top of the ladder to prevent slippage and make sure it can hold all the weight you would possibly have on it. Thanks Robert!
Rudder Gust Lock idea...
From member J.R. Ranney N6748K; another idea for a rudder gust lock. Made of steel tubing with "J-bolts" as the locking devise. Thanks J. R.
(Click on images for full size view)
From member J.R. Ranney N6748K
Attached is some information on C.R.Laurence (website: http://www.crlaurence.com/) AS1615 rubber molding that works well for Seabee windows. It's one-piece with an integral locking strip.
Belt for the Franklin....
From member J.R. Ranney:
The Franklin generator drive belt part number is: Napa 25-22386, or Gates TR 22386. A slghtly shorter belt would probably be better. With this belt installed the generator adjustment is at maximum.
From member J.R. Ranney:
Someone suggests oiling the hull drain plugs before installing them. A better way is to use Teflon pipe joint tape; it's less messy, it provides a perfect seal and makes them easy to remove. Pipe joint tape can be used on oil, fuel, and hydraulic fittings as well, but be careful to leave the first thread or two free so no tape gets into the systems.
and Baggage Compartment Cover...
Here is a real timely source. I purchased an interior kit for my Seabee from Airtex (http://www.airtexinteriors.com/) back in 1979. It came with an anchor bag and also the canvas baggage compartment curtain. I assume they can make you one. The snaps came with the kit, but were not installed, as you have to fit them.
Pedal Gust Lock (You can make it yourself!)...
(Ed Note: This tip is from "Master Seaplane Newsletter Writer" Bruce Hinds of the Northwest Seabee Club. He has a great solution for the rudder pedal gust lock! Thanks Bruce!)
"My aircraft at one time had the rudder stops broken out because the airplane was parked in a strong tail wind. The mechanics had cut a hole into the rudder skin to do the repair and the finish has never been the same. Another bee this past year on our field was in the shop for an extensive repair for the same thing, except it was the former and plate on the vertical stabilizer the hinge mounts to that was damaged. That was a very costly repair. Locking tail wheel airplanes don't have anything resisting rudder movement like the springs on the steerable tailwheels. Perhaps you remember my rudder lock (see below). It's been a few years, but I used someone else's idea of putting two "pins" on a wire and flag so they go in the middle rudder hinge. I coated the carriage bolts in a rubber stuff made for tool handles and drilled the carriage bolts for a sprinkler marking wire. It's worked great all these years. But....."
First Rudder Lock
"When I showed this to everyone, I received a story about how a problem that could arise should you forget to remove it! "Not a problem" you say? Well on land you can't taxi without noticing it, that's correct. But as the story goes, and I can see this happening, when parked on a beach, 9 times out of 10, especially on soft beaches you get the airplane in position to go down hill when you park it. So you forget, and power up straight into the water! Try to get that sucker out now! How are your sailing skills without a rudder? I've been looking for alternatives because even as well as this has worked, how do you get it in and out at a dock? And another flaw with my arrangement is when the wind is blowing from behind and the airplane is parked, you can still get some rudder banging unless you have someone hold the pedals while you pull the pins.... Yes it's not perfect and the other situations haven't been much of a problem, but my mind has been looking for a solution. Recently in reading the old newsletters I noticed a "U" shaped bracket they mounted to the battery box with a piece on each end that would attach to small bolts threaded into the inboard ends of the rudder pedals on the copilot's side. Great idea, but I didn't want to put the bracket under my carpet job and I didn't want to pull the pedals out to drill and tap in the bolts. Can't we make this easier? Yes!...
New Generation Rudder Lock
"In it's former life this rudder lock (above) was a wardrobe box hanger bar (available from a U-Haul store). Now shortened and painted bright orange with web straps that wrap around the back of the pedals, pop riveted on the ends and snaps in the middle. Can't miss it! Even if you do and you find yourself 'underway' on the bounding mane, you can pop the snaps and you're home free. The only drawback on this is there will be just a little rudder movement, but it can't move much!"
absorber for tail wheels...
Members Mike Lush and Brian Robertson from "The Great White North", have invented a new shock for the tail wheel on our Seabees. Works on steerable and locking tail wheels. Evidently the humongous spring was the big hurdle ($$). For a detailed file (PDF) click here!
Price is $1975.00 USD.
Mike and Don write:
"Yes! Finally a shock strut is available for your Seabee. Improved ground handling, and a much better ride for you and your old Seabee, especially on rough runways, is now available. High quality components, plus ease of installation, make this the perfect mod to replace those old rubber pucks.

|More on the
Seabee Hydraulic Pump...
From Bernie Nolen (firstname.lastname@example.org), Thanks Bernie!
The electrol hydro pump from simuflight (I think he means Prestolite Pump - Steve for the IRSOC) came from the tilt outdrive actuator off a boat. Most of the ski boat runabouts use this to control the tilt and trim of the out drive in an Inboard/Outboard installation. Try the local boat repair shop.
I'm sorry for getting back to you so late. My prestolite pump works real well. The flaps take about 5 seconds to go down and about 7 seconds to retract. The gear takes a while longer (about 20 seconds to retract and 15 to go down). I haven't seen a Seabee gear retract much faster than that. Not that it is so fast it's just the nature of the beast I suppose. The "valve body" has alot to do with the efficiency of the hydraulics as well but they all seem to work flawlessly if they are maintained well.
I have no complaints about the Seabee hydraulic system other than the parts are a little hard to find. If you need someone to work on it, I would recommend Richie Brumm in NY (Seabee Owner and member). He is the hydraulic expert hands down.
Please keep me updated and I will include your information on the website for others if you don't mind. Thanks!
for the IRSOC"
I will keep you posted on Oildyne/Parker pump progress. The electrol is an easy one to work on. As for the Prestolite according to Air-Parts of Lock Haven, it was also used on Aero Commander 112/114, Beech 24/26, Bellanca 17-30 series, Cessna 177 RG, Piper 28,32,34,44. These could be a source for prestolite parts. Thanks.

(This Tip comes from our friend Bruce Hinds out on the west coast. Thanks Bruce!)
Even the professionals make mistakes, an interesting story in the Kenmore book was about an annual on a Bee. They delivered it to the owner who wanted it right away for an event at Whidbey where he moored it for several hours. The plugs were left out and not noticed. The owner returned from the event to find his Bee floating upside down. The story of the recovery is even more amazing. But that's another story.I drill a small pilot hole in the bottom, or in this case the top of the plug and braise or hard solider in a piece of braising rod. Bend a hook in the end so it will fit though the hole, then when you push it up in the hole all you have to do is hook it inside and pull the bend a little bit wider. This has worked great, they're easy to see hanging down and you always know where they are."

Pump Plug Covers...
To prevent a TOTAL hydraulic failure and the embarrasment of landing with the gear up on a runway or worse with the wheels down on the water, make sure your Electrol Hydraulic Pump (the manually operated one) has the plug covers installed. Some covers have rivets driven in from the pump side so that the head just touch the plugs when the covers are tightened so that the plugs will remain in place regardless of plug integrity. See a rough sketch here and check it out on your airplane TOMORROW!! The aluminum plates are about 1/8" thick and the screws are #8 or #10 machine Phillister heads that are safetied together in pairs. The plate on the aft side of the pump body may be made as one piece but still has four (4) screws in it for security.
Caution: If your pump body is not already drilled out for the plate screws (#8 Phillister Head) be very careful about the drill depth as there are numerous cavities and passageways that are not too far from the surface of the pump body! Mine are about 1/4" deep, that's all! Use a bottoming tap to prevent the tap from piercing the Pump Body orifices.

| Corrosion Proofing...
Here is a tip I got from Henry Ruzakowski. He has been operating his Seabee in salt water for years, and recommends using LPS-3 to prevent corrosion, it is, in his opinion, just as effective as Corrosion X or ACF-50 but is less expensive. He also uses an LPS product called Hard coat for fittings and bolts. He uses the Corrosion X spraying system to get the LPS into the interior of the structure. The spray system costs about $400, but that may be a good investment.
All the best,

| Trim Tab Lock...
The following clip is from the December 1984 Newsletter from Capt. Richard W. Saunders' and his device should be in every Seabee owners' inflight toolbag.
"Another “voice of experience”, Karl Johnstone, relates that he learned the hard way about the trim tab on preflighting the airplane. One of the most serious occurrences that the Seabee can spring on you, and has done so to three owners that I know of, is trim tab failure in flight. All three were extremely lucky to have survived. The Elevator Trim Tab Actuating Rod and the Fork are the culprits. Of the utmost importance on your walk-around inspection, and whenever you fly in some one else’s ‘Bee – check the play in each trim tab. No more than 1/4" play should be in the system. Think about this: if the trim tab becomes free in flight, it’s going to move with the airflow change. Any movement of either tab is going to cause the elevators to move to full travel up and down, under the influence of that big, free-floating trim tab.
Imagine the ship’s pitch changes when those big elevators are oscillating stop-to-stop. Now imagine trying to get her safety back to earth in that condition. It happened to the Judge and to a long-time friend in Texas, who described it as a miracle that the oscillation of the nose just starting an upward curve coincided with his being only about 5 feet above the surface of a lake. Gave new meaning to the term, “We just dropped in”. The oscillation could have been in the middle of the downward curve when he was that close to the surface. A footnote to that incident: his passenger on that flight was his priest, up for his first plane ride. Divine guidance?
In my tool kit/spare parts, I keep a bolt, nut and two skin washers together so that if I find a loose tab while 58K and I are away from home base, I can secure the bolt/washer arrangement in the slot between trim tab and elevator, thereby locking the tab to the elevator. It’s like a miniature gust lock. Go put it together now.
Judge Johnstone’s incident was probably the same lucky coincidence of the oscillation, but resulted in a $20,000 repair bill, even though he was able to fly his tough old bird, the Seabee (Twin), back home after tightly securing the trim tab. He had “landed” in snow-covered tundra."

| Parking Brake...
(Long-time IRSOC member Bruce Hinds, editor-in-chief of the Seabee Newsletter,sent this along. Bruce, I can tell you that you are not alone!!
The good news is your parking brake valves must be in pretty good shape! Steve-for the IRSOC)
"Someone passed me a picture recently of an Airbus with all the tires blown due to some bonehead landing with the parking break set. I have heard of this before, mostly in small planes and I've wondered how that can happen. Here's one way:
At Lake Goodwin I was to work the event on Saturday and didn't want to take a buoy just in case we had a bunch of folks show up. Besides, if I put it in shallow water I could walk to the dock. This wasn't something we encouraged due to some big rocks, but I'd been there several times getting things ready and knew where most of them were. So, as I taxied in to the shallows I just figured I'd put the gear down and that would stabilize the airplane on the bottom and I wouldn't have to anchor. I've done this before, it works great.
The airplane was mostly afloat, and there were some waves, so just to make sure it didn't go anywhere I set the parking brake. Can you see this coming? The airplane sat fine all day long. When I was ready to leave, I just powered out. It seemed like I'd snagged a good size rock on the gear or a wheel was in a hole which stopped my progress, so I selected the gear up and away I went. There was a pretty good wind blowing back at the Narrows when I got back and with a short ground roll I made my taxiway, turned off the runway and came to a stop. Hmmm, I didn't plan on stopping. But with a right turn into the strong wind, I just need more power to taxi... more power... more power? What's going on here? That's when I realized the brakes were still set. What a Bone Head!
Seems odd, just that weekend I'd talked to someone that had put the Cessna 421 8" brakes on his Seabee. He questioned why the STC was for 6" brakes on an 8" wheel, and, I'd wondered what it would take to upgrade to the bigger brakes. Fortunately the 6" Clevelands on the Bee are sufficient to hold it in place with full power. That's all I really need!
It would seem silly to have the parking brake on the landing checklist, but who knows? Just be careful if you use your brakes while parking in shallow water.
CHECK YOUR CHECKLIST!

|Hull Leak Adapter...
If you are draining more water out of your hull than you think you should, you can use this simple device to narrow down the leaks. It's simply an aluminum tube with a 1/8 x 27 NPT thread to match the existing hull plug holes, a garden hose shut off valve and a female hose end. Total cost? About $3.00 US. You can attach the garden hose to the adapter and fill each compartment and watch for the drips. It may take a little searching to find the leak but at least it's a start.
