Aileron/Flap Rods

[Robert Berryhill]

Has anybody changed the bearings?

Mine are in need of changing, I have printed out the blueprint, and both the numbers on the print and IPB are obsolete, and I’ve been unable to cross ref them dimensionally.

Thanks

Hello Bob,

Could you be more specific? There are…

A) The  76-62302 long push-pull control rods for the ailerons that go all the way into the fuselage, with a Stinson 76-62303 fixed outboard rod end and a 76-62304 adjustable inboard rod end, each containing pressed and staked bearings,

B) The short 76-62305 aileron push-pull rods that go from the ailerons to the bellcranks, of which there are two varieties with either the Fafnir RE2-M6A (early) or RE3-M6A (later) bearings.

C) The AN200-K3 bearings inserted into each flap bellcrank (aren’t any flap rods).

D) Something I haven’t covered?

Thanks,

Jim

Hi Jim,

I’m talking about the short rods, mine have Fafner RE3M6A and Fafner RE3H5, I’ve not been able to find them on Google or a cross  ref number, a Bearing Business, that I’ve used before contacted Fafner and they stated the M6A was no longer produced and no record of the H5 one.

Printed out the 76-62304 blueprint for the rod end Assembly and the 76-62614 for the flap rod and will be looking to see if just replacing the bearing  with one dimensionally the same is possible.

Hi Guys,

The short rod has an unthreaded rod end which is riveted into one end.  I am exactly in the same spot with mine and I am working a solution ( awaiting parts for comparison).  I will need a few days  to get solid answers worked out.  Bob , If this works like I think it will, I will get  set in process for you.

Robert: The 62304 was a custom rod end. It uses an AN201-K4A bearing. That number, as well as it’s updated version, MS27641, are available.

 

For the RE3M6A, look at the MS21151 specification and check the measurements.

 

Wag Aero has the RE3H5’s in stock, but hold on to your nitro pills when you look at the price.

Thanks much  for the heads up Craig!

Yes , the 62304 crosses over to REP3M6A bearing.

A/C Spruce  has both listed ( REP3H5  and REP3M6A).    FBO cost was $63 & $77  But I have not checked to see if they were in stock.

Bob, this  may be the quickest option  for acquiring them.

Sorry Bob, I missed the 76-62614. I thought that I remembered the flaps had pushrods but then couldn’t find them in the catalog yesterday. I just looked again and they’re damned hard to see (eyes getting old, I guess), but I finally found them and pulled up the drawing.

Anyway, Univair sells an REP5H unthreaded male rod end for Stinson 108’s that may be the same as the RE3H5, but they’re a whopping $85.75 each! Same price at Aircraft Spruce who also lists an REP3M6A, also for $85.75 that could be the same as the RE3M6A in our catalog. The AN201-K4A bearing that is staked into the 76-62304 rod end is also sold by Aircraft Spruce as AN201-KP4A (MS27641 series).  I’m not a big fan of AS on account of their prices, so if they have them, somebody else probably has them too.

The Univair GMM-3M-680 for the Stinson 108 may also be the same as the RE3M6A , but I’m not sure. Their price is $26.50, which is at least bearable.

It couldn’t hurt to try Earl Allen who parts out Stinson 108’s in California (advertises in Barnstormers). Last time I spoke with him on the phone two years ago he had stripped 50 airframes so may have a large collection of usable 3H5 and M6A rod ends for considerably less money. Just a thought.

Worth checking the drawing notes, as a couple of them, and I don’t remember which ones, listed a 10 series Stinson part number as “same as”.

[Robert Berryhill]

To everybody that replied,

thank you, all reply’s were very helpful and after spending a LOT of time measuring and comparing to MS drawings as well as from RBC Bearing Co and several others all the matches pointed to MS21150/MS21152/REP3H5/REP3M6A.

So long story short, I went ahead and ordered them from Spruce, there goes my next six tanks of gas lol.

Sam, could you please contact me at bearbait69@earthlink.net, I would like to talk to you a bit.

Again, a very big thank you to everybody that helped.

Bob: When you need parts, take the time to shop around a bit. You can often find the parts a lot cheaper elsewhere, but lead times may be a bit longer.

 

Jim: A thought… as we find these substitutions, maybe we should, as a group, put together a known interchange on part numbers that are no longer available, but have current substitutions.

Hi Bob,  I sent an email with contact info on it.  Did you get it?
