Topic: Cluster Gear Shaft with O-ring Seal


MOXIE    -- 04-13-2010 @ 7:20 PM
  My 35 transmission leaks from the back where the cluster gear and reverse gear shaft come through the casing. Someone makes these two shafts with o-rings on the end to seal for leaks. Cannot remember who it is. Does anyone know a vendor that has these, thanks?

  Have a machine shop groove the case for O rings. That is far better then grooving the shafts. This has been done on lots of cases by a couple of local V8 ers and nobody has had any trouble. My 39 trans in my 32 roadster remains leak free after many years. If you were in the Seattle area I would put you in touch with the person who does it for us.

  If you do not want to pull the transmission,
I would drain the trans, remove the bolt that holds the locking plate in place, and spray with a very good cleaner, and use a sealer like JB WELD,around the shaft ends, with a paint brush,then let dry,
hey its worth a shot, removing the trans is not a easy job,
hope this helps, 37RAGTOPMAN
it will solve the problem or slow it down,
if you have a major oil leak you have more problems,
like a worn case

  I have used Locktite thread sealer to solve the leak on these shafts. This is an invisible repair, like the O-ring.

I would recommend removing the transmission from the car, so that the shaft can be moved toward the front of the transmission, the sealant spread in the hole and then the shaft pushed back into place.

I would not use JB Weld, as this would make rebuilding the transmission more difficult. Permatex or silicone sealer would be better. This is not an invisible repair.

  We have made o-ring grooves, but it requires complete disassembly of the transmission to extract the shaft. Leakage from Ford transmissions seems to be usual from the very early days. When I had Model A's, we used a bolt-on cap to contain the leakage from the shaft port in the case. It was secured by the bolt that holds the end of the shaft. Try a heavier oil, such as 140. It won't stop the leak, but it will slow it down considerably. Also, don't fill the transmission beyond where you can find the oil by crooking a finger down thru the filler.

On the JB WELD, I said use a paint brush, using very little, just where the shafts come out of the back of trans,next to the shafts, you could also use #1 or # 2 permatex,, or a silacone sealer , but not glopping in on,
this will not hamper and removal of the shafts later on,and once painted will not be noticeable.
and use a heavier lube, buy from the MODEL T and A FORD PARTS VENDORS, # 140 250 600
Hope this clears this up,
My 3 cents worth 37RAGTOPMAN
