Seals on a 3 speed trans.

Recommended Posts

Anyone ever replaced the axle, input and brake shaft seals without splitting the transmission? It looks like it could be done with a bit of care. I can't find any excess play in any of the shafts. Looks like they just wore out. Took about a bushel of grass clippings out from under the seat and BGB. The victim in question is a B112. Ron

I just replaced my axle seals. if you do it carefully the seals can be "dug" out of their pockets. Seal bodys are made of relatively soft thin metal and can be punctured and pryed out without too much difficulty. Screwdrivers have been my weapon of choice for this operation. Possibly a tool made for this exists, I dont know. Dick

I punch a small hole in the seal and screw in a sheet metal screw. I then use a small, forked prybar, such as a "cat's paw", for pulling the seal. Has worked very well---most of the time. Pat

With the axle and shafts in place you will need a special tool to go over them in order to seat the seals. In the repair manual it shows seating the seals with the axle in and the special tool. You should consider replacing the case gasket too. I just rebuilt my trans. I'm glad I split the trans. because that old gear oil was gunked everywhere. Nice to clean it out. Wasn't hard to split. Hope this helps. Jim

I would agree with Jim. Splitting the transmission is really not that much extra work. In addition to the seals being easier to replace this way, it also allows you to have a look at the bearings, potential gear wear, etc. at the same time Pat

Carter, if you decide not to split the case and just replace the seals, wrap clear shiping tape around the tubes to protect the seal from damage caused by the keyway. It is quick and easy if you don't have a set of plastic tubes to protect the seal.

Thanks All, Good input. I'm still removing the 2" of accumulated dirt and the side plates from the trans. Going to have to take a month off and go to Florida so nothing much will happen till March. Appreciate your thoughts. Ron

A wrap of tin fiol works to protect the seals from keyways also. I'd say split the tranny just to clean it out good, lay it cover up on a milk crate and everything stays in place..MPH
