901 transmission main bearing seal
I've heard its possible to change the main bearing seal in a 915 while the transmission is still in the car, posted on this forum. Has anyone done this on a 901? Same procedure?

My understanding is the early 915s required disassembling the transmission to change the main shaft seal. I know this was the case with my 73.5. The switchover was sometime in early calendar year 73. Wevo can modified the case so that the main seal can be replaced without disassembly, which I had them do on my case.

I think he's referring to the shift rod seal at the end/nose cover of the transmission. Because there's no way the main seal (behind the release bearing guide tube) can be replaced with the transmission in the car. Not unless you remove the engine and then you might as well remove the transmission if you've already pulled out the engine.

+1 I think he is talking about the "nose" input seal. Yes, possible but very cramped space

That's it, the seal in the nose. I had a look under there last night and it is incredibly cramped! Worth it for the odd drip? It might keep for a rainy day, and not too many of those this time of year in Queensland, Australia!!

That seal can be finger pressed in. just raise the front end high as you can safely ( this will limit spillage ) , disconnect coupler, remove input shaft to chassis tunnel boot and crossmember if needed, support the gear box with a jack or stand. Use a small screw driver rapped with tape and work the old seal out.
Use silicon or assembly lube and slip it over the shaft and down to the nose, finger fit flush. put everything back. Nothing will go out of adjustment. That's it. Leak will just get worse and you will have boot full of gear box oil one day if not addressed sooner. While you are there, check level of gear box fluid but on level ground of course. Heck if she has not been changed, take the opportunity to change it, she will be happier  My 2 cents.

I had a similar leak that my wrench said was due to the input shaft being worn. When I changed gear box fluid a few months later, I added a bottle Lucas Transmission Fix. Besides quieting down a whine, the leak has all but disappeared.
