I got a '54 Super 88 Diesel and I have the clutch housing cover off and the back of the engine is pretty greasy and oily and it had some oil accumulation in the housing. I'm guessing the rear main seal is leaking. So I need to pull off the clutch and flywheel, take off the cover and put a new one on. I can replace the seal without removing the crankshaft from the engine, right? Is the seal put on with a press? Any other tricks or hints to doing these? Any insight on this would be helpful. Thanks in advance

I had a similar problem with my 1952 77. I bought a standard lip seal and attached it to the inside of the metal face that the old cork seal ran on, with engine epoxy. I used a few small spots of epoxy at first to make sure I had it centered properly and then filled the cavity with two tubes of epoxy. I learned how to do this from a guy that builds and runs dragsters. He assured me it would work. If you want to remove it just heat it with a torch and the epoxy will melt off. Don't worry it won't melt at engine tempeature. For the front seal I had the old metal face milled off the front cover to accept a standard lip seal the same size as the old felt dust seal. It sits where the dust seal was. We have run like this for about a year now with no problems.

Yes the seal can be replaced with the crank in.You can carfully tap the seal in with a hammer and punch.You will have to remove the long pto shaft from the rear.If the crank is worn try to install the seal alittle farther in or out so it rides in a differant spot.The lip of the seal points in.

Larry, I hope I'm not talking out of turn , but all the ones that i have seen have the cork face seal. I just made a seal retainer to use a standard
off the shelf lip seal . I can email a picture of it , but it will take a few minutes to put it up
so I can post it.
