Model T Ford Forum: Forum 2012: Crank Shaft seal repair

I need to replace the crank shaft seal on my 26. It's throwing so much oil out the front of the engine it's affecting the track of the fan belt. I will be using a "speedy sleeve" to go over the area of the shaft where the seal contacts it because the shaft has some shallow grooves in it in that area. What is the preferred type of seal, rope or modern neoprene? I'm puling the engine out to do this so I'd like to do it only once. Thanks.

Chester, the Model A rope-type front seal is
preferable to the original Model T felt seal.

Back in 2010, I used a modern crank seal (Snyder's Part T-3012-M) on mine embedded in "The Right Stuff". It worked great, as there is virtually no leakage from the front shaft, however, when I did it, it was during an engine overhaul. If you are not doing an engine overhaul I don't know how you would go about properly installing a modern seal. Jim Patrick

PS. While I was at it, I also installed a modern cam seal (Snyder's part T-3177-M) on the camshaft with the same good results.

My crank had groves in it when I put it together.." I should have Speedy sleeved it" but with the model A seal it didn't leak a drop.

Chester. Jim is right and I've posted this trick several times here.

If your crankshaft seal is leaking you should install one of these seals. It's a piece of cake. Use the Right Stuff by Permatex after you clean off the surface area. I just cut and flattened the seal flange like a daisy and fit it to the front.

Garrett Green told me about this great idea and I've used it a few times and always No Leaks
