Model T Ford Forum: Forum 2017: Front crankshaft rope seal
Top of pagePrevious messageNext messageBottom of page Link to this message  By Glen McConachie on Friday, September 29, 2017 - 08:38 pm:

Hi Guys

We are just working on final assembly of a couple of Canadian engines ( 1922 1926) and have found the 3012R rope seal we have bought from Langs sits quite a way out of the seal groove.
should I look at getting the 3012RE seal instead or does this pack down when assembled against the crankshaft?
We just do not want to damage the front plate or anything else trying to assemble with a seal that is just too big.

I look forward to your replies

I have never been able to make that rope seal that Lang's sells fit in any engine. Don't know why they can't sell the right thing.

I use the Model A type "rope" seal. After I get it seated using a socket about the same diameter as the crank and hammer it down into the groove on both pieces, there is more then what is needed sticking up on the ends. I trim them back about 1/8" above both the cover plate and crankcase. Remember the pan gasket fit in between them too.

I use them all the time. They work very well, follow Mark's advise and you should not have a problem. Once the seal is seated I give it a light coating of grease.

Again, how can we help you when you fail to mention the year of your car. Yes, a Model A rope seal works fine on the late T's, but not the early ones.

I used the same socket method on Derrick Pang's engine. Saw the way Mike Bender shows on his video series .

The fat A model rope seal is usable on late non generator motors as well as the generator types. As Larry pointed out, earlier cars had a smaller seal groove in the casting.

Now is a good time to suggest that you also install a modern oil seal on the outside of the front cover if you want to stop that oil from wicking through that rope seal. Some people use the neopreme seal inside like Bob posted but I prefer it on the outside so the cover comes off easier later.

There's a lot of posted info how to install that seal.

Larry,

Was that necessary?
