Title: Oil from speedometer cable entry
Post by: Fr Mike on August 29, 2011, 02:05:42 PM
What can I do to stop the oil leak from my '36 P2 where the speedometer cable enters the transmission?

I am on the road at present and do not have access to my books.  But---should there be a gasket, either cardboard or cork, inside the cup that screws onto the transmission?

Thanks for your reply, John. That's a good question. When the engine and tranny were out recently, we could not determine what the designed connection set-up should have been, and have been trying to determine it. Special fixture? Etc?
Will keep the forum informed re progress.

I found, in a Plymouth Parts Book, that there is a "speedometer oil seal" (Mopar part no. 652 840) that will fit my P2. It is a ring with a flat top and bottom, but open on the under side  for containing some kind of sealing material.

Maybe I can find one and "re-stuff" it or otherwise improvise.

Well, searching has indicated that the part (Mopar part no. 652 840, fits 1936-47) is about as hard to find as dentures for chickens. It has been recommended that felt or an o-ring can be used to correct the problem. I guess that's what I'll do.
