The Stovebolt Site Forums The Shop Area General Truck Talk leaky pinion seal

Got a leaking pinion seal in an original 57 rear end. I changed the seal, and when it was apart I noticed much pitting in the yoke surfaces. I changed the seal but is still slinging oil.
Many years ago, I made oil field salt water pumps last a bit longer by JB Welding similiar surfaces and sanding it smooth to fill the pits. Reckon this might hold up to oil and to this application for a while? Thoughts?

Welcome to the bolt! The JBWeld sounds like a plan to me. I've heard of guys using it to repair engine block cracks, so it should do the trick for you.

I think it souns like a real good idea to. Id just make sure she was good and clean before applying any.

Ive read here that people have used a speedi-sleeve on parts like this to. Havent had any experience with them myself, maybe someone will chime in???

Oh yeah, welcome! And wheres the pics???

Is it possible the grease is comeing through the splines. It,s a good idea to put a little RTV on the yoke splines before putting it on. Are the bearings O.K.? Loose brgs. can cause a leak also. The seals usually don,t leak that soon from a rough yoke surface, although it certainly shortens the life. You might check the parts store & see if a speedy sleeve is available for that. That is the best way to go.

57CHEVY501,

I used a spedi-sleeve to fix mine that had huge grooves in it. It worked great!

A local parts house should be able to help you choose the right one. (if not I think that I saved the old box from the one I used - I can try to find it).

A tip on installing it: Boil your sleeve in water and stick your yoke in a bucket of ice water - this way when you install the sleeve it slides on pretty easily. Once they equalize in temp it is on to stay!

Good luck.

Thanks for the advice. Never heard of a spedi-sleeve. I will try that and let you know if it works.

Rustednuts, pics? Are you kidding? With my computer skills? hehe I'll work on that. This is the start of what looks like will be a long project. Work until the money is gone. Save more. Work. Save. You get the picture.

Thats the problem, we didnt get any pictures!

I have used speedi sleeves for years. It will definitely give the seal a good surface to ride on, and is a lot cheeper then a new yoke. I put one in my wrecker last year, and it hasn't leaked since.
Good luck, and welcome to the bolt.

I've also heard them referred to as "redisleeves"-of course we don't speak english around here. That's topic for a different day.
