Input Shaft Seal

[firemedic355]

After hours putting in my new Tranny/TC it was leaking a stream of fluid after warming up After some advice here and pulling it, I confirmed it was a damaged input shaft seal (around the main shaft)

I've never done a shaft seal of any type before. I got the new seal and a seal puller from Autozone. Any recommendations or advice to make the process go easier? I'd hate to spend 3 hours putting it back in only to have it leaking again.

Pull the seal with the tool. Look at the tc hub and make sure there are no scratch marks around wher the bushing rides. Use a very little amount of silicone glue around the metal part of the seal that mates with the pump. Wipe all the fluid off the pump. You really need a pipe that is the same diameter of the seal to drive it back. Most people try to just hammer it in and just damage the seal.
What color is the rubber part of the seal. Needs to be black or blue, not grey.

Yeah, the one I got is black, it's the Timken one from Autozone.

You mentioned I should get a seal with black rubber, not grey; why is this? The Timken one I got from Autozona actually turns out to have grey rubber. I went around town and both Checker's and Pepboys had the same chinese made cheap looking seal, but it has black rubber. Which do you suggest? From appearance the grey Timken one looks much better quality. I'm not even sure the cheap chinese black one has the compression spring around it to help it seal on the shaft.

The compound in the grey seal won't hold up very well to heat, ect...I use the non-Viton (not grey) seal although the Viton is way better than the grey.

Do you know if the SKF seal I got from Checkers, part #19799, with a black seal happens to be a non-Viton seal?

I couldn't say, I don't know where Checker gets their stuff. It's got to better than the grey.

I think the black is Viton and the blue is silicone.

I always replace the front pump when this seal leaks. There is usually enough wear on the bushing in the pump that if you don't replace it it could leak again.

Why not just replace the bushing in the pump. That is what wears. Costs about $4 instead of $140.
