Hi, i'm ready to put the timing chain cover on my TR4 motor but I can't figure out how to remove the old oil seal, or how I would get the new one in there. I've got the shop manual but it just says to renew a worn or damaged oil seal, a bit vague.
 
The seal basically just pries out, from the inside of the cover. Tap the new one into place with a hammer & block of wood or similar.

Don't forget to apply grease to the lips of the new seal & the crankshaft surface, before installing the cover.
 
oh, ok, so just pry it out with a screwdriver or something of the like?

What kind of grease do you recommend?
 
There's a tool called a seal puller that works something like a claw hammer to lever the seal out.

Available at Pep Boys or equivalent.

Or a screwdriver.
 
ok, thanks, I got the old oil seal out, but the new one doesn't look much like the old one. The old one (the one on the left) is a little deeper and has a lip on the outside, the new one (on the right) is not as deep and has no lip. Is the new one ok to use?

The type of grease really doesn't matter, the seal is normally lubricated by oil splash from the timing chain. Just needs something slippery to last until it starts getting oil. I generally use wheel bearing grease, just because it's what is handy for me; but white lithium or grease gun would do just as well.

Yup, looks fine as long as the outside diameter matches, and the inside is snug on the crank journal. The materials have improved over the years, so the seal itself can be simpler (and cheaper to make).
 
Ok, that makes sense. They do appear to be the same diameter so I should be good.
 
Please dont neglect to inspect the outer hub for a groove caused by the seal wearing over time.This is repaired by a"speedy sleeve" that is OTC at auto parts but you will have to order it.

Thanks for the tip MD. I didn't notice any type of groove on the hub and the new seal went right in.
