Finally getting back to getting my engine back together. I noticed some decent groves on the damper/pulley, and wondering if I should use a Speedi-Sleeve. My trusty Tom Monroe engine book doesn't mention anything about them. And if they are used, the seal is riding on a bigger OD which may fail the seal sooner. Or should I try to place it in the cover at a depth where it avoids the grooves, like I did with the rear seal. Attached is a pic, what do you think?

 

Also, the factory color for the water pump pulley is black, right?

 

Thanks, Ken

When I bought my 77' the PO said it used about a qt of oil every 700 miles.  Turned out the that quart of oil was going out of the front seal as evidenced by a Exxon Valdeze type goo all over the front half of engine.

I used a redi-sleeve with a new front seal and it worked perfectly.  I've got around 3-4K on it and no leaks yet.  Was yours leaking oil from there before the build?

Sorry, don't know if the factory pulleys were painted or not..

I'd go with a speedi- or redi-sleeve.  I eyeballed my rear seal on my current engine and decided that since it was dry and didn't show signs of leaking that I would avoid the minor hassle of replacing it before installing the engine.  But it had been sitting 0 years, in a parts car, and the seal has started leaking, and it's getting worse.  Wish I would have put the extra effort in to making it better when I had the chance.  Your part is much harder to replace if your pseudo-fix of positioning the seal doesn't work.

I don't remember it leaking before, just trying to avoid future problems. I guess I'll go the sleeve route. Anyone have a part number for what works? Damper shaft is 1.889" x .60" long (260z block). Or a Z vendor that sells them? Thanks.

I got it, SKF 99189.

I got one from O'riellys's next day if you need one in a rush.

Rock Auto and Amazon have the sleeve.

The water pump pulley should be bare cad plating.

I used a speedi-sleve on my FJ40 Emergency Brake drum and it works well. I do not believe that you will have an issue. I used the Loctite sleeve product (green I believe).

Okay, got the sleeve on, thought I'd post a few pics.  Put thin coat of silicone on inside of sleeve, and pressed it on.  I suppose a mallet would have worked too if careful.  Ready to go.
