Crank pulley in trouble??

[cruiserloser]

I pulled-off the crank pulley to find this. I assume it is not normal for the sealing surface to be scored like this......thoughts? Also, the area that makes contact with the timing cover seal seems fine. Final question, has anyone seen a crank pulley rusted enough to be "unbalanced"?

Thanks. Dave

you should be able to use a speedy sleeve on that. just find a bearing house and take the pulley, and seal to them and they should be able to get you the speedy sleeve.The rust shouldn't make it out of balance.

99177 is the wear sleeve part number...same as the parking brake drum on the one-piece transfer case...


I do not know if the balancer being rusted could cause what you see here Dave, but I do know that Jim VanDeVen had a cracked crankshaft that caused the front balancer to carve out the new seal and destroy the front balancer/cover housing in very short order....

Thanks Steve. It looked like someone forced the crank pulley through the timing cover after the cover had been torqued and it(the pulley) was pressing against the inner ring of the timing cover. I will get a picture tomorrow. As far as the pulley goes, I think I have a line on a used one. The sleeve is tempting, but honestly there is some serious rust delamination going-on inside the center of the pulley. A blaster might not be able to reach and a chemical strip will be more than it is worth vs. the used one.
