Default Re: Rear Main Seal - Help please

You will have to go through all the bearings to check for damage, and to adjust clearances ---
I know that you may not like what you see, I didn't when I first took off my rear cap 3000 miles after a rebuild --it was just crumbs, it only had a little chunk off the thrust too when i first took off the pan.

The crank really needs to be measured accuratly with a micrometer ---a harbor freight digital caliper for 9.95 with coupon can get you close, tell if std, .010, .020 or so with a +- .003 tolerance or so, but an accurate micrometer is best.

Babbitt is made to fit crankshafts, crankshafts are made to fit inserts ---for babbitt a crankshaft can be any size as long as it is straight and round ----but with inserts the crankshaft has to be the exact size for that insert.
