Spun Bearing? Can the case still be used?
matara - June 20th, 2005 at 11:14 AM

I have an old AS41 case that I was given. I opened up the case to find that one of the rods had welded itself to the crank. I believe that this is a result of the rod bearing getting pouded out and then spinning, blocking the journal on the crank and causing massive heat build up due to lack of lubrication. I found bits of the rod bearing in the case (looked like wafer thin bits of flat metal).

I assume the crank and rods are shot, but do you think that the case is shot too? Would the cam, followers and oil pump be shot too with all that metal floating around the oil system? They all look unmarked.

Thanks

Steve

only way to tell is give it to a machinist and get them to mic it out

what he said


you can tell a fair bit by looking at the case closely though, fret marks etc

steve 9 out of 10 times the case will be servicable,you will require a line bore . this will help determine if the case is true at the journals. the stock crank is a tough critter..can also be rescued but at a cost.cheers dsk steve
