Chainsaw Repair

I showed Al the 372 bare crankcases I have that  would create a air leak when  both ceramic bearings had spun when the saw would warm up under 3 cuts.  5ci alky saw. I just gave the builder another crankcase  to use.

But like Al and others said they said it was still usable if one of the above ways are used.

Joey mine was outer race to crankcase. Good idea on the sleeve for a different problem. I had to do that on some small block 60's chevy's in the past.
