Crankshaft Issue Tuesday, September 15, 2009 I got a call from Mike at ABT today. The big end of the crank shaft, the surface that rides inside the rear main seal, is severely pitted. It is a shame too, because the rest of the crank looks very good. This crank cannot be used as-is, so there are a few options: 1. Use a different ’01+ crank, which I do not have 2. Use a 1994-1997 crank, which I do have 3. Sleeve the surface, which may take a while Mike is researching options and I’ve got some homework to do too.
