I would double check your mechanics manual to make sure your tolerances are right. You can email mike@kaiserwillys.com too for help.

Questions: Could the mains and rod bearings on the crank be reground to different sizes? I took the crank out and the mains are stamped at 0.10 and the rod bearings are stamped 0.20.
Question By: Henry on Oct 1 2014 12:00 AM
Yes, main bearing and rod bearing sizes can be different. They dont have any connection with one another.
