Mike and Richard.
I have two crankshafts at the engine shop tagged red and yellow
Red measures 2.110" to 2.114" Yellow measures 2.112" to 123"
My book (probably the same as Richard's) says -015" and -030 shells are available.
Jeff the reconditioner thinks the two shafts have been ground but????
He needs to grind the best one down another 0.010"
I have a rusted block here that still had the crankshaft installed. It has a reconditioning brass tag that states Pistons +0.020" Big ends -0.015 Mains -0.015
The tag says B&W was the workshop and the date Feb 1945
We still don't know what the original size should be which was my original query.
Who is good with the math?
