While replacing the rear main oil seal on an NAA I noticed that I should be planning on turning the crankshaft and replacing the bearings.
Trying to figure if my crankshaft has been ground down I looked at the numbers on the rear main bearing. It doesn't state any size but has the following info: "Clevite 77 7 79 MB 1501 P".
Can anyone tell me if this is STD, .010, .020, etc?
Thanks, Steve.
