In rebuilding a 140 engine, we got the crank out last night. The mains have stamped on them: Fm HH.002 U.S., below that 360223R1(a part number?) then below that 74 H24. 1.Would I be correct in assuming that the crank has been turned one time? The bearings do not look scarred, however the tractor could not maintain good oil pressure when it was running. I'm planning on taking the crank, block, and head(new valves ect.) to the machine shop to be checked. 2. Will the crank need to be turned again or can the same size bearings be used? Thanks for any imput.
