  1. Looking for crankshaft specs. Specifically the PTO end after sump. Diameter & length. I don’t see that info included in your offerings. It seems to me that the info would be quite pertinent to some folk’s? What say you? As a matter of fact, there appears to be quite a bit of missing specs for the engine I am looking in to? For referance~~KAWASAKI FH541V-CS06. Can I get some help PLEASE?
