Not sure if I can explain this correct LOL... I got a free ZR 580 EFI... It dropped a piston skirt, crank lobes picked it up and blew skirt chunk out the bottom of the Mag side. Got another good case off ebay, rebuilt ENTIRE ENGINE. I put a dial indicator on the PTO side of orig crank, it was true. So I built the engine. Once I was done I got thinking.... If the crank pressed pins slip the crank lobes off a bit, (not welded Crank) would the crank still be true on dial indicator? But crank still is BAD that I used. in other words if the lobes on a crank pin moved would the dial indicator still say it is true at PTO side?
