6329 motor

Anonymous-0 · Mar 21, 2013

Someone rebuilt this engine with a Deere kit and ran it for a half hour for the break in period. It started making noise so they shut it down. I took the engine apart and found number one piston hitting the head. The rod bushings are good and it plastiguage at .003. The piston measures .009 above the block and so does number six and that did not hit. Any suggestion why? This is in a straw chopper.

Maybe the wrist pin bushing split and it climbed on the other half???

Or a poor job on re-sizing the rod after new bushings were put in...

This motor was rebuilt because the guy said it smoked real bad but all it needed was an injection pump. It only has just over 3000 hours. The rod bushings were not replaced and they haven't spun. The holes line up with with the rod and bushing.
