OPS 45 Crank inspection

Recommended Posts

The balance on the crank seems good.

So far I have run nearly a gallon through the OPS 45.

  The engine is bolted to the mount with aluminum 6-32 screws. Have not had one break.

Did they upgrade the brass flywheel collet to steel?  

IIRC the brass one would mush out causing the flywheel to loosen which in turn made a mess...:(
