www.mcmaster.com/ for left hand jamb nuts and drill the second one on crank and the crank for safety wire. This is for IF and only IF you do the 2 part hub.




Is there a minimum diameter where if become unsafe to use safety wire? I would think that if the hub did loosen it would be apparent before it became a safety issue, maybe not. Opinions?

Gee how about canning the crank and having a spare flywheel? NIB Echo Trimmer or Blower Short Block No Reserve!! 8 shipping and currently under 25 bid.
