The motor came to me that way. I took off the
flywheel and there it was. The shrapnel was gone.
Most likely the result of a loose flywheel.
If in a pinch I suppose I could use it. Its a pretty
common part as well, so I found a replacement.
Possibly your motor had a similar experience.
Operator noticed the flywheel was loose and
tightened it not knowing there was damage. When
you turn the flywheel does it run true or have a
wobble? Another possibility is someone packed
1 cylinder with rope and then used a 24″ braker
bar to tighten the nut. Just speculation but
something occurred that has this flywheel on
tighter than it needed to be. Those of us who have
responded offer our experience , or an opinion
based on our experience. You then need to
determine what seems to be the best approach in
your situation. For me your decision the cut of the
flywheel would be premature. I would be taking
a regular framing (claw) hammer, checking the
tool to see that its tight, and then smacking it as
hard I as I could. I would repeat this till I was
convinced it wasn’t going to work. That’s what
I would do based on what you have posted. If I
was there to see just what you have experienced
or had the motor myself, my approach may be
different. In the end the decision will be yours.
How it turns out will be the experience you will
be able to offer to someone in the future that is
having this same problem.
