Well that helps. This is probably an original ’57 flywheel. No "Q" stamped in, and for that matter, no notches for emergency rope starting. The cracks are physical metal breaks, not just hairline cracks.
I suspect removal of the flywheel over the years for service has eventually caused failure, but who knows. There is basically a triangular ‘chunk’ that is cracked connecting all 3 puller orifices; and it’s a good thing the motor was not attempted for service prior to being brought to me by the customer. It’s bad enough where you can basically SEE into the cracks, so it’s ready to let loose. The puller orifices are pretty well stripped out too.
I’m just glad the puller was able to get it to pop off the crank before it completely failed! Had that happen before once! Motor has 120/120, and everything else appears to be in good working order otherwise! (just needs the points cleaned/re-synced)
