So if a flywheel key does it set timing then can you do this?

[noob_boater]

drill hole half way or all the way through crankshaft and flywheel (aligning them precisely), tap holes and then screw a grade 8+ bolt to hold both parts together. No more shearing keys..

will it work? if the flywheel and crankshaft ever gets damaged beyond repair, i'm gonna try that..

Re: So if a flywheel key does it set timing then can you do this?

I would assume if that was safe, then it would be done that way. I think the key is designed to shear rather than have the flywheel or crankshaft come apart, doing irreparable damage to the motor in the best case, and possibly sending fast-moving shards of metal whipping around in every direction in the worst case. Somehow I think I would rather replace a sheared key and more importantly figure out why the key sheared in the first place.

I have had a new keyway machined in a crank 180 degrees off from the original, and a new one cut in the flywheel also 180 degrees off from the original in order to same a motor from the scrap heap. The old slots were filled to prevent confusion. A note was etched inside the flywheel.
