My woodruff key is mangled. The depression where on the crankshaft is distorted as is the slot on the inside of the flywheel. A machinest I spoke with said I can get by without one because it is the flywheel taper and bolt that holds everything in place. The woodruff key is just for aligning the timing. That didn't sound right.

if it has a crankshaft position sensor then it will be imperative that you have a key. if the harmonic balance spins you could ruin the crank. if you don't have the key you will not be able to use a timing light. buy a new key get a small file and clean up the slot and braze if needed to make key work

Sounds like your flywheel was loose and relied on the key to hold its position. Clean out the slot and use a new key. As it only aligns it, the taper holds it in position.

That's what the woodruff key is for, aligning the timing. Without it the timing will be off, will change every time the crank turns and the engine, absolutely, will not run. I wouldn't let your machinist work on my grand kids tricycle.

ON WHAT?!?!
If it is tapered you can probably get by without it, BUT if it s a flywheel and timing is cruicial, then you probably should use the woodruff key.

your machinist would be correct. In order to aid in installation some manufactures use dowels or keys to aid you when installing a component. Make sure you use the slot as an index. This is in case the bolt circle is symmetrical,and some flywheels have timing marks or are used to balance the motor. If it is balanced this is a critical factor! I would suggest using some removable loctite (blue) on bolts before installing.
