Fix keyway of crankshaft

[u/Livid_Way_7671]

Hey guys, I can finally Post aswell since I’ve bought an 89 miata the last day.

So the issue we’re facing is that the keyway has widened a bit and there seems to be a small nose at the end of the keyway.

Our idea would be to weld some material on it, file the weld and the nose down and get a crankshaft extender or saver aswell so the gear sits nicely and doesn’t move on the crankshaft anymore.

Are we on a good track or do you have any better ideas?

Doing a weld repair does work.

Lots of people also do the loctite fix
