Default Bent the timing guide pin for the crankshaft pulley

So tonight I was tightening the crankshaft bolt and didn't put the plate behind the bolt itself and tightened the bolt down to torque specs and then realized that I messed up to late. My question what is that party called or how do I unbend it ?

It's called a woodruff key. Replace it.

Only Fae in his sawzall days would be stupid enough to try to reuse it.

It's pretty cheap from Mazda. When I did mine I don't think I was able to find the same size key stock at the hardware store.

You can buy keystock in just about any size from places like McMaster-Carr.

It is the crank woodruf key. At least that is what mazda calls it. It is very much not a woodruf key at all. They are like $6 at a dealer.

yep, it needs to have the same radius ground into it as the cutout on the crank.
