Default Crankshaft position. Plz help

I’m in the process of installing an SC kit. I had some issues with my crank shaft and the slot that the woodruff key goes all the way through. It was misaligned somehow. My question is. How critical is this to the cars timing? I’m guessing since I spun the crankshaft, it would be off a bit but I’d love for someone to chime in. I hope it doesn’t matter



Top one was way out of alignment. Second photo was when I got it back properly.

Another thing I’m wondering. Even if the crank moves, I never actually moved the Gear so it theoretically should still be in time, right?

Timing of the motor is critical. However if you just took the crank pulley off, the timing is unchanged. The timing is all crank, cams and chains on the inside of the motor. So as long that is unchanged, timing is unchanged.

omg thanks so much! I was hoping the timing was fine, but I just needed to get a second opinion on it.

Only issue is your external crank timing mark is now slightly off.

It aligns to an external mark on the side of timing cover, to indicate TDC.

So if you ever need to use that mark, it'll be slightly off. But of all the things you'd ever need to use that mark for that I can think of, doing a valve adjustment for example, that level of precision isn't required.

Nothing to worry about here.

Except one. The sc gets driven off that crank pulley. Which means all the torque to drive sc goes through that woodruff key (on top of torque to drive the serp belt and all its accessories).

I didn't quite understand what you described happened. Was that key not aligned in both slots properly? Was key mangled or damaged?

Just think about what that key needs to drive, and consider if whatever happened is enough to cause any concerns here.

you got it right, the key was not aligned with both slots so I had to rotate the crankshaft snout. To get it back in alignment..I was thinking that rotating the crack like that by itself would throw something off

The key is for alignment, it shouldn't be driving anything unless the crank bolt is loose.
