3400 Crank pulley key?

[SHOoff]

Anyone happen to know right off hand what size of key is in the crank on a 3400? I'm going to change out my crank pulley and figured I'll need a new key as well.

Also, any special tool to take it off? Will the little tools at AutoZone/Advance do the job?

thanks!

I've never needed to replace the woodruf key, on any engine I have removed the crank pulley from.

The only reason to replace it would be due to being lost, or severe damage, that you would already know about. lol
