Alright, I bought the crank-locking timing tool and cam bar to replace the snapped timing belt.
The crank pin is just not working out.
1) It went into place at top dead center, but didn't prevent the crank from turning when I put any torque on it.
2) Now it won't come back out. I've been trying to get pliers and vice grips on it, but it's just about impossible in the position it's in.
So... anyone have any tips on that? Is there some way to get pieces back out if I somehow just have to break it?
