[quote=c32bnz]. Are you supposed to have room to stick your pinky finger in the bolt? quote]

Not sure what you mean but I can feel the head of my bolt easily and it is obviously touching the inside of the pulley.

This bolt should be tightened up to specs and this requires the engine to be stopped from turning. A new bolt is required even if this one is in one piece.

The pulley is on a key and it and the pulley may be damaged. The key may have damaged the crankshaft as well. Not good.
