If the roll pin on the crankshaft gear (the one the timing belt rides on)has sheared off, replace that gear and consider replacing the pulley too. You want fresh mounting surfaces and the correct clearance if the pulley spun at all on the face of the the gear. Also the gear has a slight step to it, if that is worn off, replace it.

Good luck extracting that bolt. Its a PITA.
