Problem- replaced alternator belt after it snapped, all was fine for a couple of days and it snapped again. Upon examination i notice the crankshaft pulley had damaged the lower timing cover. The outer steel ring on the crankshaft pulley has slipped inboard and into the plastic timing belt cover. I removed the pulley and re-position the outer ring, refitted and started engine, all seemed okay. Then i put on new belts and stated engine the outer ring on pulley starte dto slide into timing belt cover again. Is the fault with the pulley or is something causing problem.
TIA chris
