The crankshaft timing gear is mounted to the crankshaft, underneath the accessory belt pulley. When the crankshaft is in rotation, the gear drives the toothed belt for timing to ensure the camshafts move in rotation with the crankshaft. If you're crankshaft gear is damaged, it can cause incorrect timing and driveability issues. Replace yours to keep your engine running strong.
