Timing Chain – GM (12694716)

Timing Chain transmits drive at a fixed ratio and is matched to its shaft by tooth count and spline. A single tooth difference changes the ratio and surfaces as a speedometer error or a shift complaint.

Replace the Timing Chain when tooth faces show pitting, when a whine rises with road speed, or when there is metal in the fluid. Gears wear as a set, so replacing half of one usually brings the noise back.

Ordering reference for the Timing Chain is part number 12694716, categorised under Camshafts & Timing. Match that number against the component you are removing before you order.

This is genuine GM stock, supplied for the Timing Chain with the manufacturer number intact so the reference on the box matches the catalogue.
