Camshaft Timing Chains Assembly Overview
Camshaft Timing Chains Assembly Overview
• Crankshaft and camshafts must only be rotated when chain drive is installed completely. Otherwise the valves run into the pistons and the valves or piston heads could be damaged.
• Before removing camshaft timing chain, mark direction of travel with paint. Reversing the rotation direction of a used chain can destroy it.
