Timing Chains: Inspection

Inspect components for damage. Inspect friction surfaces on tensioner arms and chain guides for wear. Replace components as necessary.

CAUTION: If timing were changed due to damaged components, ensure crankshaft is rotated so pistons are below deck surface (crankshaft keyway at 90 degrees) to avoid contact with valves. See Figure. Ensure camshaft positioners are installed on camshafts before installing timing chains.
