Position a scale next to timing chain so that any movement of chain may be measured.Position a torque wrench and socket on the camshaft sprocket attaching bolt. Apply force in the direction of crankshaft rotation to take up slack to the following torque:41 N·m (30 ft. lb.) with cylinder heads installed20 N·m (15 ft. lb.) with cylinder heads removedWith torque applied to the camshaft sprocket bolt, crankshaft should not be permitted to move. It may be necessary to block crankshaft to prevent rotation.

Holding a measuring scale along edge of chain links.Apply force in the reverse direction to the following torque:41 N·m (30 ft. lb.) with cylinder heads installed20 N·m (15 ft. lb.) with cylinder heads removedMeasure amount of sprocket/chain movement.Install a new timing chain and sprockets if movement exceeds 3.175 mm (1/8 in.).
