CHECKING TIMING CHAIN SLACK

This procedure applies to all models that use a timing chain.

See Figure 9

1. Position a scale (ruler of straightedge) next to the timing chain to detect any movement in the chain.
2. Place a torque wrench and socket on the camshaft sprocket attaching bolt. If the cylinder heads are installed on the engine, apply 30 ft. lbs. (41 Nm). If the heads are removed, apply 15 ft. lbs. (20 Nm) of force to the bolt and rotate the bolt in the direction of crankshaft rotation in order to remove all slack from the chain.

1. While applying torque to the camshaft sprocket bolt, the crankshaft should not be allowed to rotate. It may be necessary to block the crankshaft to prevent its rotation.
2. Position the scale over the edge of a timing chain link and apply an equal amount of torque in the opposite direction. If the movement of the chain exceeds 1 / 8 in. (3mm), replace the chain.
