NOTE: If equipped, the diamond washer should be cleaned and inspected for any damage. If damage is evident, replace the diamond washer. If no damage, the diamond washer is to be reused. If the diamond washer is not installed, engine damage may occur.

NOTE: Early build engines are equipped with a diamond washer on each side of the crankshaft sprocket. Late build engines have a laser etched crankshaft sprocket and do NOT require diamond washers. If an early build engine requires crankshaft sprocket replacement, discard the diamond washers and the sprocket and install a new laser etched sprocket (service part). Diamond washers should NEVER be installed with the laser etched sprocket.

If equipped, install the diamond washer.
