CAUTION

The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove the engine front cover. See -Timing Chain Cover and Seal- in this section.
3. Remove the timing chain tensioner:
   1. Compress the timing chain tensioner and insert a paper clip into the hole.
   2. Remove the bolts and timing chain tensioner.

2. If the camshaft sprockets were not removed, use the flats on the camshafts to prevent camshaft rotation and loosen the sprocket bolts.
3. If removed, install the camshaft sprockets and the bolts. Do not tighten the bolts at this time.
4. Install the LH timing chain guide and bolts. Tighten to 89 inch lbs. (10 Nm).
