All vehicles

6. Rotate the belt tensioner clockwise and disconnect the accessory drive belt from the crankshaft pulley.





7. Check the crankshaft vibration damper runout.
- Remove the paint from the face of the crankshaft vibration damper at 4 points 90 degrees apart.

- Attach the Dial Indicator Gauge with Holding Fixture to the cylinder block. Position the Dial Indicator Gauge with Holding Fixture on one of the unpainted surfaces.

- Using a suitable tool, pry the crankshaft forward. Zero the Dial Indicator.

- NOTE: Pry the crankshaft forward only to eliminate possible error caused by crankshaft end play.

Rotate the crankshaft 90 degrees. Pry the crankshaft forward. Record the measurement. Repeat at each unpainted surface.

- If the runout exceeds specification, install a new crankshaft vibration damper.





8. WARNING: Support the vibration damper during mounting bolt removal. The damper can slide off the nose of the crankshaft. Failure to follow this instruction may result in serious personal injury.

Remove the 4 bolts and the crankshaft pulley.
- Discard the bolts.
