Check the index lines (A) on the damper hub (B) and the inertia member (C). If the lines are more than 1.59 mm
[1/16 inch] out of alignment, replace the damper.
Inspect the vibration damper hub (B) for cracks. Replace the damper if the hub is cracked.
Installation
Inspect the rubber member for deterioration. If pieces of rubber are missing or if the elastic member is more than
3.18 mm [1/8 inch] below the metal surface, replace the damper.
NOTE: Also look for forward movement of the damper ring on the hub. Replace the damper if any movement is detected.
