Vibration Damper - Check
Damage to the damper or failure of the damper will increase vibrations. This will result in damage to the crankshaft.
Replace the damper if the damper is bent or damaged. Replace the damper if the bolt holes are oversize. Replacement of the damper is also needed after a crankshaft failure due to torsional forces.
