Checking the Vibration Damper

Checking the Vibration Damper - Ops - DD5/DD8

Check the vibration damper as follows:

  1. Inspect the viscous vibration damper periodically and replace if dented or leaking.
  2. Heat from normal engine operation may, over a period of time, cause the fluid within the damper to break down and lose its dampening properties. For this reason, replace the viscous vibration damper at time of normal major engine overhaul, regardless of apparent condition.
