Vibration Damper
Visually inspect the damper front cover plate for signs of raising or deforming. If variations are
noted or suspected, proceed as follows:
a. Remove the paint and accumulated dirt and grime from both the front and rear surfaces of
the damper in four equally-spaced areas (avoid the area with stamped lettering); use only a
good paint solvent. This will allow for precise measurement of the damper's thickness.
b. Measure and record the thickness of these four areas approximately 0.125 inch (3.17mm)
from the outside edge of the front cover plate.
c.
Replace the damper if variations of 0.010 inch (0.25 mm) or more are found or if the
thickness exceeds 2.574 inches (65.38 mm) (paragrap 4-12). Evacuate to general support
maintenance.
