MAINTENANCE
Once the initial measurements/ad-
justments have been made, any
adjustments beyond this point should
be made only as required to maintain
satisfactory engine performance.
Item 27 – Vibration Damper
The viscous vibration damper should
be inspected periodically and replaced
if dented or leaking. See Figure 21.
Figure 21
Viscous Vibration
Damper
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 the viscous vibration
damper must be replaced at time
of normal major engine overhaul,
regardless of apparent condition.
