MAINTENANCE
Item 11 – Vibration Damper
The viscous vibration damper should
be inspected periodically and replaced
if dented or leaking. See Figure 30.
1. Vibration Damper
Figure 30 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.

no cause for alarm.
NOTE:
More severe leaks, combined with a
continual loss of oil, must be corrected
without delay.
2. Visually inspect all lines and
hoses. Listen for any sound of
leaking. Make sure all pipes and
hoses are undamaged, correctly
positioned to avoid chafing, and
properly secured.
