POWERTRAiN MOUNTS
Powertrain mounts (Figures 5 and 6) are the
nonadjustable type and seldom require service. Broken
or deteriorated mounts should be replaced
immediately, because of the added strain placed on
other mounts and drive line components.
C h e c k i n g P o w e r t r a i n M o u n t s
Raise the engine to remove weight from the
mounts and to place a slight tension on the rubber.
Observe all mounts while raising engine.
If a powertrain mount exhibits:
a. Hard rubber surface covered with heat
check cracks,
b. Rubber separated from a metal plate of the
mount or,
c. Rubber split through center;
Replace the mount. If there is relative movement
between a metal plate of the mount and its
attaching points, lower the engine on the mounts
