4.6.2 Check and Replace Isolators/Shockmounts

a. Replacement Criteria
CAUTION
Continued operation with failed shock-
mounts may result in engine or generator
damage.
When a shockmount has been cut, split, abraded or has
flared due to normal deterioration, it must be replaced.
Damage to the mounts may not be visible when installed
and under load from the component. To correctly
inspect shockmounts, they must be removed.
b. Engine Isolator/Shockmount Replacement
1. Use the two lift eyes to lift and support the engine.
2. Remove truss, unidrive isolator and all hardware as
shown in Figure 4-9, if equipped.
3. Remove all hardware as shown in Figure 4-10.
4. Raise the engine just enough to remove the shock-
mounts (Figure 4-10 item 4).
5. Install new shockmounts.
NOTE
For torque values refer to paragraph 4.7.
6. Lower the engine enough to assemble hardware as
shown and torque per paragraph 4.7.
