4.6.2Check and Replace Isolators/Shockmounts a. Replacement Criteria

CAUTION

Continued operation with failed shockmounts 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 4-9.

4.Raise the engine just enough to remove the shockmounts (Figure 4-9 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.

7.Remove chains from the lift eyes.
