 (1)  
Make sure the airplane is in the configuration from the Prepare for the Power Plant Removal procedure.

 S 234-052-N00

 (2)  
Get new vertical tension bolts (1, 2, and 12) or ones which are examined (Fig. 411).

 (a)  
Do a fluorescent penetrant inspection of the vertical tension bolts (1, 2, and 12) (AMM 70-31-01/201).

 (b)  
Examine the threads of the vertical tension bolts (1, 2, and 12) to make sure you can apply a satisfactory locking torque when used with a satisfactory nut.

 (c)  
Discard all vertical tension bolts (1, 2, and 12) with damage which you can feel with a fingernail or thread damage you can see.

 S 644-103-N00
 (3)  
Apply the antiseize compound to the threads and the shanks of the vertical tension bolts (1, 2, and 12) (Fig. 411).

 S 214-104-N00

 (4)  
Make sure you can tighten the self-locking torque of the barrel nuts (5) to a minimum of 70 pound-inches (7.9 newton-meters) (Fig. 411).

 (a)  If the barrel nut cannot hold the minimum torque, replace and examine again the self-locking torque.
 S 214-178-N00
 (5)  
Make sure you can tighten the self-locking torque of the nuts (9) to a minimum of 70 pound-inches (7.9 newton-meters) (Fig. 411).

 (a)  If the nut cannot hold the minimum torque, replace and examine again the self-locking torque.

 (6)  
Examine the engine mounts (AMM 71-21-00/601).
