 (2)  Get new vertical tension bolts (1, 2, and 12) or ones which are examined (Fig. 411).
 (a)  
Do the 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 644-087-N00
 (3)  
Apply the antiseize compound to the threads and the shanks of the vertical tension bolts (1, 2, and 12) (Fig. 411).

 S 214-088-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).

 (a)  If the barrel nut (5) cannot hold the minimum torque, replace and examine the self-locking torque again.
 S 214-179-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).
 (a)  If the nut cannot hold the minimum torque, replace and examine the self-locking torque again.
 S 214-089-N00
 (6)  
Examine the engine mounts (AMM 71-21-00/601).

 S 104-158-N00

 (7)  
Make sure the mating surfaces of the forward and aft engine mounts do not have oil, grease, and other unwanted material.

 S 644-090-N00

 (8)  
Apply the antiseize compound to the shear pins on the forward and aft engine mounts (Fig. 411).

 S 214-091-N00

 (9)  
Examine the wire bundles in the support beam for the fan cowl for damage and to make sure they are tight.

 (10)
 If they are installed, open the fan cowl panels (AMM 71-11-04/201).
