(a)
Include the interior of the fuse pins or bolts, and the inner diameter of the fitting bushings.
(b)
Do these steps if you find corrosion: 1) To remove the corrosion, refer to CPM 54-40-37, Part 3. 2) To repair or replace the corroded part, refer to

(2) Make sure all bushings at the installation points are sealed from corrosion.
(a) If some of the bushings are not sealed, apply sealant to the bushings (AMM 51-31-00/201). 1) Apply a fillet seal to the flanged end of all bushings. 2) Apply sealant (maximum thickness 0.010 inch) to all
unflanged bushing ends which are open to corrosion after the pins/bolts are assembled.
NOTE: No seal is necessary for unflanged bushing ends
____ which are closed to corrosion after the pins/bolts are installed.
a) Do not include the upper link or the diagonal brace. 3) Apply sealant to the bushing ends, that do not have flanges, at the diagonal brace wing fitting.

Do a check of the self-locking torque of the locknut.
1) If the self-locking torque is not 90-800 pound-inches (10.3-91.2 N.m), replace the locknut and do the check again.
NOTE: The torque wrench must be installed on the nut
____ and not the head of the bolt. The C54003 socket can be used to hold the fuse pin while tightening the nut.
Tighten the locknut to 1000-1200 pound-inches (114.0-136.8
N.m).
Install the cap, bolt, nut, and two washers:
1) Apply a thin layer of grease on the contact surfaces of the
cap, two washers, and bolt. 2) Assemble the cap, two washers, bolt, and nut. 3) Tighten the nut to 150-350 pound-inches (17.1-39.9 N.m). 4) Install the cotter pin.
a) If it is necessary, you can loosen the nut a minimum quantity to install the cotter pin.
5) Apply sealant approximately 0.10 inch (2.54 mm) thick, to the two ends of the cotter pin, to prevent movement of the cotter pin.
