 G.  Prepare for the Installation
 S 214-008-003
 (1)  Do a check that all attach pins, bolts, caps, and washers at installation points are free from corrosion, including interior of fuse pins or hollow bolts and the inner diameter of fitting bushings.
 (a)  If corrosion exists, either replace part or remove corrosion and apply corrosion protection (CPM Part 3, 54-10-47). 1) Apply two coats of primer to all exposed surfaces,
 including ID bore, but excluding chrome plate OD, if not already primed. 2) Apply a 0.05-inch (1.3 mm) thick coating of corrosion preventive compound to ID of attach pin/bolt.
 S 214-009-003
 (2)  Make sure all the bushings at installation points are sealed from corrosion.
 (a)  If bushings are not sealed, apply sealant to bushings (AMM 51-31-01/201). 1) Apply fillet seal to flange end of all bushings. 2) Brush coat seal (maximum thickness 0.010 inch) to entire
 periphery of all (except upper link wing fitting and diagonal brace wing fitting) unflanged bushing ends exposed to mating surface of parent part.
 NOTE: No seal is required for bushing end not exposed to
____ mating surface of parent part. Corrosion prevention in this area is covered by application of grease during pin or bolt installation.
 3)  Apply fillet seal to entire periphery of unflanged bushing end at diagonal brace wing fitting.
 S 214-010-003
 (3)  Do a check to make sure you have the correct part number fuse pin(s).
