Section III. DIRECT SUPPORT AND GENERAL SUPPORT MAINTENANCE PROCEDURES

This section will cover Direct Support and General Support Maintenance procedures for the flatrack. All Direct

Support Maintenance procedures are listed first followed by all General Support Maintenance procedures. The

following are general maintenance procedures to keep in mind:

Removal and Disassembly.

(1) Precision matched or mated components, assemblies, subassemblies, or parts (other than common

hardware) should be marked, handled and stored to preclude damage and to ensure reassembly and installation in

their matched positions.

(2) Do not separate bonded, press-fitted, soldered, welded, or riveted parts unless such removal is necessary to

clean, inspect, or test that part separately.

Inspection.

(1)

Inspect for loose, missing or damaged parts.

(2)

Check for cracks, rust or pits, especially at weld points.

(3)

Inspect all parts to determine if they conform to the wear limits, fits and tolerances established.

c. Lubrication. General lubrication needed before assembly or installation is called out in the maintenance

procedures.

Assembly.

(1)

Refer to notes or diagram made during disassembly to install precision matched or mated parts.

(2)

Check and record shimming requirements as applicable.

(3)

Torque bolts and nuts as noted in the maintenance procedure.

e. Testing. If needed, test procedures to verify proper operation will be called out in the maintenance procedure.

Perform testing as it is listed.

Installation.

(1) Perform alignment and adjustment procedures as listed in the maintenance procedure. Complete any

testing required before the flatrack is returned to operation.
