FIELD MAINTENANCE
GENERAL REPAIR INSTRUCTIONS
INITIAL SETUP:
Not Applicable
BURRS
Remove burrs from surface teeth with a fine-cut file or cross cloth.
END OF TASK
EXTERIOR PARTS
NOTE
Polished or machined steel parts not protected by cadmium, tin, copper, or other plating or
surface treatments require protection. Bare metal surfaces must be free of moisture when
protective coating is applied.
Chassis and exterior painted parts may be resurfaced when paint is damaged, or where parts have been repaired.
END OF TASK
PROTECTING PARTS
Protect bare steel surfaces from rust when not actually undergoing repair work. Dip parts in, or spray them with
corrosion preventive compound (WP
0193, Table 1, Item 32). Aluminum parts may require protection in atmospheres
having a high salt content.
END OF TASK
SCREWS, NUTS, AND FITTINGS
Replace any screw, nut, or fitting with damaged threads. Inspect tapped holes for thread damage. If cross-threading
is evident, re-tap the hole for the next oversize screw or stud. If the re-tapping will weaken the part, or if the cost of
the part makes re-tapping impractical, replace the part. Chasing threads with proper size tap or die may be adequate.
END OF TASK
STUD INSTALLATION
When installing studs use a proper driver. A worn stud driver may damage the end thread. Then a chasing die must
be used before a nut can be screwed on. This procedure will remove cadmium plating and allow corrosion. Before
installing a stud, inspect the hole for chips. Blow out foreign matter and start stud by hand. Before final insertion,
coat thread with a film of antiseize compound (WP
0193, Table 1, Item 9). Install stud to proper "setting height",
which is the total projecting length.
