4-2 MAINTENANCE PROCEDURES

4-2.1 Repair Parts
Repair parts are illustrated and listed in a
separate parts manual. Replacement of parts due
to wear is determined by examination and meas-
urement in the Maintenance Procedures of the
section.
4-2.2 Tools and Equipment
Tools, equipment, and personnel normally
found in a facility capable of making truck repairs
will be adequate for maintenance of the semitrailer.
No other special tools or equipment should be nec-
essary.
4-2.3 Torque Values
Tables 2-1 and 2-2 lists torque values for
standard hardware and is intended as a guide for
average applications involving typical stresses and
mechanical surfaces. Values are based on the
physical limitations of clean, plated, and lubricated
hardware. In all cases, when an individual torque
value is specified, it takes priority over values
given in this table. Replace original fasteners with
hardware of equal grade. Table 2-1 illustrates the
markings on the heads of steel bolts and screws
that indicate their ASTM and SAE grades.
4-2.4 Cleaning
WARNING
1. PAINT THINNER AND OTHER SOL-
VENTS ARE FLAMMABLE AND TOXIC
TO EYES, SKIN, AND RESPIRATORY
TRACT. AVOID SKIN AND EYE CON-
TACT. GOOD GENERAL VENTILATION
IS NORMALLY ADEQUATE. KEEP
AWAY FROM OPEN FLAMES OR
OTHER COMBUSTIBLE ITEMS.

a. Wash semitrailer to remove all accumulated
dirt and grime. For washing aluminum use
water and a mild, non-abrasive soap or deter-
gent such as those recommended for auto-
motive finishes; or a non-etching, non-
abrasive aluminum cleaner. Use a soft cloth
or sponge. Rinse with clear water and dry
with a chamois or cloth to prevent spotting or
streaking. Wax with a liquid or paste wax rec-
ommended for the care of automotive fin-
ishes. Wax should be applied every three to
six months or more frequently if exposed to
extreme weather.
b. Clean the sliding surfaces with solvent or
mineral spirits every six months or more fre-
quently if exposed to extreme dirt or weather
conditions. The slide wear strips are impreg-
nated with a special lubricant, however, addi-
tional lubrication may be required to prevent
chattering or squealing. See Lubrication
Points and Specifications in Figure 4-1
and Table 4-1.
c. After disassembling any components, thor-
oughly clean dirt and old lubricant from all
parts. Do not use a wire brush on any bearing
parts or surfaces — use a stiff bristle brush.
Do not use compressed air, or spin bearing
parts when cleaning. These practices can
throw solvents, dirt, or metal particles into
your eyes. Dry clean
clean, soft, absorbent, cloth or paper. Wash
and dry hands.
d. Replace any missing or illegible decals. Re-
place any missing or damaged reflective tape.
e. Use Troubleshooting Guide to check for
"SYMPTOMS" AND "PROBLEMS" of any
semitrailer system not functioning correctly, or
where wear distortion, or breakage can be
found. Administer "REMEDY" according to
right-hand column of Troubleshooting Guide
(See Section 5).
f. Inspect seals, seal wiping surfaces, bearing
caps, and bearing cones for wear, pitting,
chipping, or other damage.
