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 this
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
list torque values for stan-
dard hardware and hydraulic fittings. They are in-
tended as a guide for average applications involv-
ing typical stresses and mechanical surfaces. Val-
ues are based on the physical limitations of clean,
plated, and lubricated hardware. In all cases, when
an individual torque value is specified, it takes pri-
ority over values given in this table. Replace origi-
nal fasteners with hardware of equal grade.
4-2.4
Cleaning
a.
Wash semitrailer to remove all accumulated
dirt and grime.
b.
Use any mineral spirits paint thinner (or its
equivalent) to remove grease and oil from all
parts of the trailer. Rinse degreasing solution
off with cold water.
c.
Inspect semitrailer for cause of any reported
troubles.
WARNING
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
A W A Y F R O M O P E N F L A M E S O R
OTHER COMBUSTIBLE ITEMS.
d.
Scrape, sand, prime, and repaint areas
where finish is missing or where there is evi-
dence of corrosion.
e.
Replace any missing or illegible decals. Re-
place any missing or damaged reflective tape.
f.
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.
g.
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 parts with lint free,
clean, soft, absorbent, cloth or paper. Wash
and dry hands.
h.
Inspect seals, seal wiping surfaces, bearing
caps, and bearing cones for wear, pitting,
chipping, or other damage.
