4-2 MAINTENANCE PROCEDURES
4-2.1
Tools and Equipment
. Tools, equip-
ment, and personnel normally found in a fa-
cility capable of making truck repairs will be
adequate for maintenance of the semitrailer.
No other special tools or equipment should
be necessary.
4-2.2
Standard Torque Values. Tables 2-1
and 2-2
lists torque values for standard hard-
ware 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. Re-
place original fasteners with hardware of
equal grade.
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
AWAY FROM OPEN FLAMES OR
OTHER COMBUSTIBLE ITEMS.
4-2.3
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 semitrailer. Rinse degreasing so-
lution off with cold water.
c.
Inspect semitrailer for cause of any reported
troubles.
d.
Scrape, sand, prime, and repaint areas
where finish is missing or where there is evi-
dence of corrosion.
e.
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.
f.
Inspect seals, seal wiping surfaces, bearing
caps, and bearing cones for wear, pitting,
chipping, or other damage.
4-3 HITCH, FRAME, AND DECK
4-3.1
Repairing Structural Defects
If any structural defect is found, the fault must
be corrected before further use of the vehicle. To
continue usage could endanger the semitrailer, its
load, personnel, traffic, and properties. Inspect the
deck daily for broken or missing planks or missing
attachments. Replace any defective parts promptly.
