4-2 MAINTENANCE PROCEDURES
4-2.1
Standard Torque Values
Table 2-1 and 2-2 lists torque values for stan-
dard hardware and is intended as a guide for aver-
age applications involving typical stresses and me-
chanical surfaces. Values are based on the physi-
cal limitations of clean, plated, and lubricated hard-
ware. 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.
4-2.2
Cleaning
WARNING
PAINT THINNER AND OTHER SOL-
VENTS ARE FLAMMABLE AND TOXIC
TO EYES, SKIN, AND RESPIRATORY

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 trailer, its load,
personnel, traffic, and properties. If any cracks or
breaks are found, contact a Landoll authorized
service center for repairs. Inspect the deck daily for
broken or missing planks or missing attachments.
Replace any defective parts promptly.
4-4
a. Wash trailer 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 trailer 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. Replace any missing or illegible decals. Re-
place any missing or damaged reflective tape.
f. 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.
g. Inspect seals, seal wiping surfaces, bearing
caps, and bearing cones for wear, pitting,
chipping, or other damage.
