Maintenance and Lubrication
This section contains instructions necessary for proper
maintenance of the semitrailer. The 900D series
semitrailer is designed for years of service with minimal
maintenance. However, proper maintenance is important
for durability and safe operation and is an owner/user
responsibility.
Maintenance Schedule
Trailer maintenance includes periodic inspection and
lubrication.
Table 4-2, Maintenance Schedule,
lists the
recommended maintenance and lubrication tasks by time
interval and by accumulated mileage (use whichever
occurs first).
Table 4-3, Hydraulic Engine Maintenance
Schedule
, lists the recommended maintenance tasks for
the hydraulic engine package.
DANGER
Inspection
1. Inspect the tractor, the trailer, and trailer parts
periodically for damage or signs of pending failure.
Damaged or broken parts must be repaired or
replaced at once. Determine the cause of any
binding or hydraulic leakage at once. Correct the
problem before using the tractor or trailer.
2. Use
“Troubleshooting Guide” on page 5-1
to
check for “SYMPTOMS” and “PROBLEMS” of any
trailer system not functioning correctly, or where
wear, distortion, or breakage is found. Administer
“REMEDY” according to the right-hand column of the
troubleshooting section.
Lubrication
Figure 4-1 and Table 4-1
detail lubrication points and
intervals, method of application, and lubricant required,
and illustrate the location of each part to be lubricated.
During inspections of the trailer, if lubricants are found to
be fouled with dirt or sand, those parts should be cleaned
with paint thinner, dried, and relubricated immediately.
Dirt in a lubricant forms an abrasive compound that will
wear parts rapidly.
WARNING
Operating the tractor or trailer with defective,
broken or missing parts may result in serious
injury or death, damage to the tractor/trailer, its
cargo, or property in its path.
Paint thinner and other solvents are flammable
and toxic to eyes, the skin, and respiratory tract.
Avoid skin and eye contact. Good general
ventilation is normally adequate. Keep away from
open flames or other combustible items.
