GENERAL MAINTENANCE INSTRUCTIONS
1. These general maintenance instructions contain general shop practices and specific methods you must
be familiar with to properly maintain your semitrailer. You should read and understand these practices
and methods before performing any organizational maintenance tasks.
2. Before beginning a task, find out how much repair, modification, or replacement is needed to fix the
equipment. Sometimes the reason for equipment failure can be seen right away, and complete
teardown is not necessary. Disassemble equipment only as far as necessary to repair or replace
damaged or broken parts.
3. In some cases, a part may be damaged by removal. If the part appears to be good, and other parts
behind it are not defective, leave it on and continue with the procedure. Here are a few simple rules:
a. Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
b. Do not remove bearings (rollers) or bushings unless damaged. If you need to remove them to
access parts behind, pull bearings (rollers) and bushings out carefully.
c. Replace all gaskets, seals, and preformed packings.
4. The following "Initial Setup" information applies to all procedures:
a. Resources are not listed unless they apply to the procedure.
b. "Personnel Required" is listed only if more than one technician is required to complete the task.
5. All tags and forms attached to equipment must be checked to learn the reason for equipment's removal
from service. Modification Work Orders (MWO) and Technical Bulletins (TB) must also be checked for
equipment changes and updates.
