GENERAL.
a. These general maintenance instructions contain general shop practices and specific procedures you must be
familiar with to properly maintain your dump truck.
You should read and understand these practices and procedures
before performing any Direct Support and General Support Maintenance procedures.
b. 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 parts.
c. 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:
(1)
Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
(2)
Do not remove bearings or bushings unless damaged.
If you need to remove them to access parts behind,
pull bearings and bushings out carefully.
(3)
Replace all gaskets, lockwashers, seals, cotter pins, and preformed packings.
d. The following "Initial Setup" information applies to all procedures:
(1)
Resources are not listed unless they apply to the procedure.
(2)
"Personnel Required" is listed only if more than one mechanic is required to complete the task.
e. All tags and forms attached to equipment must be checked to learn the reason for removal of equipment from
service.
Modification Work Orders (MWO) and Technical Bulletins (TB) must also be checked for equipment changes and
updates.
