FIELD TROUBLESHOOTING PROCEDURES
This work package contains field level troubleshooting procedures for detecting, isolating, and correcting
equipment malfunctions and failures on the M917 Dump Truck Body.
Each troubleshooting procedure lists a fault symptom describing a specific problem. Under each symptom is a
list of possible malfunctions in the order of probability that may be the cause of the problem. Finally, a
corrective action is provided for each malfunction followed by a work package or instruction to notify your
supervisor to correct the problem.
Prior to performing any troubleshooting procedure, the following recommendations must be observed.
This manual cannot list all possible malfunctions that may occur,
nor all tests or inspection and corrective actions. If the symptom for
a particular problem or malfunction is not listed in this work
package, notify your supervisor.

action without proof of a fault wastes time and increases the maintainability of the equipment.
