INTRODUCTION TO TROUBLESHOOTING
WARNING
Failure to perform preliminary inspection on a deadlined boat may
result in injury to personnel and/or damage to equipment.
NOTE
If corrective action provided does not correct malfunction, notify
your supervisor.
This chapter provides the necessary troubleshooting procedures to diagnose mechanical, electrical, and
hydraulic malfunctions for the MK II-S Bridge Erection Boat (BEB). The troubleshooting procedures may
not correct all boat malfunctions encountered. However, the procedures provide a step-by-step approach
that directs tests and inspections toward the source of a problem.
Use the Troubleshooting Index Work Package (WP 0005 00) to identify malfunctions and locate the
troubleshooting procedure needed to diagnose a problem. This manual lists the most common malfunctions
that may occur. If a malfunction occurs that is not listed in the Troubleshooting Index, WP 0005 00, notify
your supervisor.
Each troubleshooting procedure lists a description of the malfunction followed by a step or sequence of
steps to check the operation of a component. Then, in the order of probability, substeps instruct the user to
perform a check, inspection, or test to determine if a condition exists. Each substep includes the corrective
action required to correct the malfunction.
Prior to performing any troubleshooting procedure observe the following recommendations:
1.
Check the Equipment Inspection and Maintenance Worksheet, DA Form 2404, and Maintenance
Request Form, DA Form 2407 (DA Form 5988-E and DA Form 5990-E Automated) to find out why the
equipment has been deadlined. Note the operator's written description of the problem and, whenever
possible, discuss the problem with the operator. This can save time and effort in diagnosing the
problem.
2.
Do not assume the operator's diagnosis is correct, even if it sounds accurate. Always perform the
appropriate troubleshooting procedure(s) to verify the cause of the problem. Performing a corrective
action without proof of a fault wastes time and increases the maintenance of the equipment.
3.
First isolate the system where the malfunction occurs, then locate the component and perform the
corrective action in the ordered listed.
4.
Use approved mechanical, electrical, and hydraulic system repair practices provided in the technical
manuals, field manuals, and technical bulletins listed in WP 0168 00 of this manual.
5.
Use approved special tools and test equipment to determine the known parameters for isolating a
fault.
Fill out an Exchange Tag, DA Form 2402, and attach it to any component that will be exchanged as a core
and turned in for repair or rebuilding at the field or sustainment maintenance level.
