GENERAL PMCS PROCEDURES
Prior to the performance of the monthly PMCS checks and services,
ensure the fifth wheel towing device is placed into the hydraulic oil fill
to accommodate particular steps being performed.
1. Always perform PMCS in the same order so it gets to be a habit. Once you've had some practice,
you'll spot anything wrong in a hurry. If the fifth wheel towing device does not perform as required,
refer to the appropriate troubleshooting procedure in WP 0024.
2. If anything looks wrong and you can't fix it, write it on your DA Form 5988. If you find something
seriously wrong, IMMEDIATELY report it to your supervisor.
3. Before performing preventive maintenance, read all the checks required for the applicable interval
and prepare all the tools you need to make all the checks. You'll always need a rag (Item 10,
a. Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious

Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing,
bent, or broken condition. You can't try them all with a tool, of course, but look for chipped
paint, bare metal, or rust around bolt heads. If you find one you think is loose, report it to your
d. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you
find a bad weld, report it to your supervisor.
e. Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and
loose or broken connectors. Tighten loose connectors and ensure that the wires are in good
Hoses. Look for wear, damage, and signs of leaks. Ensure that clamps and fittings are tight.
Wet spots indicate leaks, but a stain around a fitting or connector may also indicate a leak. If a
leak comes from a loose fitting or connector, tighten. If something is broken or worn out,
report it to your supervisor.
