4-4. GENERAL PMCS PROCEDURES (Cont.)
While performing specific PMCS procedures, inspect the following components:
Bolts, Nuts, and Screws. Ensure that they are not loose, missing, bent, or broken. Tighten any that
are loose.
Welds. Inspect for gaps where parts are welded together. Check for loose or chipped paint, rust, and
cracks. Report bad welds to Direct Support maintenance.
Electrical Conduit, Wires, and Connectors. Inspect for cracked or broken insulation, bare wires, and
loose or broken connectors. Report loose connections and faulty wiring to your supervisor. Use
dielectric grease on all pins and connectors.
Hose, Lines, and Fittings. Inspect for wear, damage, and leaks. Ens ure that clamps and fittings are
tight. If a component is broken or worn, correct the problem if authorized by the Maintenance Allocation
Chart (MAC) (Appendix B). Report any damage, leaks, or loose fittings and clamps to your supervisor.
Check that components are adequately lubricated in accordance with Appendix C.
4-5. SPECIFIC PMCS PROCEDURES
Unit PMCS is provided in Table 4 1. Always perform PMCS in the order listed. Once it becomes a
habit, anything that is not right can be spotted in a minute. PMCS is a good tool for learning about the
semitrailer. Times to perform good PMCS will decrease as you become more familiar with its
operation.
Before performing PMCS, read all the checks required for the applicable interval and prepare all the
tools needed. Have several clean rags handy. Perform all inspections at the applicable interval.
The column headings in Table 4-1 are defined as follows:
Item No. Provides a logical sequence for PMCS to be performed and is used as a source of item
numbers for the "TM ITEM NO." column when recording PMCS results on DA Form 2404. Item
numbers also appear in the order that you must perform checks and services for the intervals listed.
Interval. Specifies the interval at which PMCS is to be performed.
Item To Check/Service. Lists the system and common name of items that are to be inspected.
Included in this column are specific servicing, inspection, replacement, or adjustment procedures to be
followed.
Procedure. Provides the procedure that must be performed to check or service the item. Carefully
follow these instructions. If you do not have the tools, have Unit maintenance perform the work.
Equipment Not Ready/Available If: Explains when the semitrailer is nonmission-capable.
NOTE
Mission requirements, urgency, safety, and common sense should
be considered in determining NMC status of the semitrailer.
