Preventative Maintenance (PMCS) of Tactical vehicles (HMMVEE)
Standard – Soldiers will learn how to properly PMCS any HMVWEE Vehicle with no supervision before any operations involving any HMMVEE
Condition – Class room settings with power point presentation and lecture.

Preventative Maintenance (PMCS) of Tactical vehicle (HMMVEE)
PMCS (Preventative Maintenance Check and Services)- Thorough inspection of any tactical vehicle prior and
after operating any tactical vehicles. - Failure to conduct PMCS of vehicles can lead to dire
consequences.

1.) Leaks
HUMVEE1.) Leaks - Check both front and side exterior for any leaks. Any leaks detected must be further investigated before further continuation of PMCS. Check underneath for any evidence as well.

Examples

Types of leaks
The amount of leakage is designated by three categories of leaks.Class 1 – Leakage indicated by wetness or discoloration, not great enough to form drops.Class 2 – Leakage great enough to form drops, but not enough to cause drip from item being checked/inspected.Class 3 – Leakage great enough to form drops that fall from the item being checked/inspected

CAUTION
Operating the HUMVEE is allowable only with class 1 or 2 leakage except for the brake system. However, more frequent checks must be made!
WHEN IN DOUT, NOTIFY YOUR SUPERVISOR

2.) Tires
• Check tires for any underinflated (less than the recommended tire pressure).

2) Tires
It will during tire inspections that any brake fluid leaks will be visible. Always check underneath the tire and behind it (under the vehicle).

2.) Tires
Check tire thread depth. Tread should not be worn beyond level of wear bar (1/16 in)

2.) Tires
Check for missing or loose wheel stud nuts and lug nuts. Tighten loose lug nuts and have unit maintenance tighten stud nuts to proper torque.
