PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
Preventive Maintenance Checks and Services (PMCS) are performed to keep the engine in operating condition.
The checks are used to find, correct or report problems.
Do "Hourly PMCS" at the designated hours. If equipment has not been operated for the prescribed hours, do the
Do "Monthly PMCS" once a month.
If you find something wrong when performing PMCS, fix it, if you can, using troubleshooting procedures and/or
The right-hand column of the PMCS table lists conditions that make the equipment not fully mission capable.
Write up items not fixed on DA Form 2404 for your support maintenance personnel. For further information on
how to use this form, see Department of the Army (DA) DA PAM 750-8, The Army Maintenance Management
System (TAMMS) Users Manual.
Look for signs of a problem or trouble. Senses help. You can feel, smell, hear or see many problems. Be alert
when operating the equipment.
Inspect to see if items are in good condition. Are they correctly assembled, stowed, secured, excessively worn,
leaking, corroded or properly lubricated? Correct any problems found or notify your supervisor.
There are some common items to check all over the equipment. These include the following:
Bolts, clamps, nuts, and screws: Continuously check for looseness. Look for chipped paint, bare metal,
rust or corrosion around bolt and screw heads and nuts: Tighten them when you find them loose.
Chipped paint, bar metal, rust or corrosion around bolt, screw head and nuts. Clean and repair/repaint as
Welds: Many items on the equipment are welded. To check these welds, look for chipped paint, rust,
corrosion or gaps.
Electrical wires, connectors, and harnesses: Tighten loose connectors. Look for cracked or broken
insulation, bare wires, and broken connectors.
Hoses and fluid lines: Look for wear, damage, and leaks and make sure clamps and fittings are tight. Wet
spots mean a leak. A stain by a fitting or connector can also mean a leak.
LUBRICATION SERVICE INTERVALS - NORMAL CONDITIONS
For safer, more trouble free operations, make sure that your equipment is serviced when it needs it. For the
proper lubrication and service intervals, see PMCS table (WP 0028).
LUBRICATION SERVICE INTERVALS - UNUSUAL CONDITIONS
Your equipment will require extra service and care when you operate under unusual conditions. High or low
temperatures or long periods of hard use in salt water will break down lubricants, requiring you to add or change
