PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION

TM 9-2815-225-34&P · Work Package 0005 00

SCOPE

This Work Package (WP) explains the content and format of the Unit Level PMCS Instructions table contained in WP 0006 00. Also included in this WP are PMCS and lubrication guidelines that should be reviewed before performing any PMCS procedures.

EXPLANATION OF PMCS TABLE

Item Number Column. Numbers in this column are for reference. When completing DA Form 2404 (Equipment Inspection and Maintenance Worksheet), include the item number for the check/service indicating a fault. Item numbers also indicate the order in which you must perform checks and services for the interval listed.

Interval Column. This column tells you when you must perform each procedure in each Procedure column. Before—procedures must be done immediately before you operate the vehicle. During—procedures must be done while you are operating the vehicle. After—procedures must be done immediately after you have operated the vehicle. Weekly—procedures must be done once each week. Monthly—procedures must be done once each month.

Item to Inspect/Service Column. This column provides the location and item to be checked or serviced and manhours to complete task.

Procedure Column. This column identifies the procedure you must perform to check or service the item listed in the Item to Inspect/Service column. You must perform the procedure at the time stated in the interval column.

Equipment Not Ready/Available If: Column. Information in this column tells you what faults keep your equipment from being capable of performing its primary mission. If checks or service procedures show faults listed in this column, the equipment is not mission-capable. Follow standard operating procedures for maintaining the equipment or reporting equipment failure.

PMCS GUIDELINES

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. Always perform PMCS in the same order so it becomes a habit. Once you’ve had some practice, you should be able to spot problems in a hurry. If the vehicle does not perform as required, refer to the appropriate troubleshooting procedure in WP 0004 00. If anything looks wrong and you can’t fix it, write it on your DA Form 2404. If you find something seriously wrong, IMMEDIATELY report it to your supervisor. Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean as you work and as needed. Use detergent (Item 34, WP 0060 00) and water when you clean metal, rubber, plastic, and painted surfaces. Rust and Corrosion. Inspect metal parts for rust and corrosion. If any bare metal or corrosion exists, clean and apply a light coat of lubricating oil (Item 16, WP 0060 00) and report it to your supervisor. Bolts, Nuts, and Screws. Inspect bolts, nuts, and screws for obvious looseness and missing, bent, or broken condition. Inspect for chipped paint, bare metal, or rust around bolt heads. If you find one you think is loose, tighten it. Welds. Inspect for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld, report it to your supervisor. Electric Wires and Connectors. Inspect for cracked, chafed, or broken insulation, bare wires, and loose or broken connectors. Tighten loose connectors and ensure that the wires are in good condition. Hoses and Fluid Lines. Inspect 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 can also mean a leak. If a leak comes from a loose fitting or connector, tighten it. If something is broken or worn out, report it to your supervisor. Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of the engine. Following are types/classes of leakage you need to know to be able to determine the status of your truck. Learn these leakage definitions and remember: when in doubt, notify your supervisor.

Leakage Definitions for PMCS Class I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops. Class II Leakage of fluid great enough to form drops, but not enough to cause drops to drip from item being checked/inspected. Class III Leakage of fluid great enough to form drops that fall from item being checked/inspected.

LUBRICATION GUIDELINES

1. These instructions are mandatory.

2. This equipment is enrolled in the Army Oil Analysis Program (AOAP). Engine oil and transmission oil must be sampled every 90 days as prescribed by DA PAM 738-750.

3. Engines must receive lubrication with approved lubricants at recommended intervals in order to be mission-ready at all times.

4. Recommended intervals are based on normal conditions of operation, temperature, and humidity. When operating under extreme conditions, lubricants should be changed more frequently. When in doubt, notify your supervisor.

SPECIFIC LUBRICATION INSTRUCTIONS

1. Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat. Keep container covers clean and do not allow dust, dirt, or other foreign material to mix with lubricants. Keep lubrication equipment clean and ready for use.

2. Maintain a record of lubrication performed and report any problems noted during lubrication. Refer to DA PAM 738-750 for maintenance forms and procedures to record and report any findings.

3. Keep all external parts of equipment not requiring lubrication free of lubricants. After lubrication, wipe off excess lubricant to prevent accumulation of foreign matter.

4. Refer to FM 9-207 for lubrication instructions in cold weather.
