Caterpillar TM CAT 130G MIL: Preventive Maintenance Checks

Always perform PMCS in the same order. With experience, you should be able to identify problems easily. If the machine does not perform as required, refer to the appropriate troubleshooting index (WP 0010 00). If anything looks wrong and you can't fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find something seriously wrong, IMMEDIATELY report it to your supervisor.

Before performing preventive maintenance, read all the checks required for the applicable interval and prepare every- thing needed to make all the checks. For example, you'll always need a rag (Item 15, WP 0022 00) or two.

Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in well-ventilated areas. Keep away from open flames and other sources of ignition. Failure to do so may cause injury or death to personnel.

Procedures:

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 solvent cleaning compound (Item 2, WP 0022 00) on all metal surfaces. Use detergent (Item 4, WP 0022 00) and water when you clean rubber, plastic, and painted surfaces.
Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of in accordance with local policy and ordinances.
Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean and apply a light coat of lubricating oil (Item 12, WP 0022 00). Report it to your supervisor.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness and missing, bent, or broken condition. You can't try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If you find one you think is loose, tighten it.
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.
Electric 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 condition.
Hoses and Fluid Lines. 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 can also mean a leak. If a leak comes from a loose fit- ting 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 your machine. The following are definitions of the types/classes of leakage you need to know to be able to determine the status of your machine. Learn and be familiar with them, and remember - when in doubt, notify your supervisor.

CAUTION! Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY YOUR SUPERVI- SOR. When operating with Class I or Class II leaks, check fluid levels more frequently. Class III leaks must be reported immediately to your supervisor. Failure to do this will result in damage to machine and/or com- ponents.

NOTE! Notify Unit Maintenance of any leaks the operator cannot fix.

NOTE • Lubrication instructions contained in this PMCS are mandatory. • Overall views of lubrications points are located at the end of this work package. • Refer to FM 9-207 for lubrication in arctic operation.

GENERAL LUBRICATION PROCEDURES

Included in this PMCS are lubrication services to be performed by the operator.
Lubrication intervals are based on normal operation. Lubricate more during constant use and less during inactive periods. Use correct grade of lubricant for seasonal temperature expected (Refer to KEY on page 0012 00-4).
For equipment under manufacturer’s warranty, hardtime intervals shall be followed. Shorten intervals if lubricants are known to be contaminated or if operation is under adverse conditions (e.g., longer than usual operating hours, extended idling periods, extreme dust, etc.).
Keep all lubricants in an environmental storage 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. Clean top of container before opening.
Clean area around lubrication points with solvent cleaning compound (Item 2, WP 0022 00) or equivalent before lubricating equipment. Keep all external parts of equipment not requiring lubrication free of lubricants. After lubrication, wipe off excess lubricant to prevent accumulation of foreign matter.
Maintain a record of lubrication performed and report any problems noted during lubrication. Refer to DA PAM 738-750 for forms and procedures to record and report any findings.

Before performing preventive maintenance, read all the checks required for the applicable interval and prepare every- thing needed to make all the checks. For example, you'll always need a rag (Item 15, WP 0022 00) or two.
