SPECIFIC INSPECTION AND SERVICING INSTRUCTIONS

TM 9-2320-280-20-1 2-2 Change 1 2-6. SPECIFIC INSPECTION AND SERVICING INSTRUCTIONS The following steps should be taken while performing specific inspections and services: (1) Do the Semiannual (S) preventive maintenance checks and services listed in Section III in this chapter. (2) Lubricate the vehicle. Do not lubricate gear cases and engine unless processing tag states that the oil is unsuitable for 500 mi (805 km) operation. If oil is suitable, just check level. (3) Schedule semiannual service on DD Form 314 (Preventive Maintenance Schedule and Record Card). (4) If vehicle is delivered with a dry charged battery, activate it according to TM 9-6140-200-14. (5) Check vehicle coolant level and determine if solution is proper for climate (refer to TB 750-651 for preparation of antifreeze solutions). (6) Remove towing brackets from their stowed position behind the bumper and install them in their proper location (para. 9-2, 9-3, or 9-4). (7) Remove front lifting shackles from stowed position under passenger seat and install on towing brackets (para. 9-13). Section III. PREVENTIVE MAINTENANCE CHECKS AND SERVICES 2-7. GENERAL The best way to maintain vehicles covered by this manual is to inspect them on a regular basis so minor faults can be discovered and corrected before they result in serious damage, failure, or injury. All intervals are based on normal operation. Hard time intervals may be shortened if your lubricants are contaminated or if you are operating the equipment under adverse conditions, including longer-than-usual operating hours. Hard time intervals may be extended during periods of low activity, though adequate preservation precautions must be taken. This section contains systematic instructions of inspection, adjustment, lubrication, and correction of vehicle components to avoid costly repairs or major breakdowns. This is Preventive Maintenance Checks and Services (PMCS). 2-8. INTERVALS a. Unit maintenance, assisted by operator/crew, will perform checks and services contained in Table 2-1 at the following intervals: (1) Semiannually (S). Every 6 months or 3,000 miles (4,800 km), whichever comes first. (2) Annually (A). Every 12 months or 6,000 miles (9,654 km), whichever comes first. (3) Biennially (B). Every 24 months or 12,000 miles (19,308 km), whichever comes first. (3) Clean fittings before lubrication. Clean parts with drycleaning solvent (SD), type II, or equivalent. Dry before lubricating. Relubricate all items found contaminated after fording. .WARNING. Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with effective chip guarding and personal protective equipment such as goggles or shield, gloves, etc. NOTE Use compressed air to dry electrical components. Use sealing compound (Appendix C, Item 40) before reconnecting plugs. (4) Inspect electrical connectors for corrosion and/or damage (i.e., bent pins). Clean and repair damage. Clean electrical components with clean cloth dampened with drycleaning solvent. Care must be taken not to damage protective insulation. (5) Read “Processing and Deprocessing Record of Shipping, Storage, and Issue of Vehicles and Spare Engines,” tag (DD Form 1397) and follow all precautions listed. This tag should be attached to steering wheel, steering column, or rotary switch.
