TM 9-2350-261-20-1 PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDING LUBRICATION INSTRUCTIONS — Continued 0120 00 h. Stop engine (see your -10). i. Uncover air inlet grill. EXPLANATION OF PMCS TABLE ENTRIES (1) 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 appear in the order that you must do the checks and services for the intervals listed. (2) Interval Column — This column tells you how often you must perform the checks/services. Semi-annual checks/services must be performed every six months or after 1500 miles (2400 km) of operation. (3) Man-Hour Column — This column gives the man-hours (to the nearest tenth of an hour) needed to complete the prescribed lubrication service. This column is used only for lubrication services. (4) Item To Be Checked or Serviced Column — This column lists the item to be checked or serviced. (5) Crewmember/Procedure Column — This column gives the procedure you must do to check or service the item listed in the Item To Be Checked or Serviced column to know if the equipment is ready or available for its intended mission or for operation. You must do the procedure at the time stated in the interval column. (6) Equipment Not Ready/Available If: Column — Information in this column tells you what faults will keep your equipment from being capable of performing its primary mission. If you perform check and service procedures that show faults as listed in this column, do not operate the equipment. Follow standard operating procedures for maintaining the equipment or reporting equipment failure. LUBRICATION TABLES The following tables are used during PMCS lubrication checks. Intervals (on-condition or hard time) and the related man-hour times are based on normal operation. The man-hour time specified is the time you need to do all the services prescribed for a particular interval. Hard time intervals will be indicated by one of the following symbols as appropriate: Semi-annually (S) and Annually (A). On-condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program (AOAP) Laboratory. Change the hard time interval if lubricants are contaminated or if you are operating equipment under adverse operating conditions, including longer-than-usual operating hours. The hard time intervals may be extended during periods of low activity if adequate preservation precautions are taken. Hard time intervals will be applied to oil changes in the event AOAP Laboratory support is not available. On-condition (OC) AOAP Laboratory determined oil change intervals shall be applied instead of hard time intervals such as hourly, calendar, or mileage, unless otherwise notified. The services will be required when directed by an Army Analysis Program (AOAP) Laboratory which has analyzed the oil for serviceability. Clean fittings before lubricating. Clean parts with cleaning compound (WP 0782 00, Item 16). Unless specifically identified, all procedures apply to M113A2, M577A2, M901A1, M981A1, M1059, M1064, and M1068 carriers. NOTE Park carrier on level ground to check oil levels. Check/lubricate all oil and grease fitting points after washing or fording. ARMY OIL ANALYSIS PROGRAM (AOAP) — AOAP is an effective maintenance diagnostic tool and not a maintenance substitute. TB 43-0211 must not be interpreted to mean AOAP minimizes, in any way, the need to employ good maintenance practices and strong maintenance disciplines. SAMPLING REQUIREMENTS — Samples may be taken without WARMING a component to operating temperature if the equipment has been operated within the last 30 days. If the equipment has not been operated within the last 30 days, the components must be brought to operating temperature. These requisites apply to both routine and special sampling. Oil samples must not be taken immediately after oil is added. When oil sampling valve is not available to take oil sample, use a vampire pump. 0120 00-13
