PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDING
LUBRICATION INSTRUCTIONS Continued
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: Daily (D), Weekly (W), Monthly (M), 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 0928 00, Item 19).
Unless specifically identified, all procedures apply to M58, M113A3, M577A3, M901A3, M981A3, M1059A3, M1064A3,
and M1068A3 carriers.
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 43-0210 or TM 9-2300-422-23&P 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
OIL CAN POINTS Every 1500 miles, semi-annually or as required, lubricate fan tensioner, ramp hinges, ramp door
hinges, power plant door hinges, drivers, commanders and cargo hatch hinges, control linkage pins and shafts and seat
control. Use OE/HDO or OEA as appropriate.
