a. While performing specific PMCS procedures, make sure items are correctly assembled, secure,
serviceable, not worn, not leaking, and adequately lubricated as defined below:
(1) An item is CORRECTLY ASSEMBLED when it is in proper position and all parts are present.
(2) When wires, nuts, washers, hoses, or attaching hardware cannot be moved by hand, wrench, or
prybar, they are secure.
(3) An item is UNSERVICEABLE if it is worn beyond established wear limits, or is likely to fail
before the next scheduled inspection.
(4) An item is WORN if there is play between joining parts, or warning and caution plates are not
readable.
(5) LEAKS. TM 9-2320-260-10 contains definitions of class I, II, and III leaks and their effect on
vehicle operation.
(6) If an item meets the requirements specified by lubrication order, LO 9-2320-260-12, then it is
ADEQUATELY LUBRICATED.
b. Where the instruction "tighten" appears in a procedure, you must tighten with a wrench to the given
torque value even when the item appears to be secure.
WARNING
Drycleaning solvent is flammable and will not be used near open
flame. Use only in well-ventilated places. Failure to do so may
result in injury to personnel.
c. Where the instruction "clean" appears in a procedure, you must use drycleaning solvent, specification
P-D 680, to clean grease or oil from metal parts. After the item is cleaned, rinsed, and dried, apply a light
grade of oil to unprotected surfaces to prevent rusting. To clean rubber and plastic materials, use soap
and water.
a. The preventive maintenance checks and services for which you are responsible are provided in
table 2-1. The checks and services listed are arranged in logical order requiring minimal time and effort
on your part.

(1) Item Number. Provides logical order for PMCS performance and is used as a source number for
DA Form 2404, on which your PMCS results will be recorded.

same interval. Interval columns include:
(a) Semi-annual. Every 6 months or 6,000 miles (9,654 kilometers), whichever comes first.

(3) Item To Check/Service. Lists the system, common name, or location of the item to be inspected.

as needed.
