TB 9-2320-335-13&P 2-2 a. While performing specific PMCS procedures, ensure items are correctly assembled, secure, not worn, serviceable, 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, they are SECURE. (3) An item is WORN if there is too much play between joining parts or when marking data, warning, and caution plates are not readable. (4) An item is UNSERVICEABLE if it is worn beyond repair and is likely to fail before the next scheduled inspection. (5) LEAKS. TM 9-2320-387-10 contains definitions of class I, II, and III leaks and their effect on vehicle operation. (6) If an item meets the specified lubrication requirements, 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 an open flame. A fire extinguisher will be kept nearby when the solvent is used. Use only in well-ventilated places. Failure to do this may result in injury to personnel and/or damage to equipment. c. Where the instruction clean appears in a procedure, you must use drycleaning solvent (appendix C, item 26) 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. d. Clean rubber and plastic materials with soap and water.
