Section III. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), LUBRICATION
INSTRUCTIONS, AND MANDATORY REPLACEMENT PARTS
INTRODUCTION
a. General.
Preventive maintenance is the systematic care, inspection, and service of the M60A1 AVLB
launcher to keep it in serviceable condition and to detect faults and failures before extensive
and time consuming repairs or replacement are required. Maintenance checks are services
performed by organizational maintenance and are described below.
This section contains the procedures and instructions to perform M60A1 AVLB launcher
organizational preventive maintenance checks and services. These services are performed by
organizational maintenance personnel assisted by the vehicle crew. Ensure that all crew level
hull PMCS procedures have been completed prior to performing organizational PMCS. Refer to
DA PAM 738-750 for instructions on the use of forms pertaining to PMCS.
Organizational services are defined by, and restricted to, the procedures outlined in this section
and Appendix B, Maintenance Allocation Chart, unless approval to perform higher category
services has been given by the support maintenance unit.
Knowledge of operating and maintenance procedures outlined in TM 5-5420-202-10 is essential
to the performance of organizational PMCS. Organizational mechanics must be familiar with
these procedures so that they can apply them in the performance of their duties.
The driver of the vehicle is often unaware of gradually developing defects. Therefore, the
vehicle must be road tested by organizational maintenance personnel during preventive
maintenance checks and services. Any repairs or adjustments necessary to ensure safe
operation should be made prior to road test. All faults and corrective actions will be noted on
DA Form 2404. The item number recorded in column "a" of DA Form 2404 must correspond
to the PMCS item number. After deficiencies have been corrected and the tactical situation
permits, an additional road test must be made for a distance of not less than three nor more
than five miles.
The preventive maintenance checks and services listed in this section are to be performed on
condition and semiannually.
Hard (fixed) time intervals 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. Change the interval if your lubricants are contaminated or if you are
operating the equipment under adverse conditions, including longer-than-usual operating hours.
The interval may be extended during periods of low activity. If extended, adequate preservation
precautions must be taken.
PMCS items and intervals have been determined by using Reliability Centered Maintenance
(RCM) logic.
