4-8. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
Table 4-1 lists preventive maintenance checks and services(PMCS) which shall be performed at specified intervals by
unit maintenance personnel. It expands upon the preventive maintenance services performed by operator maintenance
and includes additional services which are allocated to unit maintenance. The columns, codes, and location designations
used in the table are as follows:
a. Item numbers are assigned to each check or service task. The numbers are to be used as a source of item
numbers for the TM Number column on DA form 2404, Equipment Inspection and Maintenance Worksheet, in recording
results of PMCS.
b. The service intervals are divided into four categories: W-Weekly; M-Monthly; O-Quarterly; Semiannually. A dot
(-) is placed in the interval column for each check or service. If the same check or service is made in two or more
intervals, a dot is placed in each applicable column.
The Item to be Inspected column lists the item to be checked or serviced.
d. The Procedures column describes the procedure by which the check or service is to be performed. Illustrations
are included to assist in locating that part of the unit requiring the check or service.
e. The designations left, right, front, and rear as used in the PMCS indicate the side or end of the centrifugal pump
unit as viewed when facing the throttle control.
