Section III. PREVENTIVE
4-8. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
Table 4-1 Iists preventive maintenance checks and services (PMCS) which shall be performed at specified
intervals by organizational maintenance personnel. It expands upon the preventive maintenance services
performed by operator maintenance and includes additional services which are allocated to organiza-
tional 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 (A) DA Form 2404, Equipment Inspection and Main-
tenance Worksheet, in recording results of PMCS. USMC personnel maintain forms and records
described by TM 4700-15/1.
b. The service intervals are divided into four categories:
W - Weekly; M - Monthly; Q - Quarterly;
S - 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.
c. 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 equipment requiring the check or service.
e. The designations left, right, front, and rear as used in PMCS indicate the side or end of the
centrifugal pump as viewed when facing the throttle control.
