PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
INTRODUCTION
INTRODUCTION
Preventive Maintenance Checks and Services (PMCS) provide scheduled procedures to maintain the
TWPS at a specified level of performance by providing systematic inspection, detection, servicing,
condition monitoring, and/or replacement to prevent impending failures. The following PMCS schedules
are established for:
1. Maintenance to perform PMCS called out in Table 1, BEFORE start-up and operation of the
TWPS. Service Upon Receipt from storage is covered separately in WP 0036.
2. Maintenance to perform PMCS called out in Table 1, DURING operation of the TWPS.
3. Maintenance to perform PMCS called out in Table 1, AFTER operation, shut down and cool-down
4. Maintenance to perform PMCS at the interval hours of operation called out in Table 2.
PMCS TABLE FORMAT
Preventive Maintenance Checks and Services (PMCS) tables list inspection and care requirements to
keep the TWPS in good operating condition. The tables are set up to allow the operating crew to make
checks during a walk-around of the unit. The following describes the purpose of each column in each
PMCS Table.
1. ITEM NO: Each maintenance check is identified by a separate item number. The item column
will be used as a source of item numbers for the "TM Number" on DA Form 2404, Equipment
Inspection and Maintenance Worksheet, in recording results of PMCS.
2. INTERVAL: This column indicates when to perform the service check or maintenance.
Before
During
After
Periodic (see procedure for weekly, hours, quarterly, etc.)
3. ITEM TO BE CHECKED OR SERVICED: this column identifies the component, assembly, or
system to be checked or serviced.
4. PROCEDURE: This column identifies what check or inspection task to perform and what action
to take if corrections need to be made. Appropriate work packages are also referenced here.
5. EQUIPMENT NOT READY IF: This column indicates equipment conditions that make the
equipment not capable of performing its assigned mission.
GENERAL INSPECTION AND MAINTENANCE
The following general inspection and maintenance procedures can be performed at any time. It is a good
practice to perform these general procedures regularly to ensure that the TWPS remains in good
operating condition.
1. Keep the TWPS clean. Dirt, grease, oil, and debris get in the way and may cover up serious
problems.
