Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
5-4. PMCS INTRODUCTORY MATERIAL.
This section contains Preventive Maintenance Checks and Services PMCS instructions for the vehicle. The PMCS Table
contains checks and services necessary to ensure that the vehicle is ready for operation. Unit PMCS procedures are
defined by the MAC. Unit PMCS is performed at the intervals specified in Table 5-2. Preventive Maintenance Checks and
Services in Chapter 4 should be completed before performing DS/GS PMCS.
5-5. MAINTENANCE FORMS AND RECORDS.
Maintenance forms and records provide permanent records of maintenance services, repairs, and modifications made on
the vehicle. They provide reports to organizational maintenance and the commander, and they serve as a checklist to find
out what was wrong with the vehicle after its last use and whether those faults have been fixed. For information needed on
forms and records, see DA Pam 738-750.
5-6. GENERAL PMCS PROCEDURES AND CONDITIONS.
The following paragraph describes general procedures and conditions that should be observed when performing PMCS.
a.
General Guidelines.
(1)
Limit repairs to those actions necessary to ensure mission reliability, safety of personnel, and prevention of
further damage or deterioration. Repairs, replacements, or services for cosmetic purposes are forbidden.
(2)
Lube oil sampling. Engine oil must be sampled at 50 hours of operation or 90 days, whichever occurs first, for
Active Army Units. Reserve and National Guard Activities will use 50 hours or 180 days, whichever occurs first, as the
prescribed interval. Hydraulic fluid will be sampled once-a-year. Sampling will be performed as prescribed by DA Pam 738-
750.
(3)
Lube oil filters. Oil filters shall be serviced/cleaned/changed as applicable when they are known to be
contaminated or clogged; service is recommended by AOAP laboratory analysis; or at prescribed hard time intervals.
(4)
Hydraulic systems (other than brake systems) may have Class III leakage and not be cause for deadlining.
Components, such as actuating cylinders, are designed to allow a certain amount of fluid to pass by the ram seal to lubricate
the seal and ram. This could be interpreted as a Class III leak. The decision as to whether or not the vehicle should be
deadlined is based upon good mechanical knowledge and common sense.
(5)
Corrosion prevention and control (CPC). It is important that any corrosion problem with this vehicle be
reported so that the problem can be corrected and improvements can be made to prevent the problem in other vehicles.
Corrosion should be reported using Standard Form 368, Product Quality Deficiency Report (QDR). Use keywords such as
corrosion, rust, deterioration, or cracking to ensure that the information is identified as a CPC problem. Send Std Form
368 to Commander, U.S. Army TACOM, Attn: AMSTA-QRD, Warren, MI 48397-5000.
