PREVENTIVE MAINTENANCE CHECKS AND SERVICES Continued
EXPLANATION OF TABLE ENTRIES
Item Number Column Numbers in this column are for reference. When completing DA Form 2404 (Equipment
Inspection and Maintenance Worksheet), include the item number for the check/service indicating a fault. Item numbers also
appear in the order that you must do checks and services for the intervals listed.
Interval Column This column tells you when you must do the procedure in the procedure column.
BEFORE procedures must be performed prior to the equipment leaving its containment area or performing its mission.
DURING checks are performed by the track commander/gunner per the PMCS table to monitor and identify faults in
equipment performance during the mission.
AFTER procedures are performed per the PMCS table at the conclusion of the mission to identify and correct faults
which will preclude the next mission.
WEEKLY as well as BEFORE PMCS procedures must be performed if:
You are the assigned crewmember and have not operated the hull since the last WEEKLY.
You are operating the carrier for the first time.
When a check or service procedure is required for both WEEKLY and BEFORE intervals, it is not necessary to do
the procedures twice.
Man-hour Column Man-hours required to complete all prescribed lubrication are shown to the nearest tenth of an hour.
Item To Be Checked or Serviced Column This column lists the item to be checked or serviced.
Crewmember/Procedure Column This column gives the procedure you must do to check or service the item listed in the
Item To Be Checked or Serviced column to know if the equipment is ready or available for its intended mission or for
operation. You must do the procedure at the time stated in the interval column. Carefully follow these instructions. If you do
not have the tools, or if the procedure tells you to, have unit maintenance do the work.
Equipment Not Ready/Available If: Column Information in this column tells you what faults will keep your equipment
from being capable of performing its primary mission. If you make check and service procedures that show faults listed in
this column, do not operate the equipment. Follow standard operating procedures for maintaining the equipment or reporting
If you find something wrong when performing PMCS, fix it if you can by using Troubleshooting Procedures (WP 0054 00) or
maintenance procedures. Notify unit maintenance if you cant fix it.
Take along the tools you need to make all the checks. You ALWAYS need a wiping rag (WP 0083 00, Item 16) or two and an
adjustable wrench (WP 0081 00, Item 43) to tighten loose fittings.
When you inspect for GOOD CONDITION, you look at the item to see that it is safe and serviceable.
When you inspect for CORRECT ASSEMBLY AND STOWAGE, you look at the item to see if it is present and installed
correctly and securely.
There are some items that need to be checked that are common to all parts of the carrier. keep your wrench and rag handy and
check these items each time you do your BEFORE preventive maintenance.
KEEP IT CLEAN
Dirt, grease, oil, and debris only get in the way and may cover up a serious problem. While doing your PMCS, clean as you
work and as needed. Use cleaning compound on all metal surfaces. Use soap and water when you clean rubber or plastic
BOLTS, NUTS, AND SCREWS
Check them all for obvious looseness, missing, bent, or broken condition. You cant try them all with a tool, but you can look
for chipped paint, bare metal, or rust around bolt heads. If you find one you think is loose, tighten it. If you cannot tighten it,
report it to unit maintenance.
