GENERAL.
Preventive Maintenance Checks and Services (PMCS)
means systematic caring, inspecting, and servicing of
equipment. This will keep it in good condition and
prevent breakdowns. As a paving machine mechanic,
your mission is to:
a. Be sure to perform your PMCS at the
scheduled time. Always do your PMCS in the same
order, so it becomes a habit. With some practice,
anything wrong is quickly spotted.
b. Do your PMCS at its scheduled interval.
c. Check to see if items are in good condition,
properly assembled or stowed, properly lubricated, and
not loose or excessively worn.
(1) Checking that items are in good condition is
usually a visual check to see if the items are safe and
usable. Good condition means not bent or twisted,
chafed or burred, broken or cracked, bare or frayed,
dented or collapsed, torn or cut, rusted or rotted, and not
leaking.
(2) Checking that items are properly assembled
or stowed usually is a visual inspection. See if the items
are in normal positions on the vehicle, and if all parts are
present.
(3) Excessively worn means worn beyond usable
limits and likely to fail before the next scheduled
inspection. This includes too much play (lash or lost
motion) in linkages and mating parts. This includes
unreadable markings, data and caution plates, and other
printed matter.
(4) Check welds for loose or chipped paint, rust,
or gaps where parts mate together.
d. The specific PMCS procedures do not say
"adjust if necessary" or "replace if necessary". It is
understood that whenever inspection shows the need for
adjustments, repairs, or replacements, that appropriate
work will be done.
e.
Steel
nameplates,
caution
plates,
and
instruction plates may rust rapidly. Clean rusty plates well
and coat heavily with clear lacquer. Refer to TM 43-0139.
f. General precautions for cleaning are in the
maintenance sections.
g. The vehicle operator normally helps the
organizational
maintenance
personnel
perform
the
PMCS. The operator should make sure the paving
machine is fairly clean. Do not wash the paving machine
immediately before doing PMCS.
h. The only organizational maintenance services
are those general procedures listed below, unless
approval is given for other service.
(1) Adjust. Make all adjustments by following the
procedures given in this manual or in bulletins.
(2) Clean. Clean items by following the general
cleaning procedures given in paragraph 2.6.
(3) Service. Normally, service includes draining
and refilling items with oil, and changing or cleaning the
oil filter, air cleaner, or cartridges.
(4) Tighten. Tighten items with enough force on
the wrench handle to tighten according to good
mechanical practice. Do not over-tighten; this may strip
threads or cause distortion. Tightening includes using
lockwashers, lock nuts, lock wire, or cotter pins when
needed. Use a torque wrench when the procedure calls
for one.
(5) Modification work order application. Write all
needed modification work orders (MWO) for the vehicle
on DA Form 2408-5.
i. When it is hard to do all of the PMCS
procedures at one time, they can sometimes be done in
parts. If possible, plan to do all the procedures within one
week.
j. Use DA Form 2404 (Equipment Inspection and
Maintenance Worksheet) to record any faults that you
discover, unless you can fix them. You DO NOT need to
record faults that you fix.
