here's nothing better than powerful PM for the Patriot system. For instance:
Antenna Mast Group
When operating the
two pneumatic pumps
on the AMG, take the
pumps' cover complete-
ly off. Otherwise, heat
becomes so intense that
it melts the plastic guard
over the fan. Then the
motor overheats.
EPP3
Remember the oil levels will be dif-
ferent depending on whether the EPP3
is shut down or running. If you check
the oil while the generator is running,
the level will be lower. Then you mis-
takenly overfill with oil and pop the
seals. See the sticker above the EPP3
dipstick for the proper way to check the
oil. The generator normally uses oil, so
check the oil level daily in the field.
Patriot Missile System…
M983 Truck
Watch your feet around the
M983's sensor for the power take-
off (PTO). It is often snapped off
by a misplaced boot, especially
when crews are putting up camou-
flage or doing PMCS. No sensor
deadlines the truck.
You can now order a PTO guard
Don't check the M983's transmission fluid without letting the engine warm up to
operating temperature. Crews are checking the fluid with the engine cold and that
gives a low reading. Too much fluid is added to the transmission and that blows
transmission seals. The engine temp should 160°F for the check. Add just enough
fluid to reach the HOT RUN on the dipstick.
During weekly PMCS, check for
the dust caps for the four rear brake
chambers. The old-style caps often
disappear and without them dirt gets
in the brakes and weakens their
stopping power. It's a good idea for
your repairman to keep extra caps on
hand. He can order them with NSN
are held in place with a screw.
