A
t the end of a long day, after-operation PMCS might be the last thing on your mind.
But your job’s not done until that job is done!
Servicing
the
main
gun tube,
bore
evacuator and breech is especially important.
You need to inspect, clean and service each
item just like it’s spelled out in the TM.
These checks are for your own safety
because overlooking even small details can
lead to serious consequences. For example,
something as simple as a torn bore evacuator
O-ring can result in a deadly ±areback!
Clean the main gun tube. Remove the bore
evacuator and inspect the seals. Disassemble
the breech and inspect its parts.
The proper procedures can be found in
WPs 0455, 0456, and 0458 of TM 9-2350-
264-10-3 (Dec 12) and WPs 0547, 0548,
0550 of TM 9-2350-388-10-3 (Dec 12).
W
hen the M1A1 tank’s M1A1-19
precleaner stops working due to lack
of air ±ow, some units replace the
entire precleaner.
This isn’t necessary
unless the precleaner is damaged.
Most of the time the problem is
that the M19 particulate ²lter, NSN
4240-00-866-1825, is dirty.
In that
case, just replace the M19 ²lter.
The procedures for maintaining
and replacing the M19 ²lter are in
TM 3-4240-276-30&P (Dec 97).
Disassemble breech and inspect for damage
Usually
