T
ankers, if the breech on your tank seems to take forever to close, deformed breech-
block springs could be the culprit.
If they’re left com-
pressed for extended peri-
ods of time, the springs lose
their spring. They just don’t
have enough oomph left to
close the breech quickly.
So if you’re going to
park your tank for a while,
make sure the breech is
closed
when you leave.
That not only releases the
pressure on the springs, but
it helps keep dust and cor-
rosion-causing
moisture
out of the breech, too.
I
f your tank’s replenisher has been drained for maintenance, or if you’re preparing
for a firing exercise, you
must
remember to check the FRH level in the replenisher,
crewmen.
If the recoil system is low on fluid,
the main gun could recoil uncontrol-
lably the next time it’s fired. When that
happens, the cannon shears its retaining
bolts and slams into the ammo compart-
ment—bad news for anyone who hap-
pens to be in the way!
Just making sure the FRH reaches the
MIN LEVEL mark on the replenisher
isn’t good enough, either. If there’s air
in the system, the replenisher could give
you a false reading.
Go ahead and bleed the system, following the instructions on Page 2-344 of TM
9-2350-255-10-1, Page 2-369 of TM 9-2350-264-10-1, Page 2-729 of TM 9-2350-
288-10-1 and Page 2-686 of TM 9-2350-388-10-1. Bleeding the recoil system will
remove excess air and give you an accurate reading.
Make a note of this requirement until it can be added to the BEFORE operations
PMCS tables.
Air in recoil system can give
false reading on replenisher

what’s
with the
breech
today?
it closed
so
slowly
I coulda
used an
hourglass
to time it!
the breech-
block springs
must be
sprung!
awright you
guys, let’s go
for a
perfect
score
on the
range today!
there won’t be
anything
perfect
about this firing exercise if you don’t
check my
replenisher level!
Keep breech closed
