S
ome units have been removing the ammunition handling system replenisher from their
M1128 MGS Strykers. Why? To make room for more passengers and more coax and .50 cal
machine gun ammo.
That’s a
very bad
idea.
When
the
replenisher
is
removed,
sensitive
components are left exposed.
The NBC system, fuel system
crossover valve, fuel transfer
valve,
and
numerous
hydraulic
tubes
normally
protected by the replenisher
are easily damaged.
Item 52 of the Before PMCS chart in WP 0543-27 of TM 9-2355-321-10-1-4 says it all: The
vehicle is
not mission capable
if the replenisher is not functioning properly. Obviously, it
can’t function properly if it isn’t in the vehicle.
The only time the replenisher should be removed is during maintenance. And even
then, precautions must be taken. The next update to TM 9-2355-321-10-1-1 will include the
following warning in WP 0056 and WP 0069:
T
he right tool for the right job. That’s the only way to make sure the job gets done right.
Unfortunately, some of you crewmen are trying to use the wrong tool when extracting
a stub base or stuck round from your tank’s 120mm cannon tube. That can increase the
danger of flareback.
If a stub base doesn’t extract from
the chamber after Fring, don’t just
grab whatever you can Fnd to get it
out. Use the cartridge ejector tool, NSN
1015-01-209-3484. It’s listed as Item 20
in App B of TM 9-2350-264-10-2 and
Item 22 in WP 0555-7 of TM 9-2350-
388-10-3.
A stuck round should be removed
with the M5 cleaning and loading
rammer (bell housing), NSN 1015-01-
170-4911, and rammer staff, NSN 1015-
00-699-0633. These tools are listed as
Items 61 and 75 in App B of the -264-
10-2 TM and Items 62 and 80 in WP
0555 of the -388-10-3 TM.
Now that you’ve got the right tools,
make sure you use them the right way.
It is very important that all CAUTIONS
and WARNINGS be strictly followed
during these procedures.
±or M1A1 tanks, the procedures for removing a stuck stub base start on Page 2-505 of
TM 9-2350-264-10-1. The instructions for removing a stuck round start on Page 2-503.
±or M1A2 SEP tanks, the procedures for removing a stuck stub base are in WP 0299 in
TM 9-2350-388-10-2. Removing a stuck round is covered in WP 0298.

The complete scoop is in TACOM Maintenance Action message 09-035:
WARNING
While the replenisher is removed, personnel are not permitted in the rear of the vehicle
during normal operations. Turret movement and the lack of passenger restraints create
a potentially dangerous situation which may result in injury or death to personnel.
M1128 MGS Stryker…
Leave Replenisher Alone!
M1-Series Tanks…
Don’t
Get
Stuck With
Wrong
Tool!
Don’t
remove
replenisher
to make
more room
now that your replenisher
is out of the way, we’ve got
more room for passengers!
no way!
that’s a good
way to get
someone hurt!
Use right tools for job
Cartridge ejector tool,
Rammer staff,
Bell housing,
I Bet
this
will
remove that
stuck round!
yikes!
