T
he newly installed gunner’s restraint system (GRS) on the M1126 ICV, M1127 RV,
M1130 CV, M1131 FSV, and M1132 ESV Strykers won’t do much restraining if it’s
not installed right.
The right-rear retractor for the
air sentry guard GRS was installed
the wrong way on some of these
Strykers. The bracket that mounts
the retractor to the ±oor was ±ipped,
moving the retractor closer to the
center of the vehicle.
Unfortunately,
that
places
the
retractor too close to the ramp. When
the ramp is closed, it hits the retractor
casing and cracks it. Then the GRS
webbing can bind as it retracts. That
can keep it from tightening properly,
which puts you at risk.
As part of your before-operations PMCS, inspect all of the GRS harnesses,
retractors and brackets, but pay special attention to the right-rear air guard bracket.
If the bracket is installed wrong, it’s considered a safety issue and your vehicle is
NMC until the problem can be ²xed. Notify your mechanic and he’ll correct the
bracket orientation.
If the bracket was installed properly and there’s enough clearance for safe
operation of the retractor, you’re good to go. However, there may be a few vehicles
that still have an interference problem even after the bracket is reinstalled correctly.
In those cases, tell your mechanic.
He’ll replace the old bracket with
a new one, CAGE 1EAW9, PN
DTA201374.
The
new
bracket
mounts the same way, but has been
reshaped to move the retractor
3
/
4
inch farther out of the way. The
bracket is also stamped with the
word
TOP
for proper orientation.
You’ll ²nd the complete scoop on
this issue in TACOM GPA 11-007.
D
rivers, when you exit your M88A1-series recovery vehicle, do you sometimes feel
a little tug on your pants?
That’s because it’s easy to snag the back of your coveralls on the engine ²re
suppression system safety pin. If the pin is pulled out—even slightly—it activates a
sensor that keeps the engine from starting the next time.
So if you feel a little
tug on the back of your
coveralls
at
the
end
of the mission, reach
back and make sure the
safety pin is pushed in
all the way.
If the engine won’t
start next time, you may
not have noticed the
snag. Make the safety
pin your ²rst check.
