rewmen, it’s out-of-sight, out-of-mind when it comes to lubing the idler wheel
support arms on your M113-series carrier.
Support
arms
sit
behind
the idler wheels and are often
covered
with
mud,
so
the
grease Fttings are easy to miss.
If
you
forget
too
often,
though, the bearings dry out
and
the
idler
arm
freezes.
When the arm won’t move, you
can’t adjust track tension.
Your
vehicle is NMC.
Lube both idler arms with GAA every 150 hours of operation, 1,500 miles or
semiannually, whichever comes Frst.
Clean the Fttings with dry cleaning solvent
Frst to keep dirt from mixing with the grease.
Put a dab of lube on the grease Fttings immediately after washing or fording the
vehicle, too.
That’ll keep the valves from rusting.
T
he Army is running out of Bradley A3-series improved Bradley acquisition system
(IBAS) repair parts because units aren’t turning in unserviceable IBAS components.
The depot doesn’t have IBAS components to repair and the supply pipeline goes
dry. The Army is forced to purchase new replacement parts, which costs a whole bunch
of money.
So if you have any IBAS items (weapon system code EH) that are considered
unserviceable/repairable (condition code F), turn them in NOW!
These items are in especially short supply:
NSN
P/N
Periscope head assembly
Monocular assembly
Xenon tracker assembly
Missile control subsystem
Laser shutter assembly
Collimator, infrared
Circuit card assembly, IBAS frame buffer
Lower target acquisition subsystem

Circuit card assembly, quad C40

Circuit card assembly, range logic card
