echanics, if any of the Bradleys
in your unit have uparmor driver’s
hatches, NSN 2510-01-391-1045,
check ’em out now to save valuable
time and money.
Moisture from rain and condensa-
tion is getting trapped inside the tor-
sion bar support tube and rusting the
torsion spring. A rusted spring makes
the hatch hard to open or close from
inside the driver’s station. Eventually,
the hatch won’t move at all.
A coating of sealant on the back of
the support tube cover, NSN 2590-
01-392-5150, is holding in the mois-
ture. So, remove the cover, scrape off
as much sealant as possible, then
clean the rest off with dry cleaning
solvent.
M1A1 Wiring Harness
F
ig 140 of TM 9-2350-264-24P-2 says Item 10 is a 1W108-9 wiring harness.
Actually, Item 10 is the 1W108-2 wiring harness, NSN 6150-01-392-0063. The
1W108-9 harness, NSN 5995-01-189-7722, is only needed for M1A1 tanks
without MWO 9-2350-264-50-2-5 applied.

M2/M3-Series Bradley . . .
Do not
reseal the cover before re-
installing it! That just starts the prob-
lem all over again.
With the sealant gone, moisture can
drain from the support tube. No mois-
ture, no rust.
See TACOM maintenance advisory
message (MAM) 98-017 for more
details.
Remove cover and clear away sealant
revent Bradley ammo chute damage with one simple rule: Hook up the
ammo chutes when you install the M242 automatic gun.
Bradley crews sometimes forget to hook up the chutes, especially if they’re
not going to fire. Then when the gun is raised or lowered, the chutes catch on
cables and the chute locking levers
are damaged. The chutes can also rip
out cables and wiring, causing the tur-
ret to lock up.
Don’t pitch damaged ammo chutes.
They can be fixed with the fitting re-
pair kit, NSN 2320-01-268-7915.
