M2/M3-Series Bradley…
Dear Editor,
To add damper fluid to the Bradley's
M242 gun's recoil system, TM 9-1005-
200-23&P says to push on the spring-
loaded damper rod with a brazing or welding
rod. That's difficult because the rod doesn't
have a handle to hold onto. We've found it's
easier to use the copper screwdriver that's
part of the Bradley's tool kit. Its handle
makes pushing on the damper rod easier.
To add damper fluid, it's also easier to use
a squirt bottle rather than try to pour the
fluid out of a can. We use the squirt bottle
that's part of the M1 tank's
bII
. You can
order one with NSN 8125-01-134-5409
for a little over $2.

M88A1 Recovery Vehicle…
Checking Valves Brings
Relief
W
hen was the last time you checked the roadwheel hub relief valves on your
M88A1 recovery vehicle, mechanics? Take a look now, especially if you’ve done
any recovery work recently.
Vibration can loosen the valves until
they fall out. Bushes can snag the relief
valve plunger and rip it loose. Either way,
water gets inside the road arm spindle
where it dilutes the grease and burns up the
spindle bearings.
Replace a missing relief valve with NSN
4820-01-070-7670. If the relief valve won’t
screw in easily, the threads inside the pipe
bushing may be damaged. Replace the pipe
bushing with NSN 4730-00-187-1413.
If the grease is contaminated, inspect and clean the hub following the instructions
starting on Page 8-9 of TM 9-2350-256-20 (Jul 96).
Check for missing or
damaged relief valve
What
is that
squeaking
noise!?
Editor's note:
No one will recoil from your recoil
suggestions. Thanks for sharing. You can now order
a damper valve tool with NSN 5120-01-452-3364.
…for
making it
easier
to
maintain
the m242.
here are a
couple of tips
from the new
york national
guard…
