ere’s some good news for mechanics who are tired of repairing broken or
bent telephone cable reel brackets welded to the backs of M992-series ammo
carriers. A new, screw-on bracket is now available that’s easier to remove and
repair.
First, you’ll need to get rid of the old bracket:
1.
Remove the reel and set it aside.
2.
Use a sledgehammer to break the two bracket arms loose from where they are
welded to the hull. Grind the surface smooth with the drill grinder attachment,
NSN 3460-00-529-2105, from the No. 1 Common shop set.
3.
Touch up the metal with
CARC paint.
Now install the new
bracket:
1.
Mark four hole locations
on top of the NATO slave
receptacle guard like so:
M992-Series Ammo Carriers . . .
M992A2 Ammo Carrier . . .
Universal Joint Changes
M
echanics, before you check, repair or tighten the universal joint assembly on
an M992A2 ammo carrier, note these changes to TM 9-2350-293-20-1:
•
Item 13 on Page 2-27 of the PMCS tables says to torque the mounting bolts
to 90 lb-ft, but that’s too tight. The correct torque is 37–42 lb-ft.
•
Para 9-3, Universal Joint Repair, provides
no
torque specifications for the
mounting bolts. Again, the correct torque is 37–42 lb-ft.
•
Para 3-2, Powerpack Replacement, refers you to TM 9-2350-293-10 for
disconnecting the universal joints. That’s wrong. It should refer you to Para
9-3 of TM 9-2350-293-20-1.
Make a note of these changes until the TM can be updated.
4.
Secure the reel on the new bracket with two retaining clamps, NSN 5340-00-
933-7464; four screws, NSN 5305-00-068-7837; and four lock washers, NSN
5.
Slide the hand crank back through the reel and secure it with a new cotter
Lay the new bracket, NSN 2590-00-933-9011, on top of the guard to make sure
the holes will line up.
2.
Drill four

-in diameter holes using drill bit, NSN 5133-00-227-9670, from
the No. 1 Common shop set.
3.
Install the new bracket using four screws, NSN 5305-00-068-0511; eight flat
washers, NSN 5310-00-080-6004; four lock washers, NSN 5310-00-637-9541;
and four nuts, NSN 5310-00-732-0558.
