eep a close eye on the hose saddle,
NSN 4730-01-173-9141, and mounting
bracket, NSN 5340-01-166-6379, that
clamp the transmission oil cooler hose
in place on your MLRS, crewmen.
After extended use and a lot of vibra-
tion, the two pieces can develop cracks.
The hose rubs against the cracked
pieces until a leak develops. If the leak
gets bad enough, the transmission is
damaged.
When the cab’s raised during PMCS,
eyeball the hose saddle and mounting
bracket carefully for cracks or breaks.
Then, get your mechanic to replace
either part as necessary. He’ll also need
to replace the hose, NSN 4720-01-408-
5669, if it shows excessive wear.

AVLB…
P
ulling and installing the powerpack
on your armored vehicle launched
bridge (AVLB) should be rated CG—
Crewman Guidance suggested.
That’s because the powerpack is
big, bulky, and hard to control.
Mechanics need all the help they can
get to keep the pack from hitting
things it’s not supposed to—like the
5-gal water can bracket, for instance.
The bracket gets crushed, of course. But it’s the unseen damage that’s the real
cause for concern. The edge of the water can bracket can cut or chafe some of the
fuel lines on the powerpack.
Cut or weakened fuel lines can leak and cause a fire. So, crewmen, lend your
mechanics a hand when it’s time to pull or install the powerpack in your AVLB.
Extra hands and eyes will prevent any damage.
