elieve it, crewmen. Just a few missing cable ties can leave your driver’s vision
enhancer (DVE) totally in the dark.
Those cable ties are used to hold the DVE cable inside a channel guide that runs
from the DVE camera to the screen. The channel guide runs between the engine
access and driver’s hatches and then below the driver’s hatch.
Broken or missing ties let the cable escape from the channel guide. It won’t be
long before the cable gets caught in one or both of the two hatches.
CRUNCH!!
Your unit’s pocketbook also feels
the
crunch. A
replacement
DVE
cable, NSN 6150-01-566-9322, will
cost more than $700.
Crewmen, take a quick look at
the cable ties as part of your before-
operation
PMCS.
There
should
be a total of 12 ties, each spaced
approximately
four
inches
apart.
Replace any that are broken or missing
with NSN 5975-00-899-4606. That
NSN brings 100 new cable ties.
Mechanics, if you have to replace a damaged DVE cable, don’t forget to secure the
new one with cable ties. Otherwise, you’ll soon be replacing the cable again.

hat happens if you Fre a gun with someone’s Fnger stuck in the barrel? Well, it
doesn’t do the gun much good and you sure don’t want it to be your Fnger!
‘Course Fngers are a bit too small to plug the gun tube on an M1-series tank. But
lots of other things can. If anything’s plugging the gun tube when it’s Fred, the tube
could bulge or even blow up!
That’s why you should always be careful during operations. It only takes a
few seconds for a scoop of sand or dirt to plug the gun tube, so follow these
precautions:
•
Always use the muzzle cap when the main gun isn’t being used.
•
When necessary—like during emplacement—keep the main gun elevated to keep
it from hitting the ground.
•
If you have any doubts at all, check the gun tube for obstructions before Fring.
If you Fnd an obstruction, clean the gun tube. The procedures start on Page 3-250
of TM 9-2350-264-10-2 (Mar 03 w/Ch 6, Jun 09) and WP 0514 of TM 9-2350-388-
10-3 (±eb 09).
