Turn the Defroster
Off
G
ot a problem with frost on the eyepiece of your gunner’s primary sight (GPS)?
Just flip on the GPS defroster. In a few minutes your problem clears up.
But if you forget to turn off the
defroster, you have a new problem.
The defroster doesn’t turn itself
off when the frost is gone. It keeps
right on running.
A long-running defroster will
overheat and crack the daylight
window on the GPS.
So when the frost is gone, turn
off the defroster.

M1-Series Tanks…
M
ost tankers feel that noth-
ing can stop their M1-series
tank.
..until you throw a litle ice and
snow into the equation. Without traction,
you’re going nowhere.
FM 9-207 says it’s OK to remove track
pads to improve traction. But that can damage track
components and still doesn’t provide much traction.
For tanks with T158/T158LL track, special ice
cleats, NSN 2530-01-369-9994, are available to prevent all that
slipping and sliding.
4.
Install two ice cleats on
the track shoe in place of the
removed pads.
5.
Lock each cleat in place with a new
self-locking nut, NSN 5310-01-102-
2711. Torque the nuts to 260-300 lb-ft.
6.
Follow steps 3-5 for the track on the
other side of the tank.
7.
Move the tank forward to position
the next track shoe needing cleats.
For best performance, put a set of cleats on every fifth shoe. That means you’ll
need a total of 60 cleats for each vehicle (30 per track).
Remember, these cleats are for T158/T158LL track only. They will not work with
T156 track.
