Say

T
he M981 FISTV’s W29 collimator cable will not bend over backwards for you.
In fact, the crimped end of the con-
nector cuts into the insulation every
time the cable bends. Eventually, the
wiring is damaged and you can’t
boresight the FISTV’s night sight.
A little adjustment will prevent
that damage. Just loosen the loop
clamp, NSN 5340-00-543-3931, that
attaches the connector cap to the
W29 cable. Then, slide it up until the
clamp covers the weak spot.
Retighten the loop clamp and
you’ve got a ready-made support that
keeps the cable from bending.
If the cable shows chafing, wrap it
with electrical tape before moving
the loop clamp.
Y
ou’ll have a hard time towing your howitzer or ammo carrier if the towing lugs,
NSN 2540-00-031-7707, are broken. But broken lugs are almost unavoidable if
your vehicle has the wrong lugs attached.
The wrong lugs are made of
cast
aluminum and will break under the stress of
towing. They were accidentally mixed in with the
machined
aluminum lugs already
in the supply system.
Right now, check the towing lugs on your vehicle. Cast aluminum lugs will be
imprinted with letters and numbers.
If you find any cast aluminum lugs, tell your support. They can replace them.
if the cable’s
internal wiring
is damaged,
replace the
cable.
