A
loud SQUE-E-E-E-AL and the smell of burning metal aren’t supposed to be part
of recovery operations, drivers. ‘Course, not lubing your Stryker’s winch pulleys
aren’t exactly SOP, either.
Forget
the
lube
and
the
pulleys can lock up. Then the
winch cable is damaged by
friction as it passes over the
pulleys.
Keep those pulleys turning
nice and smooth. A few pumps
of GAA once a month will do
the trick. Lubrication of the
pulleys is covered under Item
5 of the monthly PMCS tables
for all Fttings and cable.
And when you’re Fnished
with recovery operations, leave
a small amount of slack in the
winch cable. That keeps the
cable from rubbing against the
corner of the front hatch when
it’s opened.
M
echanics, if your face is red and there’s a big vein pulsing in your forehead, you’re
probably being a little heavy-handed with the desiccant assembly on the doghouse
body of the gunner’s primary sight (GPS).
When the desiccant is replaced, some of you are being especially rough on the
cover screws, NSN 1240-01-267-8162.
If you screw in the covers too tight, the screw slots get chewed up. Your job just
got a lot harder the next time the screw covers have to be removed.
Inside both of the screws is an O-ring, NSN 5331-01-079-2931. It’s the O-ring’s
job to keep the chamber pressurized, not yours.
So tighten the screw cover down, but not so much that you damage the slot. And
it’s a whole lot better for your blood pressure, too!
