hen you check for loose or missing hardware during PMCS on your tank’s mine
clearing blade, you need to look everywhere, crewmen.
There are six triangular access plates, NSN 5340-01-277-5670, on the blade’s
frame assembly. Crewmen generally check the hardware securing the access covers
on top of the frame assembly, but miss those underneath.
The bottom access covers
are important, too. If the hard-
ware loosens or falls out, the
shaft inside the pushbeam
shifts, letting the pushbeam
fall. That causes severe dam-
age to the mine clearing blade.
So, check all of the push
beam’s
hardware
during
PMCS. If any is loose or miss-
ing, the mine blade’s NMC
until repaired.
Check access plate hardware under frame assembly, too
T
he little things can make a big difference when it comes to PM on your Stryker,
drivers.
One such little thing is making sure the vehicle’s wheel nuts are tight. Simple,
sure, but important nonetheless.
One loose nut puts more strain
on its neighbors. They loosen
and, before you know it, you’ve
got a runaway tire.
Look closely at the wheel stud
nuts before operation. If you spot
any rust or shiny areas that indi-
cate a loose nut, report it. Your
mechanic will retighten the nuts
to 226-236 lb-ft.

M1-Series Tanks…
Stryker…
T
ry as you might, you can’t tow if the pintle on your M1-series tank won’t open.
And that’s what will happen if the pintle doesn’t get regular lubing.
Without lube, the pintle devel-
ops a severe case of lockjaw. And
if it won’t open, you can’t attach
the tow bar.
So lube the pintle semiannually
with WTR like it says in your LO.
Just make sure you wipe off the
grease fitting first to keep out dirt.
