5-Ton Dump Trucks…

Hinges on Lube
W
hen you’ve unslung the ol’ grease gun, don’t forget to get a few shots off on the
dump bed hinge pins, operators.
Forget, and the pins rust. When
the bed is raised, the hinge is forced
to pivot on the rusty pins. A lot of
stress results, snapping the hinge
bolts or cracking the hinge itself.
Prevent that damage by giving
the hinge pins a few shots of GAA
semiannually or every 3,000 miles.
If operation is frequent or continu-
ous or you’re operating in severe
conditions, lube the pins weekly.

HMMWV…
Dear Half-Mast,
LO 9-2320-280-12 says to lube the tie rod ends on our
HMMWV every 3,000 miles or semiannually with GAA. Here in Iraq,
we feel this just isn’t enough.
The terrain here is very hard on tie rods. Sand and dirt make things
even worse. If the tie rods seize and break, we could lose steering.
Should we lube the tie rods more often?
SSG S.L.P.
Dear Sergeant S.L.P.,
Yes, you should.
The LO says hard time intervals can be shortened if your lube
is contaminated or if the vehicle is being operated under adverse conditions.
The
desert definitely qualifies!
Make sure you clean off both grease fittings on each tie rod end before lubing.
That’ll help keep sand out.
While you’re under the vehicle, take a close look at the
rubber boots at each end.
Look for cracks or tears that let lube out and sand in.
Tell your mechanic if you find any.
Lube tie rod ends here…
…and here with GAA
lube your
tie rods?
but
they’re not due
for
two more
months!
all this
heat and
sand
changes
things! I
need lube
more often
over here!
…or weekly in severe conditions
Lube hinge pins semiannually
or every 3,000 miles…
owww!
without lube, my
dump bed hinges
didn’t stand a
chance!!
