Winch and pintle fittings on your
deployable universal combat earth-
mover get overlooked because
they’re in the back of the vehicle.
Out of sight, out of mind.
But without lube, the winch’s
fairlead rollers can seize up. That
puts extra wear and tear on the
winch cable when it rides over the
rollers.
After you’ve greased the fairlead
rollers, grease the pintle.
If you forget to lube the pintle
every 250 hours or 3 months like
TM 5-2430-200-10 says,
rust
freezes it into position.
If the pintle can’t turn, a twisting
or tipping trailer can ruin a lunette
quick-like.
Without lube, the
block’s sheaves, trun-
nion and thrust bear-
ings can seize up.
That causes excessive
wear and tear on the
crane hoist cables and
hook block sheaves.
For smooth crane operation, lube the hook block with
GAA monthly or every 100 hours like it says on Page 1-4-9
of TM 5-3810-307-24-1-1.
Eight grease fittings on the 621B scraper often get overlooked because
they’re located behind the wheels. The fittings lube the brake camshafts.
Without lube, the camshafts
will bind—usually with the
brakes on. Then the brakes drag,
the linings glaze, and you can
have a tire fire on your hands.
So keep brake camshafts lubed
during scheduled services. Two
fittings are behind each wheel.

Hmmph!
O
perators, pumping grease into the fittings on your construction and material-
handling equipment isn’t a problem. The problem is finding all fittings.
You’re
getting
warmer!
If I don’t
get
lubed,
I
don’t
work!
