ith 10 bogies (axles) to maintain,
mechanics, what you don’t need is
damage caused by dirt that chews up
brake lines and suspension cylinder
seals on your M1000 HET trailer.
But that is what will happen if your
operators don’t keep the bogie bottoms
clean and you don’t keep the suspen-
sion cylinder’s wiper seal in place.
M1070 HET Winch Bracket
T
he mounting brackets of the M1070 transporter’s dressed winch assembly,
shown in Fig 216 of TM 9-2320-360-24P, now have NSNs. Get Item 22 with

PLS Air Horn
T
hink your PLS’s electric horn isn’t loud enough? With your commander’s
OK, you can now order an air horn kit, NSN 6350-01-460-5600. Installation
instructions come with the kit.

Then coat the outer metal shell with
Loctite or something similar. Then tap the
ring back into place in the groove of the
packing nut.
Don’t let the adhesive dry on the cylin-
der piston. It’ll just attract dirt.
Problem is, field conditions can loosen
the seal, so it does no good at all.
So, eyeball the cylinders on each bogie.
If the wiper seal is not securely in place at
the bottom of the cylinder, look at it
closely. If it’s not damaged, clean it with
P-D-680 dry cleaning solvent, NSN 6850-
00-281-1985.
As for the wiper seal on the sus-
pension cylinder, it’s there to keep
the cylinder surface clean and to
prevent dirt from scouring the oil
seal at the top of the cylinder.
Each of those 10 bogies collects lots
of dirt or mud during operation, mainly
because the bottom of the bogie is like
a pan. What goes into the “pan” stays
there—and turns into a concrete-like
substance that wears out the air brake
lines.
Operators must make sure the bogie
bottoms are free of dirt and mud after
every operation. Pressurized water
will remove most of the gunk, but a
little elbow grease may be needed
to get it all out from around the air
lines.
Clean dirt or mud from bogie
"pan" after each mission.
