Bum Hardware Problem
The reports also note grease fittings that won’t take grease because the bolt that
holds the pins and bushings in place has worked loose.
Seems the pins separate from the bushings, which causes the pins and bushings
to rub. Soon the grease holes don’t line up right and grease can’t get where it needs
to be. A loose bolt can also cause the seal to malfunction, letting in dirt and dust.
A new bolt is available that will solve this problem. Make notes in TM 9-2330-
381-24P and put these new bolts to work now:
NSN 5306-01-472-3328, which is Item 4, Fig 29; Item 6 in Fig 30; and Item 6
in Fig 32.
Part number SW32291-3, which is Item 19, Fig 30. Order it on DD Form 1348-
6, using CAGE 98255 with RIC AKZ.

M1000 HET Semitrailer…
Lubing Right
Help out yourself and your unit by doing the lube job right, starting now.
Chapter 3 of TM 9-2330-381-14 has the mandatory lube instructions for the
M1000. Eyeball Page 3-11, Step 13, for the platform grease fittings vital to the pins
and bushings. These fittings are lubed monthly
under normal conditions.
TM 9-2330-381-14
Page 3-1, para 3-2, step 1:
If a lubrication fitting will
not accept grease, check to
make sure that everything is
properly tightened. If loose,
tighten appropriate parts. If
the lubrication fitting still
will not accept grease, notify
your supervisor.
That translates
into
two
problems
for you who are
facing your first
5-year services…
Until they
do, add this
note to Step i
in Para 3-2 on
Page 3-1 in
the -14 TM…
o
Lubricate more often
during constant use and
twice as often
in extreme
dust and sand conditions.
o
Clean the grease fittings
with dry cleaning solvent
and dry them off before
using the grease gun.
Here’s the
extra lubing
info that
you need
to know…
Even more expense than is
necessary, since the pins range
in price from about $200 to
more than $1,000.
Lots more maintenance
time than is necessary.
Early results
from the first
5-year services
performed on upper
and lower steering
plate bearings and
lower suspension
bearings on M1000
semitrailers are
now in…
…and they show
that the trailers
aren’t
getting
enough grease.
…that disassembly
for the service
is extremely
difficult
and
time-consuming.
Reports show the
lack of lubrication
damages
pins and
bushings used in the
struts and steering
cylinders so
badly…
The headshed will
also make another
TM change to make
pulling the 5-year
service as easy as
possible.
