M1000 HET Trailer . . .
Always lock the cover closed using
the clamping catch. If the catch won’t
close easily, look to see if the stop bar
is resting on the setscrew.
ne sure way to lose the use of a
rear landing leg on the M1000 HET
trailer is to let its cover get damaged.
While it’s true that a 70-ton tank track
will sometimes do a job on the cover
no matter what you do to prevent it,
most of the damage can be prevented.
Here’s how:
Keep the support leg cover closed
and latched completely when loading
or unloading a tank.
Make sure the stop bar—the raised
ridge under the cover—doesn’t rest on
the actuator nut setscrew when the
cover’s closed. The bar is there to keep
the nut from turning on its own and
lowering the support leg.
Lube actuator fitting monthly
Cover missing? Use canvas
or plastic as protection
Adjust nut so stop bar prevents
nut from unscrewing
Keep catch lubed and locked
Lubricate the actuator nut and the actua-
tor monthly as prescribed in the lubrication
chart on Pages 3-12 and 3-13 of TM 9-
2330-381-14.
The actuator has a grease fitting and needs
just a couple of pumps of GAA. But the
nut must be lubed by hand, so
clean off the
nut and surrounding area, removing old
grease and dirt. Then apply GAA on and
around the nut so it will turn freely. Don’t
overlube, ’cause it’ll just attract dirt, which
can gum up the works.
If the catch is broken, get it replaced
as soon as possible. Parts for the cover
and catch are found in Fig 44 of TM 9-
2330-381-24P. The cover, NSN 5340-
01-385-9861, costs almost nine times
as much as the catch, NSN 5340-01-
116-3348. So, it makes sense to re-
place the catch to save the cover.
Adjust the nut so the bar clears the
setscrew.
If a rear support leg cover is already
missing from your trailer, put some-
thing (piece of canvas, plastic, etc.)
over the top of the leg to keep rain and
dirt out until a replacement cover is
installed. Leaving the cover off can
result in a “frozen” leg that is almost
useless in supporting the trailer in
operation.
