Dear Half-Mast,
We service the M1000
heavy equipment transporter
(HET) in our units. Is there
a directive or message to
put fire resistant hydraulic
(red) oil in the semitrailer’s
hydraulic system? I can’t find
a technical manual change or
update that says so.
Mr. Dave Keilly

Dear Mr. Keilly,
You can use MIL-H-46170, Type II,
hydraulic (red) fluid oil in place of Type
I (yellow) hydraulic fluid. Both are Fre
resistant and you can substitute one fluid
for the other, since the dye doesn’t cause
any difference in the fluid’s performance.
Use NSN 9150-01-131-3325 to get a
5-gal can of Type II (red) hydraulic fluid
or NSN 9150-01-158-0462 to get a 55-gal
drum of Type I (yellow) hydraulic fluid.
This is spelled out in this bulletin online:
Swivel Lunette
Get
your
CO’s
approval
to
replace the trailer’s original lunette
with a swivel lunette that comes
with NSN 2540-01-557-0056. The
swivel lunette makes lining up the
trailer with the truck’s towing pintle
a whole lot easier—especially in
rough terrain or crappy weather.
Mount the new lunette into the old
lunette’s recess.
Landing Leg Assist Lever
It’s no secret the landing legs on both
trailers are a bear to raise and lower
into position. NSN 5340-01-557-0024
gets an assist lever that makes raising
and lowering the legs easier. The lever
gives you more leverage to operate the
legs and can be released from its locked
position all in one motion. By the way,
the assist lever Fts into position without
drilling or modiFcations.
Hope this helps.
