HEMTT . . .
HEMTT Tankers . . .
orget or ignore hydraulic fluid PM on your M977, M984E1 or M985 HEMTT
crane and you’ll soon be left with a truck that’s NMC.
Low fluid or a clogged filter will eventually stop a crane from lifting, which
leaves you out of commission until a fix is made.
Even before the crane stops working, it will jerk when it moves, as dirty or
contaminated fluid bypasses a clogged filter.
So, eyeball the fluid level on the hydraulic reservoir’s sight glass before every
operation. The fluid level should be between ADD and FULL after the vehicle
is warm.
If the fluid level’s
right and the crane still
doesn’t work or jerks
during operation, let
your mechanic know.
He’ll check the crane
and hydraulic system
troubleshooting in-
structions in TM 9-
2320-279-20-1.
hen you HEMTT tanker drivers button up for the
road, remember to secure the rear doors so they don’t become
wings as you’re trucking down the road.
Securing them is no problem if the door latches work properly. Close the doors
on your tanker and make sure the latches hold the doors shut. If they don’t, get
your mechanic to repair or replace them.
Some soldiers take no chances with door latches by locking the two hinged
hasps, NSN 5340-01-360-0950, and a hasp staple, NSN 5340-01-361-1467, that
come on most tankers.
If your tanker doesn’t have the hasps and staple, mount the hasps using 10
solid rivets, which are about
1
/
4
inch
in diameter and
1
/
2
inch long. There is no
NSN for this
rivet, so check
locally for a
replacement.
The staple is
mounted using
four rivets,
Once the hasps and staple
are installed, use a
padlock, NSN 5340-00-
158-3805, to secure the doors.
Fluid level OK?
