hink you’re ready to hook up
your M1088 or M1088A1 FMTV
tractor to a trailer? Maybe not, if
you haven’t checked the fifth
wheel’s position.
The fifth wheel must be in the
full-forward—or front—position
in order to hook up to a trailer or
pull one. Otherwise, you’re likely
to bend the frame.
Use the rear position only
when the tractor-trailer rig is
being loaded onto a ship.
Reprinted from PS 64 (1958)…
Sliding fifth wheel must be in the front position
before coupling M1088/M1088A1 tractor to any
trailer. Failure to comply may result in damage to
equipment.
Additionally, add this CAUTION about tractor-trailer
operation in cross-country conditions:
Do not exceed the 22-percent grade limitation
while operating the M1088/M1088A1 tractor. Failure
to comply may result in damage to equipment.
In other words, don’t drive over hills that will force
the fifth wheel to bend or tilt in order to stay hooked to
the trailer.
Fifth wheel in full
forward position?
Add this CAUTION
to Para 2-39(a) of
TM 9-2320-366-10-1
until it is updated…
