It Takes a 5-Ton
Use only a 5-ton truck to pull M1022
and M1022A1 dolly sets. TM 9-2330-
379-14&P for the basic M1022 dolly
set says you can use a 2

-tonner. But
forget that—the deucer can’t maintain
enough air pressure for both air brake
systems.
M1022 and M1022A1 Dolly Sets . . .
Problem is, your weight will break
the T-fitting that connects the brake
system’s air hoses into the valve. A
busted valve means no brakes.
So, for safety’s sake, stay off the
valve.
If you can’t exercise the equipment,
smear a thin coat of GAA on the rods.
If your dolly set is going to sit un-
used for more than a month, coat rods
with GAA, then wrap them with wa-
terproof paper, NSN 8135-00-753-
4662. Use moisture-resistant sealing
tape, NSN 7510-00-852-8180, to hold
the paper in place.
Avoid Tight Turns
Ease off on too-tight turns. In a too-
tight turn, the least you’ll get for your
trouble is bent tie rods.
The dolly set turns shorter than the
truck when being backed. While your
truck is still turning, the tie rods on the
dolly set are bending and breaking. If
your turn is too tight, you could dump
whatever the dolly set is carrying.
Protect Hydraulic Cylinders
Corrosion ruins cylinder rods. It pits
the rod so badly that seals can’t pre-
vent fluid leaks. If the leaks go to Class
III, your dolly set is NMC.
So, stop corrosion long before it gets
to pitting by exercising your equipment
each week. Exercising spreads a thin
coat of hydraulic oil on the cylinder
rods.
Watch Your Step
Keep your boots off the dolly set’s
emergency relay valve. The valve
makes a convenient footrest during
visual checks and services.
