USE THE
RIGHT
FLUID
USE THE
RIGHT
FLUID
N
ever use the same hydraulic fluid
in the FMTV’s air-hydraulic power
unit that you use in the hydraulic
reservoir for the winch or crane.
Use only MIL-H-5606 OHA or
Royco 756 in the air-hydraulic
power unit. Anything else will plug
the system check valves, making the
unit useless until the fluid is changed
and the valves are cleaned.
Use only OE/HDO-10 or OEA in
the hydraulic reservoir for the winch
or crane. Anything else will cause
poor performance or damage to the
components.

I
f fuel and air lines and hydraulic hoses lie too close to high heat sources like the
engine turbocharger exhaust pipe or exhaust manifold, you need to move them now
to prevent fires.
Look at the fuel and air lines that run near the exhaust manifold just to the left of
the secondary fuel filter on the passenger side of the engine.
Those lines must not touch the exhaust
manifold! Use an electrical tiedown strap
to pull the lines away from the manifold
by securing them to the water line run-
ning nearby.
Tiedown strap, NSN 5975-00-570-
9598, will do the job. Use more than one
strap if necessary.
Next, look at the hydraulic lines com-
ing from the power steering reservoir
next to the firewall. Those lines cannot
touch the turbocharger exhaust pipe.
Use tiedown strap, NSN 5975-00-
156-3253, to secure the lines as close
to the firewall as possible. This strap
is longer to secure more lines, but you
still may need to use more than one.
