Basic Installation and Trouble Shooting Guide
If the transmission is equipped with a A-5010 Roadranger valve, see the Air Systems Troubleshooting
Guide, TRSM-0920, for operation and assembly instructions
.
Operation
The range shift air system consists of an air filter,
regulator, air valve, control valve, range air cylinder
which
is built into the auxiliary housing, fittings,
and connecting lines.
Range shifts can only be made
when the gear
shift lever is in, or passing through, neutral. Thus,
the range desired can be pre-selected while the
shift lever is in a gear position. As the lever is
moved through neutral, an actuating plunger in the
shift bar housing releases the inter-lock piston
allowing it to move to the range position selected.
Constant regulated air is supplied to the "S"
port of air valve and to the "IN" port of range con-
trol valve. With control button down, the control
valve is open, and air passes through control valve
and to the "P" port of slave valve. This permits air
from the constant supply to flow through the low
range port in slave valve to the air cylinder in aux-
iliary housing. Air at the cylinder moves the shift
piston and shaft to the rear to engage the low
range gear.
With the control button up, the control valve is
closed, and air is removed from end port of slave
valve. This permits movement of the air valve
poppet; air from the constant supply to flow
through the high range port of the slave valve and
to the high range port of range cylinder cover in
auxiliary housing. The shift piston and shaft are
moved forward to engage the high range or direct
gear.
When the control button is moved from one posi-
tion to another, air from the previously charged
Iine exhausts through the breather in range control
valve.
