AUXILIARY CIRCUIT
The AUXILIARY CIRCUIT used on the 00 MODEL C50SS has been designed and installed
for the purpose of operating the hydraulic function of the agitator and outriggers. This
function is that of the agitator rotation for mixing the material in the hopper and operation of
the outriggers.
The flow and pressure requirements for the auxiliary circuit is met by employing the second
stage or section of the same tandem pump used on the swing tube shift circuit. With the
engine running and throttle set to maximum
RPM , the flow from the tandem pump is directed
to a three (3) spool directional control valve.
When the valve lever is moved away from hopper the agitator will rotate in a forward direction
as hydraulic fluid is directed to that side of the motor. The rotation can be reversed by
moving lever in other direction. For the outriggers, one lever controls the leg on the right side,
while the other lever controls the left side leg.
A flow control valve is installed in the hydraulic line for forward rotation. The purpose of this
valve is adjust the flow to that particular side of the motor which in turn regulates the rotation
speed. Turn flow control knob clockwise to decrease speed.
A relief valve is installed in the directional control valve and is set at 1500 PSI. This is used
to protect the system against excessive pressure.
