4.4.2 Function description

The steering is not used
Pump 6 draws oil from the tank and sup-
plies the power steering servo with oil.
Because the steering is not used the oil
flows through the power steering servo,
the control module and the external hy-
draulics without resistance. If the external
hydraulics are used the pressure relief
valve A will reduce the pressure to 125
bar.
From the external hydraulics the oil re-
turns to the tank via collector block 5.
1. Power steering servo containing the
following:
A. Pressure relief valve
B. Safety valves
C. Control module
D. Oil pump
Connections on power steering servo
P. Unregulated input from hydraulic
pump for external hydraulics.
