HYDRAULICS
In this chapter a short overview of the hydraulic system
that needs te be installed on a tractor will be given.
1.2.1
PRESSURE RELIEF VALVE
A pressure relief valve is mounted to the add-on part
of the open center manifold (Figure 3). This pressure
relief valve must be set to the maximum allowable
control pressure of the steering system. The default
setting of the pressure relief valve is about 180 bar.
Determine the maximum pressure of the steering
system before mounting the manifold. Follow the next
steps:
•
Mount a pressure gauge, by making use of
a t-piece in the pressure line between the
hydraulic pump and the steering orbitrol.
•
Steer the front wheels to one side and
keep steering until the maximum pressure
is reached.
•
Read out the value on the pressure gauge.
After mounting the manifold. Set the maximum
pressure of the pressure relief valve, equal to the
maximum pressure of the steering system. Follow the
next steps:
•
Mount a pressure gauge, by making use of a t-
piece in the pressure line between the
hydraulic pump and the manifold.
•
Loosen the locking nut of the pressure relief
valve.
•
Loosen the pressure relief valve two turns
counter clockwise.
•
Steer the front wheels to one side, using the
Left/Right buttons of the CRx/ ROS.
Keep steering until the maximum pressure is
reached.
•
Read out the value on the pressure gauge.
•
Adjust the pressure relief valve until the
pressure is equal to the pressure it was before
mounting the manifold.
•
Secure the pressure relief valve with the
locking nut.
