Hint!:
In case the wheels of the tractor are steering,
when the hydraulics of the tractor are operated;
a checkvalve should be mounted in the load
sense line from the manifold. The non-return
valve should let oil pass from the manifold to
the check valve/pump and should block in
opposite direction.
Hint!:
A shuttle valve for CNH tractors can be provided
by Raven Europe (part no. 13348001014) or the
local CNH dealer (part no. 82018814).

HYDRAULIC INSTALLATION OPEN CENTER
The manifold v3 open center consists of the standard
load sense manifold v3 with an add-on open center
part (Figure 8). Ensure the add-on is mounted the
correct way.
The pressure line that normally runs from the hydraulic
pump to the steering orbitrol, should be connected to
the P of the add-on open center part. Then connect a
line between P1 of the manifold and the pressure line
of the orbitrol. Connect the T of the manifold to a tank
inlet (Figure 9Figure 9 and Figure 10).
Connect the hoses leading from the orbitrol to A1 and
B1 on the manifold. Connect the hoses to the steering
cylinders to A and B of the manifold (Figure 9Figure 9
and Figure 10Figure 10).
