4.10 REMOVAL AND INSTALLATION, OIL FILTER IN FLUID FLOW CONTROL

VALVE BLOCK OF EMAS SYSTEM

Drained steering oil must not be re-
used.
Make sure that during filling and
bleeding the reservoir always
remains filled with oil in order to
prevent the pump from drawing in air
which would cause foaming in the
oil.
Air in the hydraulic system may
cause serious damage to the
steering pump. Air in the hydraulic
system can cause the steering gear
to jam occasionally.
If the hydraulic system contains air,
a squealing sound will be heard
when the steering wheel is turned
and pressure is built up.
In the case of serious foaming, the
steering oil should be completely
drained.

Removing the filter of the fluid flow control
valve block
1.

Place a receptacle under the valve block.

2.

Remove the plug (1) from the valve block.

3.

Turn a bolt (M6) into the filter.

Remove the filter by pulling the screwed-in
bolt.

Installing the filter of the fluid flow control
valve block
