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.

4.

Remove the filter by pulling the screwed-in 

bolt.

5.

Remove the O-ring from the plug.

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

Always fit a new O-ring to the plug and lightly 

lubricate the O-ring with oil.

2.

Fit the new filter in the valve block.

3.

Fit the plug (1).

4.

Tighten the plug to the specified tightening 

torque, see "Technical data". 

5.

Top up the system.

6.

Bleed the steering circuit of the front axle.

4.11 REMOVAL AND INSTALLATION, AIR DRYER FILTER ELEMENT

Note:

To be certain that the air dryer is functioning 

properly, the air reservoirs should regularly be 

checked for condensation. If more than the 

normal amount of water is drained off repeatedly, 

the air dryer element must be replaced. Under 

normal circumstances the element must be 

replaced at least once per year.

Removing air dryer filter element
1.

Vent the air dryer by allowing it to regenerate 

or by loosening the compressor line (1), so 

that the interior of the air dryer is 

depressurised.

2.

Remove the filter element by turning it anti-

clockwise using a filter strap spanner.

3.

Dispose of the drying element as if it were an 

oil filter.

4.

Clean the air dryer internally.

5.

Check the air dryer threaded connection (2) 

for damage and then lubricate it sparingly 

with grease.

Installing the air dryer filter element
1.

Lubricate the sealing ring of the new filter 

element sparingly with grease.

2.

Fit the filter element by manually tightening it 

until the sealing ring abuts. Then tighten the 

element by hand (approx. 1 turn).

3.

Fasten the compressor line (1).

4.

Pressurise the system and then check the air 

dryer for any air leaks.
