the housing after the bleeding process has been

carried out as described above.

Switch off the engine and remove the blocks from

the steering axle.

4. Checking the oil level :

The oil level should be checked at operating

temperature at intervals of 5000 - 6000 kms( 3000-

3600 miles) or 100 - 120 operating hours.

4.1 Oil check on stationary engine :

In order to establish that no air is sucked in when

the engine is started, it must first be established

whether oil loss has occurred when the engine is

stationery.Therefore, the container should be filled

with so much oil that the oil level is approximately

1 to 2 cm above the upper marking on the oil

dipstick.

4.2 Oil check on running engine :

The oil level falls slightly when the engine is

running since the oil requires a pressure of

approximately 2 to 4 bar to flow through the

steering unit as a result of the resistance to flow.

The oil should therefore once again be topped up

so that the oil level lies constantly at the upper

marking. The engine can then be switched off

again. If this oil level is exceeded, then this is a

sign that there is still air in the oil.

5. Changing the oil and Filter

It is recommended to change the oil when the

steering gear or pump or both the units are repaired

or replaced. The filter in the oil reservoir should

also be replaced and the lines cleaned at this time.

When the soiled filter cartridge is removed, the

bottom opening must be closed immediately while

removing from the filter support to prevent dirty

oil in the filter cartridge running back into the

reservoir and entering the oil circuit.

6. Inspection Recommended

The ZF hydraulic ball and nut steering in short

form with pump should be inspected in the

installed condition, corresponding to the intervals

laid down in the following table, and also

depending on the vehicle application, by an

inspector in the workshops of the vehicle

company.

Apart from installing a new filter this inspection

also entails a functional test of the entire unit and

the necessary replacement of new parts.

It is not necessary to remove the steering unit

and pump from the vehicle for the first and second

inspection, unless defects have been established,

which then, of course, necessitate the removal of

the steering unit or the pump.

In the case of the third inspection we recommend,

due to traffic safety reasons, that the steering unit

and pump should be checked for correct function

and wear.

For this purpose they must be removed from the

vehicle, dismantled and the mechanical

transmission parts should be checked for cracks.

Note :

If oil loss is apparent, check for leaks and

repair if necessary.Repairs to the steering gear

must only be carried out in authorised service

stations.
