32 41 037 Removing and installing/replacing power steering pump for hydraulic steering gear with Dynamic Drive (N63)





Note:
When replacing power steering pump:

Oil reservoir must be replaced in event of metal abrasion, sluggish pump shaft or increased dirt contamination!

The filter integrated in the oil reservoir can only absorb a limited amount of foreign particles. If the filter clogs, the hydraulic system can no longer be sufficiently protected.

Metal abrasion is perceived in the oil reservoir as metallically glittering hydraulic fluid.

It is only necessary to replace the oil reservoir because of leaks (e.g. at hose connections) only in the event of the unavoidably high ingress of dirt.





Warning!
Danger of poisoning if oil is ingested/absorbed through the skin!

Danger of injury if oil comes into contact with eyes and skin!

Important!
Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Seal off hydraulic lines with seal plugs.





Necessary preliminary work:
^ Draw off and dispose of hydraulic fluid from oil reservoir
^ Remove expansion tank
^ Remove water cooler
^ Remove drive belt for alternator





Disconnect plug connections (1) and (2).

Release hose clamp (3) and detach intake pipe from power steering pump.

Release union nut (4) and disconnect pressure line for hydraulic steering from power steering pump.

Tightening torque 32 41 4AZ (for hydraulic steering).

Installation Note:
Replace all sealing rings.

Make sure hydraulic lines are laid without tension and with sufficient distance to adjoining components.

Align intake pipe by way of marking to connection on power steering pump.





Release banjo bolt (1).

Tightening torque 32 41 3AZ.

Release nuts (2) and place expandable hose (3) to one side.





Release bolts (1) and remove holder (2) and power steering pump towards bottom.

Tightening torque 32 41 3AZ





After installation:
^ Fill and bleed hydraulic system
^ Check pipe connections for leaks
^ If necessary, carry out initial Dynamic Drive operation
