32 41 037 Removing and Installing/Replacing Power Steering Pump For Hydraulic Steering Gear With Dynamic Drive

32 41 037 Removing and installing/replacing power steering pump for power steering gear with Dynamic Drive (S63)





Note:
When replacing power steering pump:

Fluid reservoir must be replaced in event of metal abrasion, sluggish pump shaft or increased wear!

The filter integrated in the fluid 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 fluid reservoir as metallically glittering hydraulic fluid.

It is only necessary to replace the fluid 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!

Risk 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 tasks:
^ Draw off and dispose of hydraulic fluid from fluid reservoir
^ Remove expansion tank
^ Remove water cooler
