WARNING: Danger to life! Mount securing fixture for vehicle on lifting platform to prevent the vehicle from slipping off or tilting down.

Secure engine in installation position to prevent it from falling down.

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 plugs.

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.

Necessary preliminary tasks:

Version with active front steering: Disconnect plug connection (1).

Release hose clamp (4) and detach suction line from power steering pump.

Release banjo bolt (3) and disconnect pressure line for power steering from power steering pump.

Release banjo bolt (2) and detach pressure line for Dynamic Drive from power steering pump.

Installation:

Replace all sealing rings.

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