Pump Housing:

High-strength metal alloy housing provides excellent structural rigidity and efficient heat dissipation.

Rotor and Vane Assembly:

Precision-engineered rotor and sliding vanes generate consistent hydraulic pressure for smooth steering assistance.

Cam Ring:

Optimized internal cam profile ensures stable hydraulic flow and efficient pump operation.

Drive Shaft Assembly:

Transfers engine power to the internal pumping mechanism with high rotational accuracy.

Bearing System:

High-quality bearings reduce friction, improve rotational stability, and extend service life.

Shaft Seal Assembly:

Premium oil seals effectively prevent hydraulic fluid leakage while maintaining internal pressure.

Hydraulic Inlet and Outlet Ports:

OE-standard hydraulic connections ensure proper integration with the steering hydraulic circuit.

Disconnect the vehicle battery before starting the installation.

Inspect the steering rack/gearbox, hydraulic hoses, reservoir, and fittings for wear, aging, or contamination.

Flush the entire hydraulic steering system thoroughly if the previous pump experienced internal mechanical failure.

Replace contaminated fluid with manufacturer-recommended power steering fluid (e.g., VW G 004 000 / ATF equivalent).

Install the pump and torque all mounting bolts according to OE torque specifications.

Ensure all hydraulic inlet and outlet connections are securely tightened to prevent fluid leaks or air entry.

Bleed the steering system thoroughly (turn steering wheel lock-to-lock with wheels raised) to remove all trapped air before starting the engine.

Check the entire system for hydraulic leaks after initial setup.

Verify smooth steering operation and listen for abnormal pump noise during the test drive.

Recheck and top off the hydraulic fluid level after road testing.
