Power Steering Pump 0054669401
The 0054669401 Power Steering Pump, also known as Power Steering Pump 0054669401 0054669501, 0054669401 for MB E350, Power Steering Pump 0054669501 for E350 and Car Power Steering Pump 0054669401 0054669501, is a high-performance hydraulic vane pump engineered for Mercedes-Benz hydraulic power steering systems. Driven by the engine via a multi-rib belt pulley, the pump continuously supplies pressurized hydraulic fluid to the steering gear, providing smooth, precise, and consistent steering assistance while reducing steering effort under all driving conditions.
Manufactured to OE specifications, the pump features a precision-machined vane rotor, integrated pressure-limiting valve, and durable aluminum housing to ensure stable hydraulic pressure, low operating noise, and long service life. Every unit is pressure-tested and leak-tested before shipment to guarantee dependable performance and direct OE replacement compatibility.

Structural Composition
Aluminum Pump Housing：
High-strength die-cast aluminum housing provides excellent rigidity, corrosion resistance, and efficient heat dissipation.
Vane Rotor Assembly：
Precision-engineered rotor and sliding vanes generate stable hydraulic flow and pressure for consistent steering assistance.
Cam Ring：
Optimized cam profile improves volumetric efficiency while reducing internal wear and hydraulic pulsation.
Pressure Limiting Valve：
Built-in pressure relief valve protects the steering hydraulic circuit from excessive pressure during high-load steering conditions.
Drive Shaft Assembly：
Transfers engine torque efficiently to the rotor assembly for continuous hydraulic fluid circulation.
Bearing Assembly:
High-quality low-friction bearings ensure smooth rotation, reduce mechanical losses, and extend service life.
Shaft Seal System：
Premium oil seals prevent hydraulic fluid leakage and maintain stable internal operating pressure.
Hydraulic Ports：
OE-standard inlet and outlet connections provide secure integration with the original hydraulic steering system.

Installation and Usage Notes
Disconnect the vehicle battery before installation.
Inspect the steering rack, hydraulic hoses, reservoir, and fittings for wear or contamination.
Flush the hydraulic steering system if the previous pump has failed internally.
Use only the power steering fluid specified by the vehicle manufacturer.
Tighten all hydraulic fittings according to OE torque specifications.
Bleed the hydraulic system thoroughly after installation to remove trapped air.
Check for hydraulic leaks and abnormal operating noise.
Verify steering assistance during the initial road test.
Recheck the hydraulic fluid level after the first test drive.
Always confirm compatibility using the VIN number and OEM part number before installation.
