Power Steering Pump 56110R40A01

The 56110R40A01 Power Steering Pump, also known as Power Steering Pump 56110R40A01, Power Steering Pump 56110R40A01 for HONDA, 56110R40A01 56100R40P05 for HONDA and 56100R40P05 56100R40305 Car Power Steering Pump, is a professional-grade hydraulic steering component engineered to deliver precise and reliable power assistance. Designed specifically for Honda 2.4L i-VTEC 4-cylinder powertrain platforms, this premium vane-type pump ensures optimal and consistent hydraulic pressure delivery to the steering rack, facilitating effortless maneuvering, exceptional high-speed stability, and responsive vehicle handling.

Manufactured in strict accordance with original equipment (OE) standards, this power steering pump features a direct-fit replacement design that ensures seamless installation. It effectively eliminates steering stiffness, isolates hydraulic pulsations, minimizes system whine, and restores the factory-smooth steering performance of your vehicle.

OE-quality direct replacement for original part number 56110-R40-A01 / 56110-R40-A02

Delivers precise hydraulic pressure for predictable and linear steering assist

Constructed with a premium, lightweight aluminum alloy housing for superior heat dissipation • Includes a pre-installed, factory-balanced 7-rib serpentine belt pulley to prevent belt slip

Equipped with a 90-degree aluminum inlet tube flange with premium O-ring seal

100% computerized pressure, flow, and leak-tested under simulated real-world loads

Micro-finished internal rotor and vanes minimize friction and eliminate steering shudder

Advanced high-temperature lip seals prevent fluid migration and ensure a zero-leak lifespan

Tailored specifically for the Honda K24Z 2.4L engine platform to guarantee perfect belt alignment

Aluminum Pump Housing: Lightweight, high-tensile strength aluminum alloy housing engineered for precise engine block mounting and optimal thermal management.

Pre-Installed 7-Rib Pulley: A factory-pressed, 7-groove metal drive pulley, precision-balanced to eliminate vibration, shaft runout, and premature serpentine belt wear.

Rotor and Vane Assembly: High-precision internal rotor and floating vane mechanism designed to maintain stable hydraulic flow across the entire engine RPM range.

Removable Inlet Flange: A top-mounted, 90-degree angled aluminum suction tube flange secured by a retention bolt, fitted with an anti-leak rubber O-ring.

High-Pressure Outlet Port: Machined threaded discharge port designed for a robust, fluid-tight flare-nut connection with the vehicle's high-pressure line.

Premium Seal Package: Heavy-duty, temperature-resistant internal seals and O-rings engineered to withstand extreme hydraulic pressures without degrading.

Low-Friction Bearings: High-load internal roller bearings that support effortless drive-shaft rotation and substantially extend the pump's operational life.

Disconnect the vehicle battery before commencing the replacement procedure.

Always verify the specific vehicle sub-model, engine code (K24Z), and VIN to guarantee application compatibility.

Caution: This pump includes a pre-installed pulley. Do not attempt to adjust, remove, or apply impact tools to the pulley shaft, as this will destroy the precise internal clearances of the aluminum pump.

Thoroughly drain and flush the entire power steering system (including the steering gear and lines) to remove old, contaminated fluid, metal shavings, and sludge before mounting the new pump.

Clean the vehicle's remote plastic reservoir thoroughly; inspect and clear any debris from its internal fine-mesh filter screen to ensure unobstructed fluid flow.

Crucial (Fluid Type): Use ONLY genuine Honda-approved Power Steering Fluid. Do not use standard Automatic Transmission Fluid (ATF) or generic multi-vehicle fluids, as their chemical composition will degrade the internal seals and cause rapid pump failure.

Replace the O-ring on the 90-degree intake flange during installation to prevent air from being sucked into the system (which causes foaming and loud whining).

Bleeding Procedure: Elevate the front wheels off the ground. Fill the reservoir to the max line, and with the engine OFF, slowly cycle the steering wheel fully from lock-to-lock at least 20 times to purge trapped air. Top off fluid, start the engine, and inspect for foaming.

Perform a comprehensive road test to verify smooth, linear steering assistance, and recheck all fittings for hydraulic fluid weeping.
