NISSAN DIESEL UD TRUCKS RESONA CWA CW CK CD CV PE6 PE6T 11.7L 23T RH SQUARE FLANGE HYDRAULIC POWER STEERING PUMP (OE: 475-03380 / 47503380 / 14670-97367)

Overview

The Nissan Diesel UD PE6 Hydraulic Power Steering Pump (P/STG Pump Assembly 475-03380 / 14670-97367) is a commercial-grade hydraulic steering component engineered specifically for Nissan Diesel / UD Trucks Resona, CWA, CW, CK, CD, and CV series heavy commercial transport trucks powered by the Nissan Diesel PE6 (11.7L) and PE6T turbo inline-6 diesel engines (heavy cargo lorries, wooden body trucks, tippers, dump trucks, prime movers, concrete mixers, and heavy haulers equipped with gear-driven hydraulic power steering systems). Built in the Right-Hand (RH) rotation, 23-Tooth (23T) helical drive gear, heavy-duty square 4-bolt flange mounting configuration, this precision hydraulic vane pump delivers a steady, calibrated hydraulic flow rate of 11.0 L/min at up to 105 bar operating pressure (13.0 ml/r nominal displacement) directly to the heavy-duty power steering gearbox. Replacing a worn, whining, stiff, or leaking power steering pump eliminates heavy steering effort, cures steering wheel shuddering and judder at engine idle RPM, prevents hydraulic oil cavitation/aeration, and restores smooth, effortless steering control under heavy commercial payloads.

Engineered to heavy commercial fleet specifications for dependable workshop replacement, steering system overhaul, and preventive chassis maintenance.

Why Choose Our Commercial Truck Parts?

• Calibrated High-Pressure Hydraulic Flow (13.0 ml/r, 105 bar): Precision-machined internal rotor and vanes provide continuous, smooth 11.0 L/min hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during heavy payload maneuvers.

• Induction-Hardened 23T RH Drive Gear: High-grade heat-treated 23-tooth gear profile resists gear tooth pitting, backlash, and premature wear against the engine timing gear train.

• Heavy-Duty Square Flange Housing: Rigid cast housing ensures structural alignment and eliminates leakage or casing warping under heavy continuous hydraulic load.

• Integrated Flow Control & Relief Valve: Factory-calibrated internal pressure relief valve ensures stable line pressure while preventing high-pressure line bursts during full steering lock.

• High-Grade Oil Seals: Heat- and oil-resistant internal seals prevent hydraulic steering fluid from leaking into the engine oil crankcase.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch across Peninsular and East Malaysia.
