NISSAN DIESEL UD BIG THUMB RESONA CW520 CWB520 CW459 CWB450 PF6 PF6T RF8 HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (14670-96264 / 1467096264 / 14670-96277 / 1467096277)

Overview

The Nissan Diesel UD PF6 / CW520 Hydraulic Power Steering Pump (P/STG Pump Assembly 14670-96264 / 1467096264) is a heavy-duty hydraulic steering component engineered for Nissan Diesel (UD) Big Thumb, Resona, and heavy commercial transport trucks powered by Nissan PF6, PF6-T, PF6-TA, and RF8 diesel engines (CW520, CWB520, CW459, CWB450, CK, CD, and CV series heavy cargo lorries, dump trucks, tippers, concrete mixers, prime movers, and logging haulers equipped with gear-driven hydraulic power steering systems). Driven directly by the engine timing gear train (Right-Hand / RH rotation), this high-capacity hydraulic vane pump generates continuous, calibrated fluid pressure to supply the power steering gearbox. Replacing a worn, whining, or leaking power steering pump eliminates heavy or stiff steering, cures steering wheel shuddering and vibration at low engine idling RPM, prevents hydraulic oil aeration/cavitation, 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?

• Consistent High-Pressure Hydraulic Flow: Precision-machined internal rotor and vanes provide continuous, smooth hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Wear-Resistant Drive Gear: Induction-hardened gear teeth prevent pitting, backlash, and premature wear against the engine timing gear assembly.

• 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.
