NISSAN DIESEL UD RESONA BIG THUMB CW54 CW52 RE8 RF8 26T LH ROUND TYPE SMALL SHAFT HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (14670-97178 / 1467097178 / 475-97361)

Overview

The Nissan Diesel UD CW54 / RE8 Hydraulic Power Steering Pump (P/STG Pump Assembly 14670-97178 / 475-97361) is a heavy-duty hydraulic steering component engineered for Nissan Diesel (UD) Resona, Big Thumb, and heavy commercial transport trucks powered by Nissan RE8 and RF8 V8 diesel engines (CW54, CW54L, CW52, and CWA54 series heavy cargo lorries, dump trucks, tippers, concrete mixers, and prime movers equipped with gear-driven hydraulic power steering systems). Built in the Left-Hand (LH) rotation, 26-Tooth (26T) gear, Round Type Small Shaft (SH) configuration, this 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 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 26T Drive Gear: Induction-hardened 26-tooth gear resists pitting, gear backlash, and premature wear against the engine timing gear train.

• Integrated Flow Control & Relief Valve: Factory-calibrated internal pressure relief valve ensures stable line pressure while preventing high-pressure hose 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.
