NISSAN DIESEL UD CONDOR PKD211 PKD214 PKC211 PKD411 JP251 FE6 FE6T FD6 21T RH SQUARE TYPE HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (14670-Z5572 / 14670-Z5701 / 14670Z5572 / 14670Z5701 / 21 TEETH)

Overview

The Nissan Diesel UD FE6 / FD6 Hydraulic Power Steering Pump (P/STG Pump Assembly 14670-Z5572 / 14670-Z5701) is a heavy-duty hydraulic steering component engineered for Nissan Diesel (UD) Condor, JP, and commercial transport trucks powered by Nissan FE6, FE6-T, FE6-TA, FD6, and FD6-T 6-cylinder diesel engines (PKD211, PKD214, PKC211, PKD411, JP251, LK, MK, and PK series cargo lorries, wooden body trucks, tippers, dump trucks, and box vans equipped with gear-driven hydraulic power steering systems). Built in the Right-Hand (RH) rotation, 21-Tooth (21T) helical drive gear, Small Head / Square Type flange configuration, this hydraulic vane pump delivers a steady, calibrated 10.0 L/min fluid delivery at up to 110 bar pressure directly to 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 verified against Malaysian commercial truck supplier standards for dependable workshop replacement, steering overhaul, and preventive chassis maintenance.

Why Choose Our Commercial Truck Parts?

• Calibrated High-Pressure Hydraulic Flow (12.8 ml/r, 110 bar): Precision-machined internal rotor and vanes provide continuous, smooth 10.0 L/min hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Induction-Hardened 21T Drive Gear: High-grade heat-treated 21-tooth gear profile resists gear tooth pitting, 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 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.
