HINO DUTRO 300 RANGER FC TOYOTA DYNA J05C J05D 20T RH 14.5ML 130BAR HEAVY DUTY HYDRAULIC POWER STEERING PUMP (OE: 44350-1340 / S44350-1340 / 44350-1341 / 44310-2401)

Overview

The Hino Dutro / Ranger FC J05C Hydraulic Power Steering Pump (P/STG Pump Assembly 44350-1340 / S44350-1340 / 44350-1341) is a commercial-grade hydraulic steering component engineered specifically for Hino Dutro, 300 Series, Ranger FC, and Toyota Dyna light-to-medium commercial transport trucks powered by Hino J05C (4.7L / 5.3L) and J05D 4-cylinder diesel engines (FC series, Dutro 300, and Dyna commercial 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, 20-Tooth (20T) helical drive gear, standard 2-bolt flange mounting configuration, this hydraulic vane pump delivers a steady, calibrated hydraulic flow rate of 11.0–13.0 L/min at up to 130 bar operating 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 for dependable workshop replacement, steering system overhaul, and preventive chassis maintenance.

Always verify your original gear tooth count [20T] and rotation direction [RH] prior to ordering.)

Why Choose Our Commercial Truck Parts?

• Calibrated High-Pressure Hydraulic Flow (14.5 ml/r, 130 bar): Precision-machined internal rotor and vanes provide continuous, smooth hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Induction-Hardened 20T Drive Gear: High-grade heat-treated 20-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.
