HINO RANGER FF FD GD FT175 KL LB EH700 6.4L 18T RH 3-HOLE FLANGE HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (44310-1561 / 443101561 / 44300-1561 / 18 TEETH)

Overview

The Hino EH700 18T 3-Hole Hydraulic Power Steering Pump (P/STG Pump Assembly 44310-1561 / 443101561) is a heavy-duty hydraulic steering component engineered specifically for Hino Ranger, FF, FD, GD, FT175, KL, KR, and LB series commercial transport trucks powered by the Hino EH700 6.4L 6-cylinder diesel engine (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, 18-Tooth (18T) drive gear, 3-Hole flange mounting 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?

• Calibrated High-Pressure Hydraulic Flow (80–85 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 18T Drive Gear: High-grade heat-treated 18-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.
