HINO RANGER FF FD GD KL LB EH700 6.4L RH WITH RESERVOIR TANK HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (44300-1670 / 443001670 / 44300-1670B )

Overview

The Hino EH700 Hydraulic Power Steering Pump with Reservoir Tank (P/STG Pump Assembly 44300-1670 / 443100-1670B / W/Tank) is a heavy-duty hydraulic steering component engineered specifically for Hino Ranger, FF, FD, GD, KL, and LB series commercial transport trucks powered by the Hino EH700 6.4L 6-cylinder diesel engine (FF172, FF177, FD, GD, KL, KR, and LB series cargo lorries, wooden body trucks, tippers, dump trucks, and box vans equipped with gear-driven hydraulic power steering systems). Built as a complete unit featuring an integrated hydraulic fluid reservoir tank (W/Tank) in the Right-Hand (RH) rotation configuration, this hydraulic vane pump delivers a steady, calibrated flow rate of 10.0 L/min at up to 105 bar operating pressure directly to the power steering gearbox. Replacing a worn, leaking, or whining power steering pump and rusted oil reservoir eliminates heavy or stiff steering, cures steering wheel shuddering at low engine idling RPM, prevents fluid aeration and 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?

• Complete Assembly with Integrated Tank (W/Tank): Pre-assembled with a dedicated fluid reservoir, eliminating external tank hose leaks and simplifying workshop installation.

• Calibrated High-Pressure Hydraulic Flow (16.0 ml/r, 105 bar): Precision-machined internal rotor and vanes provide continuous 10.0 L/min hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Induction-Hardened RH Drive Gear: High-grade heat-treated gear teeth resist 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 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.
