HINO 700 PROFIA CAMC P11C F21C 27T RH ROUND TYPE 28.0ML 140BAR HEAVY DUTY HYDRAULIC POWER STEERING PUMP / P/STG PUMP (OE: 44310-1610 / 44310-E0C20 / 44350-1610)

Overview

The Hino / CAMC P11C Hydraulic Power Steering Pump (P/STG Pump Assembly 44310-1610 / 44350-1610) is a heavy-duty hydraulic steering component engineered specifically for Hino 700, Profia, and CAMC heavy commercial transport trucks powered by Hino P11C (10.5L) and F21C (New Model) diesel engines (heavy cargo lorries, dump trucks, tippers, concrete mixers, and prime movers equipped with gear-driven hydraulic power steering systems). Built in the Right-Hand (RH) rotation, 27-Tooth (27T) helical drive gear, Round Type flange (TSA configuration), this high-output hydraulic vane pump delivers a steady, calibrated hydraulic flow rate of 17.0 L/min at up to 140 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.

Why Choose Our Commercial Truck Parts?

• Calibrated High-Pressure Hydraulic Flow (28.0 ml/r, 140 bar): Precision-machined internal rotor and vanes provide continuous, smooth 17.0 L/min hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Induction-Hardened 27T Drive Gear: High-grade heat-treated 27-tooth gear profile resists gear tooth pitting, backlash, and premature wear against the engine timing gear train.

• Integrated Flow Control & Relief Valve: Factory-calibrated 140-bar 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.
