ISUZU FORWARD FTR FVR FSR FRR 6HE1 6HH1 6HK1 HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (1-19500-533-0A / 1-19500-533-0 / 1195005330 / 475-05200 / JKC 05202)

Overview

The Isuzu 6HE1 / 6HH1 Hydraulic Power Steering Pump (P/STG Pump Assembly 1-19500-533-0A / 1-19500-533-0 / 1195005330) is a heavy-duty hydraulic steering component engineered for Isuzu Forward and medium-to-heavy commercial vehicles powered by Isuzu 6HE1, 6HH1, and 6HK1 diesel engines (FTR, FTR 800, FVR, FSR, FRR, and FVZ series cargo lorries, tippers, dump trucks, box vans, and refrigerated haulers equipped with gear-driven hydraulic power steering systems). Driven directly by the engine timing gear train, this high-performance 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 and vibration 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?

• Consistent High-Pressure Hydraulic Flow: Precision-machined internal rotor and vanes provide continuous, smooth hydraulic assistance even at low engine idling speeds, minimizing driver fatigue during tight maneuvers.

• Wear-Resistant Drive Gear: Induction-hardened gear teeth prevent pitting, backlash, and premature wear against the engine timing gear assembly.

• 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.
