ISUZU FORWARD GIGA 6BG1 6BG1T 10PB1 10PA1 HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (1-19500-187-0 / 1-19500187-0 / 1195001870 / 475-03924)

Overview

The Isuzu 6BG1 & 10PB1 Hydraulic Power Steering Pump (P/STG Pump Assembly 1-19500-187-0 / 1195001870) is a heavy-duty hydraulic steering component engineered for Isuzu Forward, Giga, and heavy commercial vehicles powered by Isuzu 6BG1, 6BG1-T, 10PB1, and 10PA1 diesel engines (FTR, FVR, FVM, CXZ, CXM, and EXZ cargo lorries, dump trucks, tippers, concrete mixers, prime movers, and heavy machinery). Driven directly by the engine timing gear train, 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, and restores smooth, effortless steering control under heavy commercial payloads.

Engineered to heavy commercial fleet and industrial machinery specifications for dependable workshop replacement, steering system overhaul, and engine 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 steering effort during tight maneuvering.

• 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.
