ISUZU D-MAX TFR RODEO CAMPO PANTHER 4JA1 4JA1-T 2.5L V-BELT DOUBLE PULLEY 7.2ML 100BAR HYDRAULIC POWER STEERING PUMP (OE: 470-03148 / 8-97084-953-0 / 8-97129-593-0 / 8-97331-940-0 / 8-97305-148-0)

Overview

The Isuzu D-Max / TFR 4JA1 Hydraulic Power Steering Pump (P/STG Pump Assembly 470-03148 / 8-97084-953-0 / 8-97129-593-0) is a commercial-grade hydraulic steering component engineered specifically for Isuzu D-Max, TFR, Rodeo, and light commercial utility pickup fleets powered by the Isuzu 4JA1 (2.5L) and 4JA1-T (2.5L Turbo) 4-cylinder direct-injection diesel engine (Isuzu D-Max 1st Gen, TFR54, Rodeo, Invader, Fuego, Panther, and Opel Campo commercial pickups, single/double cab work trucks, flatbed haulers, and fleet utility vehicles equipped with belt-driven hydraulic power steering systems). Built in the engine block bracket-mounted, 2-belt double V-belt pulley driven (102 mm OD) configuration, this precision hydraulic vane pump delivers a steady, calibrated hydraulic flow rate of 7.0 L/min at up to 100 bar operating pressure (7.2 ml/r displacement) directly to the power steering gearbox. Replacing a worn, whining, stiff, or leaking power steering pump eliminates heavy steering effort, cures steering wheel vibration and judder at engine idle RPM, prevents hydraulic oil cavitation/aeration, and restores smooth, effortless steering control under heavy commercial payloads and daily fleet operations.

Engineered to commercial fleet specifications verified against Malaysian commercial pickup and light transport standards for dependable workshop replacement, steering overhaul, and preventive fleet maintenance.
