NISSAN DIESEL UD BIG THUMB QUON CW CD CG GW PF6 GE13 RG8 26T DOUBLE CARTRIDGE TANDEM HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (14670-96413 / 1467096413 / 26 TEETH DUAL PUMP)

The Nissan Diesel UD 26T Double Cartridge Hydraulic Power Steering Pump (Tandem Dual Vane P/STG Pump Assembly 14670-96413 / 1467096413) is a heavy-duty hydraulic steering component engineered for Nissan Diesel (UD) Big Thumb, Quon, and heavy commercial multi-axle transport trucks powered by Nissan PF6, GE13, RG8, and MD92 heavy diesel engines (CW, CD, CG, CWB, and GW series multi-axle cargo lorries, heavy tippers, dump trucks, concrete mixers, prime movers, and heavy haulers requiring dual-circuit hydraulic flow). Featuring a dual-cartridge (tandem vane) internal architecture driven directly by an induction-hardened 26-tooth (26T) helical drive gear, this high-flow pump delivers calibrated, independent high-pressure hydraulic streams to feed the primary steering gearbox alongside auxiliary steering circuits (such as twin-steer axles or secondary assist systems). Replacing a worn, whining, cavitating, or leaking double-cartridge pump eliminates heavy or unresponsive steering, cures low-speed shuddering, prevents cross-circuit pressure loss, and restores smooth, effortless steering control under maximum gross combination weights.

Engineered to heavy commercial fleet specifications for dependable workshop replacement, steering system overhaul, and preventive chassis maintenance.

Why Choose Our Commercial Truck Parts?

• Precision Dual-Cartridge Hydraulic Flow: Dual rotor and vane sets ensure continuous, uninterrupted hydraulic volume to both primary and auxiliary steering circuits, eliminating heavy spots during tight maneuvering.

• Induction-Hardened 26T Drive Gear: High-grade heat-treated gear teeth resist pitting, gear chatter, and premature backlash against the engine timing gear train.

• Integrated Flow Control & Dual Relief Valves: Factory-calibrated pressure regulation ensures stable line pressure while preventing high-pressure line failure during full steering lock.

• High-Grade Oil Seals: Heat- and oil-resistant internal seals prevent hydraulic steering fluid from contaminating the engine oil crankcase.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch across Peninsular and East Malaysia.
