NISSAN DIESEL UD CONDOR CMB88 CMF88 CPB15 FE6 FE6T 21T RH SQUARE TYPE BIG SHAFT HEAVY DUTY HYDRAULIC POWER STEERING PUMP P/STG PUMP (14670-Z5660 / 14670Z5660 / 475-04250 / 475-04345 / 21 TEETH)

Overview

The Nissan Diesel UD CMB88 / FE6 Hydraulic Power Steering Pump (P/STG Pump Assembly 14670-Z5660 / 14670Z5660) is a heavy-duty hydraulic steering component engineered for Nissan Diesel (UD) Condor CMB88, CMF88, and CPB15 (Old Model) commercial transport trucks powered by Nissan FE6 and FE6-T 6.9L 6-cylinder diesel engines (CMB88, CMF88, and CPB15 series cargo lorries, wooden body trucks, tippers, dump trucks, and box vans equipped with gear-driven hydraulic power steering systems). Built in the Right-Hand (RH) rotation, 21-Tooth (21T) drive gear, Square Type Big Shaft (3-Hole mount) configuration, 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/cavitation, and restores smooth, effortless steering control under heavy commercial payloads.

Engineered to heavy commercial fleet specifications verified against Malaysian commercial truck supplier standards for dependable workshop replacement, steering overhaul, and preventive chassis maintenance.
