The Power Steering Oil Pump Assembly with OEM numbers 1-19500561-2 / 1195005612 is a verified direct-fit replacement for ISUZU CXZ series heavy-duty trucks equipped with the 6WF1 diesel engine. This hydraulic pump is a critical component of the power steering system, responsible for generating and maintaining hydraulic pressure to assist steering effort, ensuring stable and responsive steering control under heavy loads and complex road conditions.
- Real Bench Test Data: Maximum working pressure verified at 130 bar; operating speed range 500–3,600 r/min — tested on hydraulic test bench under simulated steering load conditions.
- Proven Durability: Rated for continuous operation in 3-axle heavy trucks and container tractors. Net weight 5.26 kg — confirmed by 100% quality inspection.
- Installation Success Rate: Standard OEM mounting configuration — 2 installation holes, 20-tooth pump gear — direct bolt-on fitment confirmed across ISUZU CXZ/CYZ/EXZ truck applications.
- OEM Cross-Reference Verified: Replaces 1-19500561-0 / 1195005610, 1-19500561-1 / 1195005611, 1-19500561-3 / 1195005613.
- 100% Pre-Delivery Testing: Every unit undergoes pressure and flow testing before shipment.
- Heavy/Stiff Steering — especially at low speeds, during parking, or tight turns
- Whining or Groaning Noise — when turning the steering wheel, worsening at full lock
- Squealing on Startup — or during sharp turns, indicating pump struggling to maintain pressure
- Fluid Leak — reddish-brown or amber puddle near the front of the vehicle
- Jerky or Inconsistent Steering Response — the wheel feels sometimes loose, sometimes tight
