Genuine Shandong Kangda Fuel Injection Pump BH4QT90R9 (4Q355M-1) for Yunnei YN490 Engine

Genuine Shandong Kangda 4-cylinder fuel injection pump, model 4Q355M-1. Specifically engineered for the Yunnei 490  diesel engine, this high-precision mechanical pump carries the assembly code BQ2000. Shandong Kangda is a renowned OE manufacturer, and this pump is designed to provide the rugged reliability required for light trucks, agricultural machinery, and industrial power units that rely on the Yunnei series.

The SHA2168 serves as the heart of the engine’s fuel system, responsible for pressurizing diesel and distributing it to each of the four cylinders with exacting timing. Because it is a genuine Kangda product, the internal plungers and delivery valves are manufactured to extremely tight tolerances. This ensures that can maintain consistent injection pressure even under heavy load, which is critical for maintaining the YN490 engine’s torque curve and overall thermal efficiency.

If your vehicle is experiencing difficulty starting, erratic idling, or a significant loss of power, a worn injection pump is often the culprit. Replacing a failing unit with this brand new SHA2168 is the best way to restore your engine to factory-new performance levels. Unlike refurbished units, this new pump guarantees an optimal spray pattern and precise fuel metering, helping to reduce exhaust smoke and improve fuel economy. This genuine 4Q355M-1 assembly is factory-calibrated and ready for installation, ensuring your Yunnei 490 engine continues to deliver dependable service for years to come.
