8-97610800-0 Isuzu 6UZ1 / 6WG1 Engine High-Pressure Fuel Pump Coupling Assembly

Product Overview
8-97610800-0 is a genuine-quality high-pressure fuel pump coupling assembly (fuel pump drive coupler) designed for Isuzu 6UZ1 and 6WG1 series engines. This coupling assembly is installed between the engine and the high-pressure fuel pump, responsible for transmitting crankshaft power precisely to the high-pressure fuel pump. It is a critical drive component of the fuel injection system.

In demanding mining, earthmoving, and other high-load continuous operation environments, the fuel system is constantly subjected to high pressure and intense vibration. This coupling is engineered specifically for such harsh conditions, ensuring stable fuel supply to the injection system and sustained engine power output.

Installation Tips
Verify that the new coupling matches the old unit (part number 8-97610800-0) before installation.
Ensure proper alignment between the coupling, fuel pump drive shaft, and engine drive gear during installation.
Tighten the mounting bolts to the torque specifications recommended by the engine manufacturer.
After installation, start the engine and check for proper fuel pump operation and any unusual noise.
Regularly inspect the coupling for wear and replace if any abnormality is detected.
