The Isuzu NQR71 Truck, a reliable workhorse in medium-duty applications, is powered by the robust 4HG1 engine. A critical component within this engine's fuel injection system is the Eccentric Shaft Gear, bearing part number 8-97088057-0. This precision-engineered gear is integral to the operation of the engine's fuel pump, accurately translating the rotation of the camshaft into the eccentric motion required to drive the pump's plungers. Its function is vital for ensuring the correct timing, pressure, and volume of fuel delivery to the cylinders.
Manufactured to Isuzu's exacting OEM standards, part 8-97088057-0 guarantees a perfect fit, optimal meshing with adjacent components, and long-term durability under high-stress conditions. A failure in this gear can lead to severe engine performance issues, including power loss, irregular operation, or a complete failure to start. Therefore, using this genuine replacement part is crucial for maintaining the 4HG1 engine's renowned fuel efficiency, performance, and reliability.
