Fuel Pump Drive Gear
Detroit Diesel

The fuel pump drive gear is fundamental for transmitting rotational force from the engine to the fuel pump, enabling proper fuel delivery for combustion. With an outer diameter of 96.50 mm and a base diameter of 85.70 mm, it is designed for a precise fit within the pump assembly. The 48-tooth configuration with a 20-degree pressure angle ensures smooth engagement and efficient power transfer, reducing vibration and noise during operation. Crafted from high-grade steel, this gear offers excellent durability and resistance to wear, which is essential given the high rotational speeds in heavy-duty diesel engines. Proper alignment and maintenance of this gear are vital for maintaining accurate fuel timing, directly impacting engine power, efficiency, and emissions. Source One Parts Center recommends this gear to ensure reliable operation and longevity of the fuel injection system in demanding service conditions.
