3D84E Fuel Pump Drive Gear, High-Precision Alloy Steel

The 3D84E diesel pump gear is a critical transmission component in the engine's fuel system, primarily driving the fuel injection pump and ensuring fuel is delivered to the combustion chamber at the correct time and pressure. Made of high-strength alloy steel, this gear undergoes precision machining and surface hardening, offering excellent wear resistance and load-bearing capacity.
During operation, the gear maintains precise meshing with the crankshaft or intermediate gear, ensuring stable operation of the fuel injection pump, thereby maintaining engine injection timing and combustion efficiency. The optimized tooth profile design and rigorous machining process effectively reduce vibration and noise, extending the life of the fuel pump and engine.

• High-quality materials, durable and reliable: Made of high-strength alloy steel, heat-treated and surface-hardened, it offers excellent wear resistance and fatigue resistance, extending service life.
• High-precision tooth profile design: Precision machining ensures stable tooth meshing, effectively reducing vibration and noise during operation and ensuring smooth transmission.
• Stable injection timing: The gear closely meshes with the fuel pump, ensuring synchronized operation of the injection pump, maintaining fuel injection timing, and improving engine combustion efficiency. 
• Strong Corrosion and Oil Resistance: Surface treatment enhances corrosion resistance, making it suitable for diesel, engine oil, and high-temperature environments, preventing premature wear and damage.
• Easy Installation and Maintenance: Equipped with synchronous positioning marks, installation and alignment are simple, significantly reducing assembly difficulty and maintenance costs.
