Product Specifications:
Engineered specifically for the rigorous demands of trenching, lifting, and continuous heavy earthmoving, the 3264700 is a premium aftermarket Common Rail Fuel Injector. Precision-calibrated for the highly utilized CAT C6.4 diesel engine (the robust powerplant driving the massive 320D, 321D, and 323D series excavators), this unit aggressively targets sluggish hydraulic response, severe exhaust smoke, and engine stalling under peak breakout loads. Featuring advanced internal flow dynamics and precise nozzle atomization, it ensures a true plug-and-play installation. Heavy equipment operators and independent mechanics can completely bypass expensive dealership ECU diagnostic delays, instantly restoring optimal fuel delivery and maximized digging torque to keep construction projects strictly on schedule.

👨🔧 Tech Notes & Installation Guide (FAQ)
Q: Why should I replace the full set of 6 injectors on my CAT C6.4 engine?
A: Operating heavy excavators with a failing injector causes massive common rail pressure drops and severe cylinder washing. This leads directly to violent engine shaking under heavy hydraulic digging loads, increased DPF clogging, and a critical loss of earthmoving power. We highly recommend utilizing our Volume Discounts to install a fully synchronized set of 6 units to ensure perfectly matched cylinder firing and restore maximum factory breakout force.
Q: Does the 3264700 injector require IMA coding?
A: No. This unit is strictly calibrated on advanced DCI test benches to perfectly match official OEM nominal flow data. Because its physical delivery quantities are tightly controlled within standard factory tolerances, your heavy equipment’s ECU will utilize its built-in self-adaptive learning (fuel trim) to automatically synchronize the injection. You get a true plug-and-play installation without needing manual dealer trim code entry.
Q: What is the critical cleaning step before installation?
A: Construction site environments expose fuel systems to extreme dust and abrasive contaminants. You must thoroughly flush the entire high-pressure fuel rail system and install brand-new OEM-spec fuel filters before cranking the engine to prevent immediate internal valve scoring and firmly protect your warranty.
