Product Specifications:
The 3200690 is a heavy-duty, precision-engineered Common Rail Diesel Fuel Injector (Aftermarket Replacement) designed specifically for Caterpillar C6.6 engines and the compatible Perkins 1100 Series (1106D). These highly efficient powerplants are the workhorses of mid-sized construction equipment, including the popular 12M/120M motor graders, D6N track-type tractors, and 930H wheel loaders. Manufactured to verify against rigorous OEM testing protocols to ensure optimal fuel atomization, emissions compliance, and maximum torque output under heavy load.

👨🔧 Tech Notes & Installation Guide
-
💰 Why Replace the Full Set?
-
The Risk: Mixing a brand-new common rail injector with old, worn units on a 6-cylinder C6.6 engine causes severely uneven fuel delivery. This leads to Cylinder Power Imbalance (Engine Vibration, Drivetrain Stress, and Increased Fuel Consumption).
-
The Fix: Take advantage of our Volume Discounts to install a matched set of 6 units. This ensures uniform fuel pressure across the rail and restores smooth factory performance.
-
-
✅ Calibration & Installation:
-
These injectors are pre-calibrated on the test bench to match OEM flow standards. (Note: Depending on your specific ECM software version, entering the unique injector trim code into the system may be required during installation for optimal fuel mapping).
-
-
⚠️ Critical Cleaning Step:
-
The entire high-pressure fuel delivery system (tank, lines, and rails) MUST be thoroughly flushed to remove microscopic debris or metal shavings. Always install a brand-new, high-efficiency fuel filter to protect the precision control valves from scoring.
