Caterpillar original 10R-8996 Mechanical Fuel Injector for 3116 C3116 Engine, Replaces 127-8216 127-8218 0R-8469 Excavator Truck Diesel Parts original new injector

Engineered for Caterpillar 3116 and 3126 diesel platforms, the CAT Fuel Injector 10R-8996 delivers OE-style fitment and consistent fuel metering performance for medium-duty truck, marine, and industrial engine applications. The injector accurately meters, pressurizes, and atomizes diesel fuel into the combustion chamber at the correct timing and spray pattern, while sealing combustion pressure and controlling internal leakage. Compatible with the 3116 inline 6-cylinder engine and the 3126 marine and industrial engine series, this injector supports proper injection timing across MUI and HEUI 2-valve fuel system configurations.

Constructed with heavy-duty internal components, the unit is designed to withstand the demanding operating conditions found in fleet service, engine rebuild programs, generator repair, and mining or construction equipment maintenance. Reference cross numbers 10R8996 and 1734647 allow global cross-reference recognition, making it straightforward to source for international repair operations across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia. Approximate physical dimensions of 8.8 inches in length and 4.8 inches in height align with the original equipment envelope.

Proper installation practices extend service life: replace fuel filters on schedule, drain the water separator, keep the air intake system unrestricted, and avoid mixing injectors with different calibration levels. Common failure symptoms such as hard starting, rough idle, white or black smoke, engine knock, power loss, high fuel consumption, and elevated exhaust temperature can be addressed by checking fuel pressure, return rates, cylinder balance, injector sealing, and turbocharger performance. Store units in sealed packaging and install only in a clean repair environment.
