original 140-8413 Mechanical Fuel Injector Assembly for 3116 3114 3126 Excavator Diesel Engine 1408413 0R-8677 107-7733 127-8211 Aftermarket Parts original new injector

Engineered as a direct OE-style replacement for 3116 series diesel engines, the 140-8413 Fuel Injector delivers dependable fuel atomization and precision metering for heavy-duty industrial operations. This injector assembly is also commonly listed for 3114 and 3126 engine platforms, though final fitment must be verified using the original injector number, engine serial number, and engine arrangement number. Cross-reference numbers include 1408413, 0R-8867, OR-8867, OR8867, 127-8220, 7E-6193, 9Y-4982, and 127-8230, ensuring wide compatibility across replacement scenarios.

Designed with a heavy-duty structure and strong sealing performance, the 140-8413 injector supports stable atomization, precision fuel delivery, and improved combustion quality when correctly installed. It helps reduce common diesel operating issues such as incomplete combustion, black or white smoke, poor starting, and rough idle. Typical equipment applications include the 938G Wheel Loader, IT38G, construction machinery, generator sets, marine auxiliary engines, commercial trucks, and earthmoving machines powered by compatible 3116 engine configurations. This makes it suitable for individual replacement, full engine set overhaul, export distribution, fleet maintenance, and diesel repair shop inventory.

To maintain optimal injector performance, operators should focus on fuel cleanliness, timely filter replacement, water separation, and oil monitoring. Symptoms such as hard starting, engine knock, power loss, high fuel consumption, or oil dilution may indicate injector wear, poor atomization, or sealing failure. Recommended diagnostics include fuel pressure testing, cylinder balance testing, spray pattern inspection, and return flow analysis.
