Perkins original Perkins 140-8413 Fuel Injector 107-7733 127-8211 0R-8677 for 3116 3126 Excavator Engine, Diesel Fuel Injector  original new injector

The Perkins 140-8413 1408413 Fuel Injector GP-Fuel is an OE-type replacement unit designed for the Perkins 3116 Series diesel engine, with additional listing coverage for the Perkins 3114 and 3126 engine applications. Authorized cross reference numbers include 0R-8867, OR-8867, 127-8220, 7E-6193, 9Y-4982, and 127-8230, enabling direct interchange for distributors, fleet operators, and repair shops managing mixed inventory. The injector is commonly fitted to the Perkins 938G Wheel Loader and IT38G, and is also used across construction machinery, industrial diesel engines, loaders, trucks, generator sets, marine auxiliary engines, and earthmoving equipment utilizing compatible Perkins 3116 configurations.

This injector assembly delivers metered diesel fuel into the combustion chamber with stable atomization, strong sealing performance, and a heavy-duty structure built to standard OE-style fitment. It supports engine protection by helping reduce incomplete combustion, black or white smoke, poor starting, rough idle, and uneven running. Precision fuel delivery and consistent spray pattern help maintain balanced cylinder performance under load, making the 140-8413 suitable for individual replacement, full engine set replacement, export sales, and distributor inventory.

Professional installation is recommended, and sealing rings should be replaced during injector installation. Torque and adjustment values must follow the official Perkins service manual. After installation, inspect for leakage, unstable idle, excessive smoke, misfire, fuel pressure issues, and performance under load. Fuel cleanliness, filter condition, water separation, and tank integrity are critical to injector service life, since contaminated fuel, dirty filters, water ingress, or rusty tanks can damage the nozzle and cause hard starting, power loss, high fuel consumption, or engine knock. Final fitment should be verified with the original injector number, engine serial number, engine arrangement number, and equipment model.
