original 140-8413 Injector Fuel 1408413 107-1230 162-0212 for 3114 3116 Excavator Diesel Engine, Common Rail Fuel Injector  original new injector

The 140-8413 fuel injector is engineered specifically for the 3116 series diesel engine, providing precise metered fuel delivery into the combustion chamber to support stable combustion and reliable engine operation. Designed as a direct OE-type replacement, this injector assembly follows standard factory fitment dimensions and sealing geometry, allowing straightforward installation on 3114, 3116, and 3126 engine applications. The unit is commonly used on equipment such as the 938G Wheel Loader and IT38G, and is interchangeable with cross reference numbers 1408413, 0R-8867, OR-8867, OR8867, 127-8220, 7E-6193, 9Y-4982, and 127-8230. Buyers are advised to confirm the original injector number, engine serial number, engine arrangement number, and equipment model before purchase to ensure correct fitment.
Featuring heavy-duty construction and stable atomization performance, the 140-8413 injector helps reduce incomplete combustion, excessive smoke, poor starting behavior, and rough running when installed as a matched replacement. Its strong sealing design supports consistent injection pressure and helps protect the engine from performance loss caused by weak injection, nozzle wear, or internal leakage. This injector is suitable for individual replacement, full engine set replacement, export sales, distributor inventory, fleet maintenance programs, and diesel repair shop use across industrial, construction, marine, generator, and mining applications running compatible 3116 engine configurations.
Proper maintenance is essential for long injector service life. Operators should monitor fuel cleanliness, replace fuel filters on schedule, drain water separators regularly, inspect fuel tank condition, and check oil quality to prevent contamination-related injector damage. During installation, professional service is recommended, sealing rings should be replaced, and torque values should follow the official service manual. After installation, inspect for fuel leakage, unstable idle, excessive smoke, misfire, abnormal fuel pressure, and performance under load. Common symptoms such as hard starting, rough idle, black or white smoke, engine knock, power loss, high fuel consumption, fuel smell, oil dilution, or excessive exhaust temperature may indicate injector issues, and cylinder balance testing, spray pattern inspection, return flow testing, and sealing inspection are recommended to restore balanced engine operation.
