original 107-7773 Machinery Engine Parts Diesel Injector 0R-8477 101-8673 127-8216 107-7733 for 3116 new injector original new injector

Engineered specifically for the 3116 diesel engine, this mechanical fuel injector is also compatible with related 3114 engine applications, ensuring a direct, OEM-type fit across a broad range of heavy-duty industrial machinery. The injector is built to deliver precise fuel metering and fine atomization, supporting stable idle quality, strong load response, and balanced cylinder output. Its heavy-duty construction is designed to withstand the continuous high-pressure demands of construction equipment, generators, and truck engine operations.

This replacement part covers a wide cross-reference range, simplifying inventory management for distributors and fleet operators. By restoring proper injection pressure and spray pattern, the injector helps recover lost engine power, reduce excessive black or white smoke, and improve overall fuel economy. It is intended for use in excavators, wheel loaders, motor graders, backhoe loaders, scrapers, track loaders, asphalt pavers, and compactors powered by the 3116 series engine.

To maintain long-term performance, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and keep the fuel tank free of sludge, rust, and water. Injectors should remain in sealed dry packaging until installation, and the nozzle tip should not be touched. If multiple injectors show uneven output or wear, replacing the full set is recommended for balanced engine operation.
