Perkins original Perkins 111-7916 Fuel Injector Replacement for CAT 3408 3412 990 769D 773D Loader Engine  original new injector

The Perkins 111-7916 fuel injector is engineered as a direct OEM replacement for the Perkins 3412 engine series, including the 3412B and 3412C variants widely deployed across industrial and heavy-duty applications. Manufactured with precision-machined internal components, this injector delivers accurate fuel metering and consistent spray patterns, supporting stable combustion across demanding load profiles. It also serves as a reliable substitute for part number 0R-8479, giving operators a dependable option for fleet maintenance and engine overhaul programs.

Constructed from high-grade, corrosion-resistant materials, the 111-7916 injector is built to withstand high operating temperatures and harsh environmental conditions. Its heavy-duty construction and OEM-level dimensional accuracy ensure a precise fit and straightforward installation, minimizing downtime during service. Excellent atomization efficiency promotes more complete fuel burn, which contributes to improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions across continuous-duty operating cycles.

Suitable for generator sets, marine propulsion systems, oilfield drilling equipment, mining machinery, and other Perkins 3412-powered installations, the 111-7916 injector helps maintain stable engine performance and extend overall service life. To achieve optimal long-term results, operators should use high-quality diesel fuel, replace fuel filters on schedule, avoid water contamination, maintain proper fuel pressure, and conduct periodic injector testing while monitoring engine performance indicators.
