The Perkins 3116 3114 fuel injector 107-7733 is engineered to deliver precision fuel metering and optimized fuel atomization for heavy-duty diesel applications. Built with heavy-duty construction and OE-style fitment, this injector supports consistent spray patterns and stable injection timing across demanding work cycles. It is designed as a direct replacement for the Perkins 3116 and 3114 engines commonly installed in excavators, wheel loaders, motor graders, track loaders, compactors, and asphalt pavers. Engine-specific matching ensures correct flow rate, pressure calibration, and electrical response for the original fuel system.

Multiple searchable cross-reference numbers, including 1077733, 127-8216, 1278216, 0R-8682, 0R8682, 107-7773, 1077773, CA1278216, CA0R8682, CA1077733, and CA1077773, simplify procurement and inventory lookup for diesel parts distributors, fleet maintenance companies, rebuilders, and repair shops. The injector is compatible with a broad range of Perkins-powered equipment, including 320B, 322B L, 322B LN, 325B L, 325B LN, M318, 924F, 928G, 938F, 950F II, 120H, 135H, D5M, D6M, IT24F, IT28G, IT38F, 613C II, 446B, 953C, 963B, AP-1000, and AP-1050. Wide coverage of compactor models such as CB-634, CB-634C, CP-533, CP-533C, CP-563, CP-563C, and the CS-531 through CS-583C series further extends its field service value.

Before installation, clean fuel and regular filter replacement are essential to prevent contamination and clogged nozzles. Injectors should be replaced as a matched set when possible, and protective caps must remain in place during storage and handling. After installation, operators should prime the fuel system, replace seals and O-rings, follow Perkins service manual torque specifications, and perform diagnostic tests for idle quality, acceleration, smoke level, and load performance. Common symptoms indicating injector wear include hard starting, rough idle, black or white smoke, power loss, high fuel consumption, engine knock, and misfire, often caused by poor atomization, uneven fuel delivery, or internal wear. Attention to proper installation procedures helps restore original engine performance and extend service life.
