The Perkins 3116 / 3114 fuel injector is identified by the authorized OE number 107-7733 and is fully interchangeable with the cross-reference numbers 1077733, 127-8216, 1278216, 0R-8682, 0R8682, 107-7773, 1077773, CA1278216, CA0R8682, CA1077733, and CA1077773. This multiple-number coverage allows parts distributors and fleet buyers to consolidate SKUs and simplify inventory across Perkins 3114 and 3116 diesel engine applications. Each injector is built with precision fuel metering, optimized atomization, and a heavy-duty body that matches the original equipment specification for consistent cylinder-to-cylinder delivery in demanding industrial duty cycles.
This injector is designed for Perkins 3114 and 3116 diesel engines used in excavators, wheel loaders, motor graders, track loaders, compactors, and asphalt pavers, including machine models such as M318, 320B, 320B L, 320B N, 320B S, 322B L, 322B LN, 325B L, 325B LN, 924F, 928G, 938F, 950F II, 446B, 953C, 963B, 120H, 120H ES, 120H NA, 135H, 135H NA, D5M, D6M, AP-1000, AP-1050, IT24F, IT28G, IT38F, 613C, 613C II, CB-634, CB-634C, CP-533, CP-533C, CP-563, CP-563C, CS-531, CS-531C, CS-533, CS-533C, CS-563, CS-563C, CS-573, CS-583, and CS-583C. Before installation, confirm the OE number, cross-reference number, and engine serial number, and note that some supplier databases link 1278216 to Perkins 3126B, 3126E, and C7 categories, which must be verified against the injector tag and original part number.
Common symptoms of a worn or failed injector include hard starting, rough idle, black or white smoke, power loss, high fuel consumption, engine knock, and misfire, typically caused by poor atomization, uneven fuel delivery, over-fueling, internal leakage, incorrect injection timing, clogged nozzles, or internal injector wear. For reliable service life, use clean diesel fuel, replace fuel filters regularly, prevent contamination, install injectors as a matched set when possible, store units with protective caps, and avoid mechanical damage during handling. After installation, clean the injector bore, replace seals and O-rings, follow the Perkins service manual torque specifications, prime the fuel system, check for leaks, and run idle, acceleration, smoke, and load performance tests.
