Engineered specifically for Caterpillar 3116 and 3114 diesel platforms, this OE-style fuel injector delivers precision fuel metering and optimized atomization to support stable combustion across demanding duty cycles. Heavy-duty internal components and tight manufacturing tolerances help maintain consistent injection pressure, balanced cylinder contribution, and reliable cold-start performance in excavators, wheel loaders, motor graders, compactors, and asphalt pavers operating in harsh industrial environments.
The injector is designed as a direct replacement for authorized OE numbers 107-7733, 127-8216, 0R-8682, and 107-7773, with additional cross references CA1278216, CA0R8682, CA1077733, CA1077773, and 107-7732, enabling distributors, fleet maintenance teams, and rebuild shops to consolidate inventory across multiple Caterpillar machine families including the 320B, 322B, 325B, M318, 924F, 928G, 938F, 950F II, 120H, 135H, D5M, and D6M.
Prior to installation, technicians should confirm the part number and engine serial, clean the injector bore, replace seals and O-rings, follow Caterpillar torque specifications, prime the fuel system, and verify idle quality, acceleration response, smoke level, and load behavior. Routine use of clean diesel, regular filter replacement, and matched-set replacement further extend injector service life.
