Application Type |
Heavy Duty Diesel / Mechanical Unit Injector Replacement for Caterpillar 3116 Series |
The Caterpillar 3116 fuel injector 0R-3389 is engineered to deliver precise fuel metering and fine atomization for the inline 6-cylinder, 4-stroke Caterpillar 3116 diesel engine with 6.6 L displacement and turbocharged-aftercooled aspiration. Built as a heavy-duty mechanical unit injector, it supports rated engine speeds of 2800 rpm and serves marine power configurations ranging from 224 bkW to 261 bkW. The injector GP is designed for CAT 3116-focused applications and is compatible with a rich catalog of cross-reference numbers including 4P-2995, 0R-8471, 7E-8952, 7E-8729, 0R-4374, 0R-3006, 127-8216, 127-8218, 107-7735, 1565023, 0R-8682, 127-8213, 127-8222, and 127-8205, covering related 3114, 3116 DIT, 3126, 3126B, and C7 injector family applications.
Available as genuine Cat Reman, remanufactured, new aftermarket, replacement, or rebuilt, the 0R-3389 injector meets professional repair-shop requirements for engine overhaul, fleet maintenance, and export-ready spare part inventory. Sales unit is one piece, with a complete 6-cylinder engine typically requiring six injectors. The injector is suitable for medium-duty trucks, buses, marine vessels, excavators, wheel loaders, generator sets, industrial power units, mining support equipment, and agricultural equipment. Buyer groups including truck repair shops, fleet maintenance companies, bus operators, marine diesel repair companies, heavy equipment dealers, generator service companies, distributors, wholesalers, and B2B spare parts sellers benefit from its search-friendly identification and broad OE-number compatibility.
Reliable operation depends on clean diesel fuel, regular fuel filter replacement, water separator drainage, air intake maintenance, and correct injector seating. Common failure causes such as fuel contamination, water in fuel, poor filtration, overheating, incorrect torque, damaged seals, and mismatched injector sets can be prevented through systematic maintenance and injector balance testing. Diagnostic actions including fuel pressure checks, return flow measurement, leak-off testing, cylinder balance evaluation, compression testing, spray quality inspection, and fuel system cleanliness verification help identify weak injection, internal leakage, air ingress, uneven delivery, over-fueling, and poor atomization, ensuring long service life and consistent engine performance in demanding industrial environments.
