The CAT 20R-0759 is an industrial-grade precision diesel fuel injector purpose-built for Caterpillar 3412 series 4-stroke V12 industrial diesel engines. It fits heavy-duty CAT equipment including 777D dump trucks, D11T bulldozers, 992K wheel loaders, 3512 generators and 3512B industrial pumps, serving construction, mining, marine and general industrial scenarios. Manufactured to strict Caterpillar OEM specifications, it meets certified CAT quality requirements and is produced under ISO 9001 and CE certified standards for reliable performance under demanding workloads.
This injector supports both mechanical and electronically controlled injection configurations, fitted with a multi-hole high-pressure nozzle operating at a typical 2000–2200 bar pressure range. Following high-pressure diesel injection principles, its calibrated needle opens to deliver finely atomized fuel, while the 150°–160° spray angle and precision-machined tight tolerances ensure uniform combustion distribution. Precise injection timing boosts fuel efficiency, reduces particulate emissions, and sustains stable engine output under continuous heavy loads.
Made from high-grade corrosion-resistant steel, the 20R-0759 resists wear and corrosion in harsh operating conditions and is remanufacturable to support fleet cost reduction. It requires a calibrated 25–35 Nm installation torque, with pre-installation seat and fuel line cleaning recommended, plus nozzle inspection every 500 operating hours. It is an ideal OEM-spec replacement for heavy equipment fleets, CAT service centers and industrial parts suppliers.
