Application Type

Engine-Compatible Replacement / Authorized OE Cross Reference

Engineered specifically for the 3500 series, the 20R-1283 fuel injector is a direct-fit replacement for 3512B, 3508B, 3508C, 3516B, and 3516C diesel engines. The authorized cross-reference numbers 20R-1283, 386-1776, 392-0224, 0R-3539, 10R-2826, 158-5076, 192-2816, and 249-0746 allow the injector to be specified against genuine part catalogs, ensuring correct engine compatibility and avoiding sizing or calibration mismatches common with non-listed substitutes.

Each unit is built with precision atomization, accurate fuel metering, and OEM-calibrated injection timing to support optimized combustion efficiency and lower emissions. The injector assembly features high thermal tolerance, corrosion-resistant internal components, and proven durability under heavy load applications. It consistently delivers the precise amount of atomized diesel fuel into the combustion chamber, maintaining stable engine performance across marine propulsion systems, mining haul trucks, oilfield power units, and industrial generator sets.

Routine maintenance, including fuel filter replacement, leak inspection, and injector performance tests, is straightforward, and the injector follows standard installation steps—relieving fuel system pressure, cleaning the injector bore, replacing seals, and applying manufacturer torque specifications before priming and testing. When the engine shows black or white smoke, reduced power, or higher fuel consumption, the 20R-1283 provides a reliable, engine-matched restoration solution for 3512B and related 3500 series platforms.
