Caterpillar original Engine Injector 20R-3247, Replacement for OEM 392-0225, Cross Reference 20R-1269, for 3516C 3512C 3508B 3512B 3516B C35 Excavator original new injector

Precision-built to Caterpillar’s strict fuel system engineering specifications, the 20R-3247 remanufactured diesel fuel injector serves as a direct-fit replacement component for CAT 3512B and 3512C heavy-duty engine platforms, including marine and generator-dedicated variants in the CAT 3500 series. It carries verified cross-compatibility with reference numbers 236-9007 (2369007) and remanufactured part identifier 10R-7075 (10R7075), simplifying parts sourcing for global aftermarket and industrial maintenance teams.

Manufactured to OEM quality standards with industrial-grade, high-durability construction, the injector delivers accurately timed, precisely metered diesel fuel and fine atomization to promote complete, efficient combustion. This calibrated design boosts engine power output and throttle response, cuts fuel consumption and particulate exhaust emissions, stabilizes idling, and reduces unplanned downtime by supporting consistent performance under fluctuating load conditions.

The component is engineered for use across mining, marine propulsion, oil and gas, industrial manufacturing, heavy construction, and power generation sectors, supporting continuous-duty prime power systems, emergency backup generators, and heavy mobile worksite equipment. To maximize service life and performance, installation must follow official Caterpillar service protocols, with routine maintenance including clean diesel fuel, regular filter replacement, and periodic injector testing.
