Details
Caterpillar 10R-1284 / 10R1284 Fuel Injector for 3512B Engine Industrial Product Overview The Caterpillar 10R-1284, commonly written as 10R1284, is a heavy-duty diesel fuel injector assembly associated with Caterpillar 3512B-series engine applications. Designed for demanding industrial diesel operating environments, this injector is used as part of the engine fuel delivery and combustion system, where accurate fuel metering, injection timing, atomization quality, and consistent cylinder-to-cylinder fuel delivery are critical to engine performance. The 3512B engine platform is widely associated with high-output industrial applications, including power generation, marine propulsion or auxiliary power, petroleum operations, mining equipment, and other heavy-duty installations. Because Caterpillar engine configuration varies according to serial-number prefix, arrangement number, rating, application, emissions configuration, and production period, 10R-1284 compatibility should always be verified against the engine serial number, injector number removed from the engine, and applicable Caterpillar parts information before ordering or installation.

Caterpillar 3512B 20R-1264 Electronic Fuel Injector Product Detail Page

Product Overview

The 20R-1264 / 20R1264 electronic fuel injector is a heavy-duty diesel fuel injection component associated with Caterpillar 3500-series electronic engine applications, including the CAT 3512B.

Caterpillar officially identifies 20R-1264 as a Cat Reman Electronic Fuel Injector designed to deliver high-pressure fuel into the engine cylinder. Caterpillar's current parts information lists applications including 3512B, 3508B and 3516B engines across generator-set, marine, industrial and petroleum categories.

The 3512B is a V12 heavy-duty diesel engine platform used for continuous-duty and high-load power applications. Depending on the particular 3512B configuration, Caterpillar documents electronic unit injection/EUI fuel systems and ADEM electronic engine control.

Important Fitment Notice: Caterpillar 3500-series engines have numerous arrangements, ratings and serial-number prefixes. A matching engine family alone does not guarantee injector interchangeability. Always confirm the injector number against the engine serial number, arrangement number and original injector before ordering.
