Caterpillar original 245-8272 Diesel Fuel Injector 192-2817 for Machinery Diesel Engine 3512C, replacement for OEM 246-1854, 0R-3539 Common Rail Engine Injector original new injector

For operators of Caterpillar 3500 Series heavy-duty diesel engines, sourcing a specification-compliant fuel injector is critical to avoiding unplanned downtime across demanding industrial worksites. The CAT 245-8272 is a brand-new diesel fuel injector built to match original Caterpillar OEM specifications, acting as the final fuel delivery component in the diesel injection system. It is compatible with 3500 Series variants including 3512B, 3512C, 3516B, 3516C and 3508 engines across industrial, marine and generator configurations.

Engineered for continuous harsh-environment operation, the 245-8272 features CNC-machined injector bodies for dimensional accuracy, hardened alloy steel internal parts for wear resistance, and specialized coatings against moisture and sulfur corrosion. Its consistent fuel metering and precision atomization deliver improved fuel economy, cleaner combustion, better throttle response, higher horsepower, lower emissions and extended engine life, with a high-temperature rating for extreme engine bay conditions.

This versatile injector suits power generation, marine propulsion, mining, oil and gas, construction, industrial pumping, railway and emergency backup power use cases, covering equipment from haul trucks and cargo vessels to data center generators and drilling rigs. It comes with a 12-month warranty and cross-references to 125-8272 (alternative) and 10R-1272 (reman) to streamline industrial parts sourcing.
