Caterpillar original C3500B Engine 20R-1262 Fuel Injector 437-7547 Common Rail Injectors 392-0226 10R-2826 for Excavator Truck Diesel Car Auto Parts original new injector

Designed for the Caterpillar 3512B engine platform, the 20R-1262 fuel injector assembly is a genuine OEM diesel injection component built to Caterpillar's stringent manufacturing specifications. Cross-referenced with service replacement number 10R-0955, this injector is engineered for direct installation into the cylinder head fuel injection port of CAT 3512B, 3512B HD, 3512B Marine, 3512B Generator, and 3512B Industrial engines. Available in new or remanufactured condition, each unit is produced under ISO certified manufacturing and backed by a 12-month warranty.

Functioning as a precision fuel metering and atomization device, the 20R-1262 receives high-pressure diesel, controls delivery timing through its internal valve, and atomizes fuel into microscopic droplets for optimal mixing with compressed air. The result is improved combustion efficiency, higher power output, lower fuel consumption, reduced exhaust emissions, extended engine life, and better cold start performance. Industrial-grade construction provides precision nozzle design, high pressure resistance, corrosion-resistant materials, heat-treated internals, balanced fuel flow, and a leak-tested structure.

The 20R-1262 injector serves a broad range of heavy-duty sectors worldwide, including generator sets, marine propulsion, mining power units, oil and gas drilling systems, offshore platforms, power generation plants, and industrial compressors. To maintain peak performance, Caterpillar recommends using clean diesel fuel, replacing filters regularly, monitoring exhaust smoke, checking fuel pressure, and performing injector calibration during major service intervals. This makes the 20R-1262 a dependable OEM-specification solution for operators running CAT 3512B-powered equipment in demanding environments.
