Caterpillar original 162-8809 Fuel Injector for Caterpillar Diesel Engine Replacement for OEM 386-1766 392-0206 for Construction Machinery Excavator Cross Reference 20R-1270 original new injector

The Caterpillar 162-8809 fuel injector is a precision-engineered diesel fuel injection component built to OEM specifications for high-performance CAT diesel engines operating in demanding industrial, marine, mining, oilfield, and power generation environments. As a core high-pressure direct injection system part, it delivers accurate fuel metering and atomization to support optimized combustion, lower fuel consumption, reduced emissions, and reliable operation under continuous heavy-duty loads. It is compatible with Caterpillar 3512B, 3512C, 3516B, 3516C, and selected 3500 Series heavy-duty industrial engines.

Constructed from hardened alloy steel, the injector features OEM-level manufacturing accuracy, high-pressure endurance, and corrosion-resistant construction to deliver stable cylinder performance, improved engine response, reduced carbon buildup, and extended engine service life. Every unit passes 100% flow and leakage testing before shipment to meet OEM precision requirements, and comes with a 12-month warranty for eligible applications. Its industrial-grade design also reduces long-term lifecycle maintenance costs for equipment operators.

This injector fits a broad range of heavy equipment, including diesel generator sets, marine propulsion systems, mining trucks, heavy excavators, oilfield drilling rigs, industrial compressors, and emergency backup power stations. It serves sectors covering power generation, commercial marine, mining, oil and gas, and general industrial manufacturing. Buyers are advised to verify engine serial numbers prior to ordering, and bulk ordering, private label packaging, and technical documentation support are available for B2B customers.
