Caterpillar original 162-8813 Common Rail Fuel Injector for C3500B Engine Replacement for OEM 229-1631, Application for C3500 Equipment, Cross Reference 246-1854, 250-1302 original new injector

For procurement teams, maintenance engineers and heavy equipment operators managing CAT 3500 Series assets, the Caterpillar 162-8813 diesel fuel injector assembly is a precision-engineered fuel system component purpose-built for the CAT 3512B V12 turbocharged diesel engine platform. Manufactured to meet strict OEM specifications, it delivers accurately metered, finely atomized fuel at precisely controlled timing to support stable combustion, consistent power output, reliable cold-start performance, emissions compliance and optimized fuel efficiency under demanding operating conditions.

Its precision-machined internal components and industrial-grade alloy construction meet OEM-equivalent quality standards, and are engineered to withstand the high pressures, extreme temperatures and corrosive environments common in continuous-duty industrial operations. Superior fuel atomization enhances combustion efficiency to reduce both excess fuel consumption and exhaust emissions, while wear-resistant materials extend the injector’s operational service life to lower long-term maintenance and operating costs.

This injector is compatible with a broad range of 3512B-powered equipment across core industrial sectors, covering all verified applicable categories from diesel generator sets and marine propulsion systems to mining power units, drilling equipment and pipeline pumping systems. It supports fast, accurate part matching via verified cross-reference numbers 8N7910, 8N7911 and 8N7920, making it a reliable replacement solution for power generation, oil and gas, marine, mining, construction and manufacturing operations.
