Perkins original Perkins 392-0224 Diesel Fuel Injector Replacement for Caterpillar 992G SR4 SR4B SR4BHV Wheel Loader new injector original new injector

The Perkins 3512B fuel injector is identified by authorized part number 3512B and cross-references with 392-0224, 326-1646, 3261646, and 3920224, making it a direct-fit replacement for the original Perkins 3512B V12 diesel engine platform. This component is engineered to deliver consistent and precise fuel metering across variable load conditions, ensuring stable combustion efficiency in demanding power generation, marine propulsion, mining, and heavy industrial operations. Manufactured from high-strength alloy steel and finished with anti-corrosion surface treatment, the injector is built to withstand extreme injection pressures and prolonged service cycles.

Designed as an OEM standard replacement, this fuel injector assembly supports a wide range of applications including diesel generator sets for prime and standby power, offshore platform emergency power systems, marine vessels and tug boats, mining trucks, drilling equipment, industrial compressors, water pump stations, and data center generator systems. Its precision-machined construction and strict adherence to Perkins dimensional and performance specifications ensure proper integration with the cylinder head and full compatibility with the 3512B engine family.

Prior to installation, operators should verify the authorized part number 3512B and cross-reference identifiers 392-0224, 326-1646, 3261646, or 3920224, inspect the injector bore for contamination, and clean the cylinder head seating surface. During installation, old injectors must be removed, fuel passages inspected, seals lubricated, and the unit torqued to Perkins service specifications before bleeding the fuel system and performing a startup inspection. Post-installation checks should include leak verification, exhaust smoke monitoring, idle stability assessment, and confirmation of the proper operating temperature range.
