The Perkins 194-5083 fuel injector is a precision-engineered replacement component designed for the Perkins C12 diesel engine platform. Authorized under OE number 194-5083, this injector assembly is fully interchangeable with cross numbers 10R0957, 10R0958, and 0R9350, ensuring direct-fit compatibility across a broad range of Perkins-powered industrial equipment. The injector is specifically calibrated for Perkins C12, C12 ACERT, and C13 early series engines used in excavators, wheel loaders, haul trucks, marine vessels, and diesel generator sets.

Manufactured under strict dimensional tolerance control, the 194-5083 injector delivers high-precision fuel atomization through advanced nozzle geometry, producing ultra-fine fuel droplets that promote complete combustion and optimized fuel economy. Premium alloy steel construction combined with specialized surface treatment provides superior wear resistance and corrosion protection against sulfur-containing fuels and harsh operating environments. Each unit meets OEM-level manufacturing accuracy standards, supporting emission control compliance and consistent engine performance in heavy-duty continuous operation.

Routine maintenance of the 194-5083 injector includes fuel filter replacement every 250–500 operating hours, injector inspection and fuel system cleaning every 2,000–3,000 hours, and injector testing every 4,000 hours. Diagnostic procedures such as fuel pressure test, injector balance test, return flow test, electrical resistance test, ECM diagnostic scan, and cylinder cut-out test are recommended to ensure sustained injection performance. The 194-5083 delivers reliable service life for Perkins C12 engine applications in construction, mining, marine, energy, and agricultural sectors.
