Perkins original  495-0327 / 10R-0781 / 222-5966 Common Rail Diesel Injector for 3126 Series Industrial Construction Machinery original new injector

The Perkins 495-0327 diesel fuel injector is a precision-engineered OE replacement component designed for Perkins 3116, 3126, 3126B, 3126E, 3304, and 3306 inline diesel engine series. Built to meet original Perkins OEM quality standards, this injector carries the authorized OE number 495-0327 and is fully interchangeable with cross reference numbers 0R-495, 0R495, 9S-495, 9S495, and 4950327, ensuring straightforward identification and fitment for distributors, fleet operators, and service technicians sourcing replacement parts across global markets.

Manufactured with a precision machined nozzle, hardened internal components, and corrosion-resistant materials, the 495-0327 injector operates within a high-pressure injection environment to deliver consistent fuel atomization and accurate metering. Its OEM dimensional accuracy allows direct installation without modification, while the heavy-duty internal construction supports long service life, reliable cold starting, improved fuel economy, and reduced exhaust emissions under demanding industrial duty cycles.

The Perkins 495-0327 injector is engineered for global equipment compatibility across excavators, wheel loaders, backhoe loaders, motor graders, bulldozers, compactors, heavy-duty trucks, dump trucks, marine vessels, and generator sets used in construction, mining, agriculture, power generation, and oil and gas operations. To maintain optimal performance and injector longevity, operators should use clean diesel fuel, replace fuel filters regularly, avoid water contamination, maintain specified fuel pressure, and perform scheduled injector testing to detect early signs of white smoke, black smoke, blue smoke, fuel leakage, poor acceleration, increased fuel consumption, difficult cold start, or power loss.
