Perkins original Common Rail Fuel Injector for C9 330D 336D E330D E336D E340D Construction Machinery Parts original new injector

The Perkins C7 fuel injector is engineered for heavy-duty diesel applications requiring precise fuel metering and long-term reliability. Manufactured to OEM-level dimensional standards, this HEUI injector features hardened alloy steel internal components produced through precision grinding, ensuring consistent atomization, accurate injection timing, and reduced fuel consumption across all engine load conditions. It is designed to operate with ultra-low sulfur diesel and complies with global fuel standards, making it suitable for international deployment in construction, mining, power generation, marine, and industrial sectors.

Compatible with Perkins C7, C7 ACERT, C7.1, industrial, marine, and generator engine variants, this injector cross-references 20R-8064, 10R-7222, 10R-7221, 20R-8968, 20R-1917, 229-1775, 235-3907, 254-4339, 267-3360, 293-4072, 328-2574, 387-9433, 557-7633, 553-2592, and 572-0119. Its corrosion-resistant construction and high-temperature tolerance support stable operation in demanding environments such as mining trucks, drilling equipment, standby generators, commercial vessels, and pump drives. The expected operational lifespan may exceed 10,000 hours under proper maintenance.

Installation requires cleaning the injector bore, fitting new copper washers and O-rings, lubricating seals, tightening to specification, and performing electronic ECM calibration to verify injection parameters. To maximize service life, operators should use high-quality diesel, replace fuel filters regularly, prevent water contamination, avoid extended idle periods, and follow OEM-approved cleaning procedures.
