Perkins original Perkins 20R-8061 Fuel Injector for C9 Diesel Engine, Replacement Part for 387-9432 20R-8065 387-9439 new injector original new injector

The Perkins 20R-8061 fuel injector is engineered as a direct OEM replacement for Perkins C9, C9.3, and C9 ACERT diesel engine platforms, carrying full cross-reference compatibility with authorized numbers 287-8061, 10R-8020, 147-2412, and 268-8061. This interchangeability allows distributors, fleet operators, and service workshops to source a single injector part that covers multiple part numbering systems used across global Perkins service channels, reducing inventory complexity and simplifying aftermarket procurement for heavy equipment maintenance programs.

Manufactured to OEM specifications, the 20R-8061 features a precision-ground nozzle, hardened alloy steel body, wear-resistant internal components, and a corrosion-resistant surface finish capable of withstanding high-pressure injection cycles and extreme operating temperatures. The injector integrates into the high-pressure common rail fuel system, where transfer pump pressure is elevated and electronic ECU signals precisely control injection timing. Atomized fuel is delivered into the combustion chamber for efficient mixing with compressed air, resulting in accurate fuel metering, improved fuel economy, stable idle operation, reduced exhaust emissions, and faster engine response across industrial, marine, and generator duty cycles.

Designed for heavy-duty reliability, the Perkins 20R-8061 injector supports long service life, high cycle fatigue resistance, and consistent performance under heavy load conditions encountered in construction machinery, mining equipment, marine propulsion engines, and power generation systems. Compatible equipment models include 330C, 336D, 345D, 349D, 950H, 966H, 972H, 980H, CT660, and CT680. Installation best practices recommend cleaning the injector bore, replacing sealing washers and O-rings, inspecting fuel lines and injector harness, performing leak tests, and verifying injection timing to ensure optimal injector function.
