Perkins original Perkins 320-0655 Common Rail Diesel Fuel Injector Assembly for C6.6 C4.2 C6.4 Excavator 10R-7674 2645A751 new injector original new injector

The Perkins Fuel Injector GP 320-0655 is engineered as a direct OEM replacement for the Perkins C6 Series common rail diesel injection system. Designed to match the original equipment manufacturing standards, this injector delivers precise fuel metering and consistent high-pressure injection performance across demanding industrial and heavy-duty applications. It is fully compatible with Perkins C6.4, C6.6, 1106D, 1106D-E66TA, and 1106D-E70TA engines found in excavators, wheel loaders, generator sets, and various industrial power units.

Constructed from premium alloy steel with hardened steel components, the injector features precision-ground needle valves and a precision nozzle designed for superior fuel atomization. The leak-free sealing design and corrosion-resistant construction ensure long service life under high-temperature operating conditions. Each unit is factory calibrated to provide stable engine performance, improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions, contributing to increased engine power output and reliable operation in construction, mining, agricultural, marine, and power generation environments.

Installation of the 320-0655 injector is straightforward as a direct replacement component, with a recommended installation torque of 40-45 Nm. To maintain optimal injector performance and engine reliability, operators should use clean diesel fuel, replace fuel filters at regular intervals, avoid contaminated fuel sources, and conduct periodic injector testing. Proper fuel pressure maintenance, correct ECM coding verification, and adherence to fuel cleanliness standards are essential for ensuring long-term durability and consistent fuel system operation.
