Product Overview
Injection nozzles meter and atomize fuel into the combustion chamber. Hard starting, uneven running, excessive smoke or a cylinder-balance problem can involve nozzle wear, but compression, injection timing and pump delivery should be tested before replacing injectors.
John Deere lists RE48786 as an injection nozzle and application data includes models such as 1450, 6320, 6403 and 6405, plus numerous machines using 4045 engine variants. This listing supplies four nozzles.
Fuel-system cleanliness is critical during installation. Cap open lines, clean the injector bores and use the correct sealing components and torque procedure for the engine.
