Fuel injector 320/06837 JCB 444, OEM

Fuel injector 320/06837 is an OEM part for the machines with the JCB Dieselmax 444 engine.

The biggest factor in injector life is fuel cleanliness: the nozzle holes are a few microns across, and water or dirt in the fuel wears or blocks them. On machines running on poor fuel, the injectors are renewed sooner. When an injector is changed, the sealing washers, O-rings and leak-off seals are always renewed as well. If the engine has run on poor fuel, the fuel filters and water separator are renewed along with the injectors and the bottom of the tank is cleaned, otherwise the new injectors will soon fail for the same reason.

After assembly, bleed the fuel system, run the engine and check for leaks, smooth idle and smoke; on electronic systems, enter the injector code.
