Fuel injector AK 17/112000 Perkins, aftermarket

Fuel injector AK 17/112000 is an aftermarket part for the Perkins-engined JCB machines. According to the product card, the injector is for Perkins AK-series engines.

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. Keep the injector well and connections clean. The code on the injector body must stay legible.

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