Abstract

An apparatus comprising a holding unit configured to hold a fuel injector for disassembly, a removal unit and an actuating unit. The removal unit comprises a first removal tool for removing a circlip and ferrule ring from the fuel injector, a second removal tool for removing a cone nut from the fuel injector, and a third removal tool for removing a screw from the fuel injector. The actuating unit comprises a first actuator configured to operate the holding unit, a second actuator configured to move the removal unit, and a third actuator configured to operate the third removal tool.

Claims (37)

1. An apparatus for disassembling a fuel injector, comprising:

a holding unit configured to hold the fuel injector for disassembly;

a removal unit comprising:

a first removal tool configured to remove a circlip and ferrule ring from the fuel injector;

a second removal tool configured to remove a cone nut from the fuel injector; and

a third removal tool configured to remove a screw from the fuel injector; and an actuating unit comprising:
