Abstract

An assembling device for assembling and disassembling a fuel injector in a mounting hole of a cylinder head of an internal combustion engine has a jacket body at least partially surrounding the fuel injector. A contact section, on which both a hold-down force for holding down the fuel injector in the mounting hole and a disassembling force for disassembling the fuel injector can be exerted on the fuel injector, and a collar section protruding from the mounting hole are formed on the jacket body. The collar section has at least one thread, in which a disassembling screw can be screwed in so that when the disassembling screw is tightened it abuts on the cylinder head and transmits a disassembling force on the collar section so that the assembling device (1) with the fuel injector (3) inserted into the assembling device (1) is extracted.
