ABSTRACT:
An improved method and tool kit for removing injector sleeves from the cylinder head of engines includes inserting a pull plate below the upper rim of the injector sleeve. A post projects upwardly from the pull plate and extends from the bore hole in the cylinder head. The upper rim of the injector sleeve is then curled inwardly to relax the injector sleeve in the bore. Additionally, the curled upper rim of the injector sleeve provides a surface against which the pull plate can be pulled to thereby dislodge the injector sleeve from the bore for quick and efficient removal of the injector sleeve.
