Abstract
A tool for inserting and fastening a replacement injector sleeve in the cylinder head of a diesel engine. The tool is part of an injector sleeve tool kit which also includes an injector sleeve removal tool. The installation tool includes an expandable mandril which is inserted into the injector sleeve and expands a portion of the sleeve causing a press fit of the sleeve within the cylinder head. The sleeve removal tool includes a tap having a longitudinal body and a threaded cutting head at one end and a bolt having a head at the other end. An extraction nut is threaded onto the threaded shaft of the drive member followed by a bearing surface member such as a spacer. A hollow cylinder or support sleeve having an internal diameter greater than the injector sleeve to be removed and an external diameter less than the diameter of the sleeve bore includes a shoulder member.
