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.

A tool for removing an injector sleeve from the cylinder head of a diesel engine between the rocker arms while the head remains mounted to the engine block within the vehicle. The devices includes a tap having a longitudinal body and a threaded cutting head at one end. A drive member comprises a bolt having a head at one distal 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.

An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member operably associated with the first component and a second member operably associated with the second component. The second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess.

A replacement tool removes an old bushing or installs a new bushing in a driveshaft yoke. A fixture has a guide chamber facing a bushing bore and a first threaded passage. A traveler mounted in the fixture has a plunger received in the guide chamber and a socket that holds the bushing. The plunger has a second threaded passage aligned with the first passage and having a smaller diameter. A set screw can lock the bushing into the socket. A removal bolt with a shaft matching the second passage is inserted through both passages. Turning of the removal bolt retracts the traveler and extracts the bushing. The tool is reconfigured with an installation bolt in the first passage only. A push plug is placed in the guide chamber to transfer force from the installation bolt to the plunger during turning of the installation bolt to press fit a new bushing.
