ABSTRACT:
A tool is provided for the safe, efficient installation and removal of clutch assemblies and other engine components on heavy trucks or other machines. A mounting bracket is bolted to the flywheel housing to hold the tool in place and provide support for lifting. Mounting brackets in different sizes may be used for flywheel housings of different sizes. A clutch assembly may then be placed over a removable splined clutch shaft in the correct size for that clutch assembly. An input shaft may be slid manually back and forth through a position rail to provide horizontal motion for moving the clutch assembly toward or away from the flywheel housing. A slack adjuster provides precise rotational movement about the axis of the input shaft for raising or lowering the clutch assembly to the correct height. A lift extender provides additional motion for moving the clutch assembly into or out of position.
