ABSTRACT:
The clutch plate and the housing (including the cover and a diaphragm spring in the cover) of a friction clutch are centered relative to each other and are held at a selected axial distance from each other on first and second centering portions of a mounting tool which has a handle at one end and the other end of which is insertable into an axial recess of the output element of an engine. The cover is centered on and is fastened to a flywheel of the output element before the tool is extracted from the output element, thereupon the clutch plate and ultimately from the housing. The tool is provided with a movable holding portion which maintains the tips of prongs forming part of the diaphragm spring in abutment with a locating portion of the tool to thus maintian the tips in a selected axial position. The holding portion can be disengaged from and can be moved through the splined hub of the clutch plate in response to angular and/or other movement relative to at least one of the centering portions.
