ABSTRACT:
The invention involves a machine, e.g., a walking dragline having a drive gear, a driven member which loads (and wears) gear teeth unequally and an interconnecting shaft. The quill-mounted gear is separately supported by bearings. The shaft can be moved axially and when so repositioned, it is also separately supported by other bearings. When the gear needs to be "indexed," (due to unequal tooth wear) the shaft is moved axially out of connection with the gear but remains connected to the eccentric. The gear can then be indexed using its drive motor and the shaft can be re-engaged with the quill without the necessity of auxiliary lifting equipment and without disengaging the shaft from the eccentric.
