Abstract
The invention relates to a machine having a driven gear, service access to which is partially obstructed. An aspect of the invention involves an aperture permitting access to the driven gear through a spatial area away from the obstructed region. The driven gear includes a plurality of arc-like segments mounted on a spider for removal individually and the dimensions of at least one segment and the aperture are cooperatively selected to permit a segment to be removed through the aperture to the spatial area. Segments of the driven gear may thereby be removed for service while yet avoiding removal of the driving gear or other substantial disassembly. A method for replacing the driven gear includes forming the aperture, detaching a segment and removing the segment through the aperture to the spatial area.
