Abstract
A differential apparatus is disclosed of the type including pairs of helical differential pinions for transmitting torque from a rotatably driven differential carrier housing to a pair of side gears splined to a pair output shafts, respectively, characterized by the provision of a collapsible and expansible wedge block spacer assembly for maintaining the output shafts in spaced relation and for reacting to axially inwardly directed thrust forces. During assembly of the differential apparatus, the spacer block is introduced, when in a collapsed condition, into the housing via a transverse access opening, to a position between the output shafts, whereupon the wedge block assembly is axially expanded into supporting engagement with the adjacent ends of the output shafts. The housing includes three sections, a pair of end cover sections being arranged on opposite sides of a center section of contoured configuration.
