ABSTRACT:
A bearing retention arrangement is disclosed for rotatably supporting a shaft (27) within a bearing opening (75) defined by a wall portion (35). The bearing retainer (83) is cylindrical and includes a pair of bayonets (89,91), and the bearing opening (75) defines recesses (77,79) Which conform generally to the bayonets. After the shaft (27) is in place, along with the bearing inner race (63) and bearing members (65), the outer race (67) is pressed into the retainer (83). The retainer is then passed through the bearing opening, with the bayonets passing through the recesses, until the bayonets (89,91) are disposed adjacent a forward surface (71) of the wall portion (35). The bearing retainer is then rotated until the bayonets are no longer rotationally aligned with the recesses, and finally, some form of antirotation device (95,99) is installed to prevent rotation of the bearing retainer from its assembled position (FIG. 3).
