ABSTRACT:
A variable displacement axial piston hydraulic unit (11) has a cradle surface (41) and a swashplate (35) with a convex surface (43). A roller bearing assembly (45) includes a bearing cage (49) defining a slot (53). Bearing clocking is accomplished by a link member (55) which is a rigid, unitarily formed member including several portions. A first portion (57) is pivotally mounted relative to the housing (13). A second portion (67) pivots and slides within an elongated slot (65) defined by the swashplate (35). A clocking portion (69) pivots and slides within the slot (53). The clocking arrangement of the present invention is simple and inexpensive, yet performs the clocking function in an extremely accurate manner.
