Accurate torque loading of a bearing (28) mounted in a cavity (34) of a housing (30) is achieved by rotation of an adjusting bolt (50). The bearing (28) is retained within the cavity (34) by means of a bearing race (32) that has one element (32a) engaging a positioning ring (40) and a second element (32b) in contact with a loading washer (44). In surface to surface contact with the loading washer (44) is a driver washer (46) that is positionable within the cavity (34) by means of the adjusting bolt (50). The driver washer (46) is in contact with a positioning ring (42) and by an inward adjustment of the driver washer into the cavity (34) the loading washer (44) is forced against the element (32b) to preload a torque on the bearing (28). Once a specified torque level has been achieved, the adjusting bolt (50) is locked in position by the lock nut (56).
