The invention describes a device for preloading a bearing (41, 42) for the pinion (101) in the central gear (110) of a vehicle (100). The pinion (101) has gear teeth (2) at its one end and is fastened to the propeller shaft driver (3) at its other end. The pinion (101) is supported by a bearing configuration (4) which is preloaded. A preloading nut (5) on which a collar (8) is provided is used to slide shims into the bearing to achieve correct preloading. When correct preloading is achieved with the preloading nut (5), the propeller shaft driver (3) is situated on the shaft (1) of the pinion (101). The propeller shaft driver (3) has an internal cone at the end which faces towards the bearing configuration (4), and fitting causes the collar (8) of the preloading nut (5) to extend in under the propeller shaft driver (3) and become locked by shape to the shaft (1) of the pinion (101). |
