Abstract
An outboard planetary final drive unit for a tractor or truck has a pre-loading arrangement for pre-loading the bearings of the final drive unit. The final drive unit includes a sprocket or wheel on a drive shaft supported by bearings in a support housing. Means for pre-loading the bearings in the form of a plurality of pins of specified length are provided which extend through bores in and on opposite sides of a reaction hub of a planetary sprocket drive where a retaining ring for the reaction hub abuts and bears against the plurality of pins which act to pre-load the bearings.
