–Some of the following pictures may not show exactly your axle, but the indicated operations are correct anyway. –Collect all epicyclic reduction gear parts: the planetary carrier (3), the thrust washers (5), the needle bearings (6), the planetary gears (7), the triangular plate (8) and the snap rings (9) of every pin. Note: with new planetary gears is advisable to assembly new roller bearings.

–Position the planetary carrier on a workbench. –Insert the thrust washers (5) and the epicyclic gears (7) in the planetary carrier pins. –Insert the needle bearings (6) in the epicyclic gears (7). Note: grease well the needles. –Assemble the triangular plate (8) and the related snap rings (9).
