3.Insert both output bearings (6) in the housing, using a round tube of the correct diameter and a hand press.

4.Slide output shaft (4) through both bearings (6) until it rests against top bearing (6).

5.Slide shim (16) over output shaft (4).

6.Press gear (5) onto output shaft (4) and secure with washer (17), castle nut (14), and cotter pin (9).
