Front face of ball bearing must be at least 5/32 inch (3.97 mm) below front face of drive end housing. (f) Place ball bearing (23) in position on bearing bore. Place ball bearing tool (fig. F-1) on top of bearing so that larger diameter end is in contact with bearing. Press bearing in until it bottoms out against bearing stop on shaft of rotor (14).
