4 Pay attention to the mounting direction of the Ring Gear [16] , Slide Ring Gear [23] , Pinion (C) [24] and Pinion (B) [26] (see Fig. 8). Mount the Front Case [11] to the Rear Case [20] so that the concave portion of the Front Case [11] aligns with the protrusion of the Rear Case [20] (see Fig. 15). 6 Fit the protrusion of Washer (B) [29] in the concave portion of the Rear Case [20] and turn it clockwise viewing from the armature until it contacts the Rear Case [20] (see Fig. 12).

If it is too hard to mount, support the Motor Spacer [30] and press down the rear end of the armature shaft of the Armature and Pinion Set [31] with a hand press. (b) Mounting the Magnet [32] Mount the Magnet [32] to the Armature and Pinion Set [31] so that the notch of the Magnet [32] faces the rear of the Armature and Pinion Set [31] . Hold each part securely as the Armature and Pinion Set [31] may be attracted to the Magnet [32] by the strong magnetic force (see Fig. 13). NOTE: Be careful that the ball bearing and the washer at the rear of the Armature and Pinion Set [31] may come off due to the magnetic force of the Magnet [32] .
