(Fig. 4)
(1) Use a wooden or plastic hammer to gently
tap on the end surface of the Housing
Ass'y [16], in order to loosen and remove
the Armature [47].
(2) Use a bearing puller to extract the Pinion

and then remove Washer (A) [45] and the
Woodruff Key 2.5 x 8 [46].
(3) Finally, use the bearing puller to extract
the Ball Bearing 608VVC2PS2L [9], and
then remove the Dust Seal [8].
Reassembly can be conducted by reversing the disassembly procedures. However, special attention
should be given to the following items.
(1) Ensure that the Rubber Ring [44] is properly inserted into the bearing chamber of the Gear Cover [41].
During reassembly, be very careful not to damage the Rubber Ring [44].
(2) When only replacing the Ball Bearing 629VVC2PS2L [43] and Ball Bearing 608VVC2PS2L [9], be very
careful to ensure that Washer (A) [45] and the Dust Seal [8] are reassembled in the proper direction, as
shown in Fig. 5.
