1-1-5. Disconnecting Internal Wires and Electrical Parts
(1) Disconnect the internal wires from the switch as follows.
Insert the J-86 pin into the hole for the internal wire of the Switch [25] <24> (24). Press the leaf spring so
that the internal wire can be disconnected, then disconnect the Internal Wires [23] [24] [26] [27] [35] [36],
<31> <32>, (31) (32) and the Internal Wires of the Choke Coil [23] [27] and the Noise Suppressor
[37] <33> (33). (For the internal wire of the Cord [34] <30> (30), loosen and remove the terminal screw of
the Switch [25] <24> (24) with a slotted screwdriver.) If the leaf spring is pressed too much, the leaf
spring may be set permanently and the contact pressure with the internal wire will be reduced. Replace
such switch whose leaf spring has clearance of 0.5 mm or more with new one.

(2) After removing the two Tapping Screws (W/Flange) D4 x 16 [33] <29> (29), the Cord [34] <30> (30) and
the Cord Clip [32] <28> (28) can be removed from the Housing (A) of the Housing (A), (B) Set
[18] <17> (17).
1-2. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to the following items.
1-2-1. Reassembly of the Armature and the Stator
(1) Press fit Ball Bearing 608VVMC2EPS2L [14] <13> (13) and Ball Bearing 626VVMC2ERPS2S
[17] <16> (16) onto the Armature [15] <14> (14). Stop pressing when Ball Bearing 608VVMC2EPS2L
[14] <13> (13) comes in contact with the Fan. With a vernier caliper or similar tool, check that the press-
fit dimension is 123.8
deformation or other damage to the Fan, particular attention is required. Also, if press fitting is
insufficient, it will cause loss of thrust of the Armature [15] <14> (14), resulting in heat generation.
Accordingly, press-fit Ball Bearing 626VVMC2ERPS2S [17] <16> (16) until it butts against the stepped
portion of the shaft.
