8-1-5. Disconnecting internal wires and electrical parts
Disconnect the internal wires from the switch as follows.
Insert the J-86 pin into the hole for the internal wire of the Speed Control Switch (2P) [25]. Press the leaf
spring so that the internal wire can be disconnected, then disconnect the Internal Wires [15] [16] [17] [18] [26]
[39], and the Internal Wires of the Choke Coils [26] [39] and the Noise Suppressor [37]. (For the internal wire
of the Cord [36], loosen and remove the terminal screw of the Speed Control Switch (2P) [25] 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.

8-2. Reassembly

Reassembly can be accomplished by following the disassembly procedures in reverse. However, special attention
should be given to the following items.
8-2-1. Reassembly of the armature and the stator
(1) Press-fit the Ball Bearing 608DDC2PS2L [11], Dust Seal [13] and the Ball Bearing 608VVC2PS2L [5] into the
Armature [12]. The Ball Bearing 608DDC2PS2L [11] must be press-fitted until it contacts the fan. At this time,
be careful not to press-fit it forcedly. Otherwise the fan can be deformed or damaged. The Ball Bearing
608VVC2PS2L [5] must be press-fitted until the Dust Seal [13] contacts the stepped portion of the shaft.
