2. Reassembly of the power supply unit
(1) Mounting the rotor ass'y
Before inserting the Rotor <66> into the Housing <59>, mount the Rotor <66> on the Gear Cover
[128]{118}.
NOTE: Without the Gear Cover [128]{118}, the Rotor <66> will be strongly attracted and fixed to
the Stator Sensor PCB Set <58> by its own magnetic force. Be careful not get your hand
caught between the Rotor <66> and the Stator Sensor PCB Set <58>.
Insert the Gear Cover [128]{118} into the Housing <59> in proper direction. Press-fit the Gear Cover
[128]{118} into the Housing <59> as far as it will go by using an appropriate jig, so that the spigot joint
section of the Gear Cover [128]{118} can be pushed evenly.
(2) Wiring of the controller set
(a) Pass the red, white, and black terminals of the Stator Sensor PCB Set <58> through the center
window of the Controller Ass'y <67>, and then connect the terminals with those of the same color on
the Controller Ass'y <67>.
NOTE: Insert each terminal into the mating terminal securely until it contacts the innermost
end.
(b) Pass the 5-wire connector of the Stator Sensor PCB Set <58> through the center window of the
Controller Ass'y <67>, and then connect it to the connector of the Controller Ass'y <67>.
NOTE: Do not reverse the connector orientation.
(c) Connect the 8-wire connector of the Panel Ass'y <72> to the connector of the Controller Ass'y <67>.
NOTE: Do not reverse the connector orientation.
(3) Wiring of the filter PCB set (See the figure on page 14.)
(a) Pass the two terminal-equipped internal wires of the Controller Ass'y <67> through the lower window
of the Back Cover <92>, and then connect the two terminal-equipped internal wires to those of the
Filter PCB Ass'y <78>.
NOTE: Connect the terminal-equipped internal wires to those of the same terminal colors.
Insert each terminal into the mating terminal securely until it contacts the innermost
end.
(b) Connect the two core-exposed internal wires of the Filter PCB Ass'y <78> to Pillar Terminal (A)
<86>.
(4) Wiring of the switch (See the figure on page 14.)
Pass one core-exposed internal wire of the Controller Ass'y <67> through the window of the Back Cover
<92>, and then connect it to the terminal No. 2 or 3 of the Switch <84>.
NOTE: The internal wires are connectable with either terminal.
(5) Wiring of the cord (See the figure on page 14.)
Connect the core-exposed internal wires of the Cord <90> to Pillar Terminal (A) <86>.
NOTE: The internal wires are connectable with either terminal.
(6) Mounting the back cover
(a) Attach the Dust Seal <62> to the Tail Cover <63> and mount it to the Housing <59>. Then fix it with
the Bolts M5 x 14 <61>.
(b) Insert the two shafts on top of the Housing <59> into the two holes on the Controller Ass'y <67>,
then insert the two shafts on top of the Housing <59> into the two holes of the Panel Ass'y <72>.
(c) Mount the Back Cover <92> without getting the internal wires caught and fix it to the Housing <59>
with four Bolts M5 x 16 <93>. Then fix it to the Crank Case [121]{111} with two Bolts M5 x 14 <61>.
