DISASSEMBLY SERVICE POINTS



<<A>> FRONT BRACKET ASSEMBLY REMOVAL



caution Do not insert the screwdriver tool deep as the stator core could be damaged.
1.With a screwdriver blade inserted between the front bracket and stator core, pry to separate the stator from the front bracket.
2.If they are hard to separate, lightly strike the bracket with a plastic hammer while prying with the screwdriver.

<<B>> PULLEY REMOVAL



caution Use care not to damage the rotor.
With the pulley side facing up, hold the rotor in a vice and remove the pulley.

<<C>> PULLEY REMOVAL



1.Set the special tool to the pulley.
Special tool
    Hexagon socket (MB992281)

2.Set the closed wrench to the hexagonal area of the special tool.
Special tool
    Hexagon socket (MB992281)

3.Insert the hexagonal bit socket having width across flats of 10 mm into the hexagonal area of the rotor shaft.
4.Hold the pulley with the closed wrench. Rotate the rotor shaft clockwise to remove the pulley.

<<D>> FRONT BRACKET REMOVAL



caution Do not insert the screwdriver blades too deep. Doing so could damage the stator coil.
Insert the blades of screwdrivers between the front bracket and stator core, and pry and separate them with the screwdrivers.

<<E>> STATOR / REGULATOR HOLDER REMOVAL



caution
  • Use care that no undue force is exerted to lads of diodes.

  • Check that the heat from the soldering iron is not transmitted to the diode for a long time.
1.Use a soldering iron (180 to 250 W) to unsolder the stator. This work should complete within approximately four seconds to prevent heat from transferring to the diode.
2.When removing the rectifier from the regulator assembly, unsoldered on the rectifier.

<<F>> STATOR / REGULATOR ASSEMBLY REMOVAL



1.Remove 6 installation screws of the stator lead wire, and then remove the stator.
2.Remove 4 installation screws of the regulator to remove the regulator assembly.

REASSEMBLY SERVICE POINTS



>>A<< REGULATOR ASSEMBLY INSTALLATION




After installing the regulator assembly, insert a piece of wire through the hole in the rear bracket while pressing the brush to keep the brush against movement.
note Unless inserting the wire to fix the brush, the rotor installation is difficult.



>>B<< PULLEY INSTALLATION


caution Use care not to damage the rotor.

With the pulley side facing up, hold the rotor in a vice and install the pulley.

>>C<< FRONT BRACKET ASSEMBLY INSTALLATION




After installing the rotor, remove the wire used to secure the brush.

>>D<< PULLEY INSTALLATION


1.Clean the inner race of the front bearing and that of the pulley.


2.Screws the inner race of the pulley until it touches the inner race of the front bearing.

3.Set the special tool to the pulley.
Special tool
    Hexagon socket (MB992281)

4.Set the closed wrench to the hexagonal area of the special tool.
Special tool
    Hexagon socket (MB992281)

5.Insert the hexagonal bit socket having width across flats of 10 mm into the hexagonal area of the rotor shaft.
6.Hold the pulley with the closed wrench.
Rotate the hexagonal bit socket anti-clockwise to tighten it to the specified torque of 97 ± 1 N·m.
