STARTING AND CHARGING
1. Scratch setting marks between the front and rear
brackets and the alternator body (2 locations).
This will ensure installation to its original position.
2. Remove the 4 through bolts.
3. Use the blade of a screwdriver to pry the front
bracket and the stator apart.
4. Carefully separate the front bracket, pulley, and
rotor from the stator and rear bracket.
NOTE:
• Do not push the screwdriver blade too deeply into
the stator. Coil damage will result.
• A vise may be used to secure the rotor. Be sure to
clamp the vise at points A (see illustration below).
Do not clamp the vise at points B. Damage to the
rotor will result.
5. Remove the 2 screws ( 2 ) attaching the coil
terminal plate to the IC regulator.
6. Hold the coil assembly in your hand. Be careful
not to damage the terminal plate.
7. Remove the 3 screws ( 3 ) and the coil assembly.
8. Disconnect the connector ( 1 ).
NOTE: It is very important that Steps 5, 6 and 7 be
performed in that order. If Step 6 is performed before
Step 5, terminal damage will result.
9. Remove the cap and nut from the rectifier termi-
nal stud.
10. Use a screwdriver to pry the rear bracket and the
side entry terminal apart.
11. Remove the side entry terminal.
NOTE:
The tube will remain in the rear bracket. Take
care not to lose it.
12. Remove the rectifier retaining screw and the 2 IC
regulator retaining screws.
13. Remove the stator and rectifier assembly (as a
single unit) from the rear bracket.
14. Remove the IC regulator.
15. Unsolder the 4 stator coil leads from the rectifier
terminals.
16. Remove the stator from the rectifier.
NOTE: High temperature solder with a melting point
of 230 °C connects the stator coil leads to the rectifier.
Use a 180
~
280 watt soldering iron to free the leads as
quickly as possible. Do not apply the soldering iron for
more than 5 seconds. Diode damage will result.
BEARING REMOVAL
NOTE: Bearings are not normally removed. If they are
removed, they must be replaced with new ones.
Front bracket bearing
Remove the 4 retainer screws. Press out the bearing
with a suitable tool.
Rotor bearing
Use an ordinary bearing puller.
