Disassembly

1. After removing the three through bolts, insert a screwdriver between the front bracket and stator.

While prying it, remove the front bracket and rotor.

NOTE: If the screwdriver is inserted too deep, the stator coil might be damaged.

2. Hold the rotor in a vise and remove the pulley nut. Then remove the pulley, fan, spacer and seal. Next,

remove the rotor from the front bracket and remove the seal.

3. Unsolder the rectifier from the stator coil lead wires and remove the stator assembly.

NOTE: Make sure that the solder is removed quickly (in less than five seconds). If a diode is heated to

more than 150

C (310

F), it might be damaged.

4. Remove the condenser from terminal "B".

5. Unsolder the plates "B" and "L" from the

rectifier assembly.

6. Remove the mounting screw and "B" terminal

bolt and remove the electronic voltage regulator

and brush holder. The regulator and brush holder

cannot be separated.

7. Remove the rectifier assembly.

8 Brush and brush spring. When only a brush or

brush spring is to be replaced, it can be replaced

without removing the stator, etc. With the brush

holder assembly raised as shown, unsolder the

pig-tail of the brush.

NOTE: If the terminals "L" and "B" of the rectifier assembly are bent, damage might result to the

rectifier molding. Therefore, the plates "B"and "L" should be gently bent at the center.

Alternative method for disassembling the stator winding, brush holder/regulator unit and the

integrated circuit/diode rectifier assembly from the rear bracket. Once the front bracket and rotor

assembly are separated from the rear half of the alternator:

1. Insert a flat-bladed screwdriver between the stator

core and the edge of the rear bracket on the same

side as the brush-holder. Raise this side of the

stator core away from the bracket so as to open a

gap of about 1/2 inch. BE CAREFUL NOT TO

ALLOW THE SCREWDRIVER BLADE TO

ENTER FAR ENOUGH TO TOUCH THE

STATOR WINDING.

2. Maintaining the 1/2 inch gap, insert the

screwdriver between the stator core and the bracket

on the rectifier side and move the stator laterally

towards the brush-holder for a distance of 1/2 to

3/4 of an inch without lifting it from the bracket.
