remove housing 4. Disconnect lead 6 from alternator terminal 61
and undo contact bolt extension 5.
Lock the alternator pulley with a tool from kit 67.7823.9504,
undo the pulley retaining nut and press the pulley out using a
puller.
Remove the pulley key and taper washer.
Tool kit 67.7823.9504 includes an ordinary picker and a grip.
The grip consists of two steel half-rings, inserted into the pulley.
The half-rings are of the same cross-section area as the
alternator drivebelt. At one end they are connected by means of
the joint, at the other end they have levers to be compressed by
hand when removing the pulley.
Disconnect the wire from the alternator terminal «B».
Disconnect the voltage regulator and capacitor leads from alter-
nator terminal 30, undo regulator 1 retaining screws (Fig.7-12)
and withdraw it. In case of pre-1996 alternators to prevent dam-
ages to the brushes when removing the brush holder. Insert a
screwdriver between regulator 2 housing and brush holder, then
partly pull out the regulator from the alternator, leaving the brush
holder in place. Next swing and withdraw the regulator complete
with the brush holder from the alternator. Undo the retaining
screw and remove suppression capacitor 20.
Undo clamp bolt 14 nuts, remove alternator housing 11 and
rotor 8. Undo the bolt nuts, connecting diode ends to stator wind-
ing terminals, withdraw stator 7 from alternator housing 17.
Undo contact bolt 6 nut, disconnect the supplementary diode
wire terminal from connector 3, remove diode plate 5.
Alternator - reassembly
The reassembly of the alternator is the reverse of the dis-
mantling procedure.
In case of pre-1996 alternators (with detachable regulator /
brush holder unit), in order to avoid damage to the brushes,
before refitting the regulator complete with the brush holders, do
not fully insert the brush holder into the regulator, it should be
pushed in place only partly, then insert the assembly as such into
the alternator. After the brush holder is refit into the alternator
housing, press lightly the regulator into the alternator.
Out-of-concentricity for the holes in the alternator housings
must not exceed 0.4 mm. Therefore during reassembly always
insert a special gauge into these holes.
The taper spring washer of the pulley must be assembled
with the convex side facing the nut. Tighten the pulley securing
nut to a torque of 38.4-88 N•Ï (3.9-9.0 kgf•m)
