Dismounting1) Disconnect negative (–) cable at battery.
2) Remove right side drive shaft referring to “Front Drive Shaft Assembly Removal and Installation in
Section 3A”.
3) Disconnect generator lead wire (“B” terminal wire) and coupler from generator.
4) Remove generator belt. Refer to “Water Pump / Generator Drive Belt Re moval and Installation”.
5) Remove generator bracket bolts and generator pivot bolt.
6) Remove generator. Remounting
Reverse dismounting procedure for remounting noting
the followings.
• Tighten each bolt and nut to specified torque referring
to “Generator Unit Components”.
• Adjust belt tension referring to “Water Pump / Generator Drive Belt Tension Inspection and
Adjustment”.

Generator InspectionS7RS0B1A06008
Rotor
• Using ohmmeter, connect positive terminal to “FR” terminal and connect negative terminal to “B” terminal of generator, check that continuity between “B” terminal and “FR” terminal. If there is no continuity, replace rotor or
regulator.
• Using an ohmmeter (1), check for continuity between slip ring s (2) of rotor. If there is no continuity, replace the rotor.
Standard resistance between slip rings of rotor
: 1.7 – 2.0 Ω

Downloaded from www.Manualslib.com manuals search engine 1J-12 Charging System:
• Using an ohmmeter (1), check that there is no continuity between slip ring (2) and rotor core (3). If there is
continuity, replace the rotor.
• Check slip rings for roughness or scoring. If rough or scored, replace the rotor.
Stator
• Using an ohmmeter (1), check all leads (2) for continuity. If there is no co ntinuity, replace the stator.
• Using an ohmmeter (1), check that there is no continuity between coil leads (2) and stator core (3). If
there is continuity, replace the stator. Brush and Brush Holder
Check each brush (1) for wear by measuring its length
as shown. If brush is found worn down to service limit,
replace brush.
Exposed brush length “a”
Standard: 16 mm (0.63 in.)
: Limit: 5.0 mm (0.20 in.)
Rectifier
Using ohmmeter, check continuity between “B” terminal
(1) or “E” terminal (2) and each diode lead (3).
Check both directions by reversing probes of ohmmeter
and there should be only one-way continuity in each
case. If check result is not satisfactory, replace rectifier
(4).
