Inspection and Repair
Repair or replace necessary parts if extreme wear or
damage is found during inspection.
Rotor Assembly
1. Check the rotor slip ring surfaces for contamination
and roughness. If rough, polish with #500–600
sandpaper.
066RS014
2. Measure the slip ring diameter, and replace if it
exceeds the limit.
066RS015
3. Check continuity between slip rings, and replace if
there is no continuity.
066RS016
4. Check for continuity between slip ring and rotor core.
In case of continuity, replace the generator assembly.
066RS017
6D3–13
STARTING AND CHARGING SYSTEM (Y22SE 2.2L)
Stator Coil
1. Measure resistance between respective phases.
2. Measure insulation resistance between stator coil
and core with a mega–ohmmeter.
If less than standard, replace the generator
assembly.
066RS018
Brush
Measure the brush length.
If more than limit, replace the brush.
Standard: 5 mm (0.20 in)
066RW009
Rectifier Assembly
Check for continuity across “1” and “2” in the
×
100W
range of multimeter.
066RW011
Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction. In case of
continuity in both directions, replace the rectifier
assembly.
Reassembly
To reassemble, follow the disassembly steps in the
reverse order, noting the following points:
1. Install pulley on the rotor shaft.
Clamp pulley to the vise, and tighten nut to the
specified torque.
Torque: 40 N·m (30 lb ft)
