INSTALLATION
Installation is the reverse order of removal.

Install alternator, and check tension of belt. Refer to EM-13, "Tension Adjustment" (QR engine models) or
EM-140, "
Tension Adjustment" (YD engine models) in EM section.
CAUTION:
Be sure to tighten “B” terminal mounting nut carefully.

1. Set rotor to the vise.
CAUTION:

Be careful not to damage the rotor.

Use copper plate or thick cloth for rotor in the vise.
2. Remove pulley cap, using suitable tool.
3. Remove alternator pulley, using alternator pulley adaptor [SST].
INSPECTION
Rotor Check
1. Resistance test

Not within the specified values... Replace rotor.
2. Insulator test

Continuity exists... Replace rotor.
3. Check slip ring for wear.

Not within the specified values... Replace rotor.
Brush Check
1. Check smooth movement of brush.

Not smooth... Check brush holder and clean.
2. Check brush for wear.

Replace brush if it is worn down to the limit line.
