16. Check for continuity between the slip rings (A).
• If there is continuity, go to step 17.
• If there is no continuity, replace the rotor
assembly.
17. Check for continuity between each slip ring (A) and
the rotor (B) and the rotor shaft (C).
• If there is no continuity, replace the rear housing
assembly, go to step 18.
• If there is continuity, replace the rotor assembly.
18. If you removed the pulley, put the rotor in the drive-
end housing, then tighten its locknut to 111 N·m
(11.3 kgf·m, 81.7 lbf·ft).
19. Remove any grease or oil from the slip rings.
20. Push the brushes (A) in, then insert a pin or drill bit
(B) (about 1.8 mm (0.77 in.) diameter) to hold them
there.
21. Heat the rear bearing seat with a 1,000 W hair drier
for about 5 minutes (129
140 °F, 50
60 °C).
22. Put the rear housing assembly (A) and drive-end
housing/rotor assembly (B) together, tighten the
four through bolts (C), and pull out the pin (D).
23. After assembling the alternator, turn the pulley by
hand to make sure the rotor rotates smoothly and
without noise.
24. Install the alternator and drive belt (see page 4-46).

NOTE: Refer to the Exploded View as needed during
this procedure.
1. Test the alternator and regulator before you
remove them (see page 4-39).
2. Remove the alternator (see page 4-46).
3. If the front bearing needs replacing, remove the
pulley locknut with a 10 mm wrench (A) and a
22 mm wrench (B). If necessary, use an impact
wrench.
4. Remove the harness bracket (A), the insulator (B),
the three flange nuts (C) and the screw (D), then
remove the plate terminal (E).
5. Remove the end cover (A) and the dust seal (B).
6. Remove the brush holder (A), the voltage regulator
(B), and the rubber seal (C).

7. Remove the four screws, then remove the rectifier
(A) and the four insulators (B).
8. Remove the four flange nuts, then remove the rear
housing (A) and the washer (B).
9. If you are not replacing the front bearing and/or
rear bearing, go to step 16. Remove the rotor from
the stator drive end housing.
10. Inspect the rotor shaft for scoring, and inspect the
bearing journal surface in the stator housing for
seizure marks.
• If either the rotor or stator housing is damaged,
replace the alternator.
• If both the rotor and the stator housing are OK,
go to step 11.
11. Remove the rear bearing using a puller as shown.
