(4)
Match mark housings, remove four socket head screws, and carefully separate rear housing with
stator from rotor and front housing.
NOTE
When separating the rear housing from the rotor, the brushes and springs will
pop out. The brushes can be reinserted and retained by a pin (straightened
paper clip, etc.) through the access hole in the back of the alternator housing.
The pin will aid during alternator assembly.
(5)
Tag stator leads. Then remove nuts from heat sink tie points (6 places) and carefully separate stator
from rear housing. Reinstall nuts on tie points to retain diode leads (Figure 5-43).
(6)
If necessary, remove nuts and washers securing brush holder. Remove brush holder.
(7)
If necessary, separate rotor and front housing.
(8)
If necessary, remove nuts, tie bar, washers, and insulators from positive terminals.
(9)
If necessary, replace bearings. Refer to paragraph 5.29.b.
(10) If necessary, replace diodes and capacitors. Refer to paragraph 5.30.a.
c. Inspection.
(1)
Inspect all components for damage and wear.
(2)
Inspect alternator drive coupling (part of alternator) for damage and wear.
(3)
Inspect brushes in brush holder for discoloration and wear.
(4)
Inspect stator and rotor for discoloration and damage.
(5)
Inspect bearings for wear.
d. Testing.
(1)
Test diodes as follows:
(a)
Disconnect diode assembly leads, then using multimeter set for ohms, connect one lead to
disconnected diode leads and other lead to heat sink. Note ohms indication on multimeter.
NOTE
Ensure test point on external (negative) heat sink is bare metal.
(b)
Reverse multimeter leads and note ohms indication on multimeter.
