4. Remove the stator assembly. You may need to tap
lightly on the stator assembly with a plastic, dead-
blow hammer to loosen it from the alternator
adapter.
5. Side the stator out of the alternator adapter and off
the rotor.
NOTICE: Use care not to damage the windings. Set the stator
on the laminations, not on the coils of the wire.
Remove the Rotor
1. Remove the four screws that secure the alternator
adapter to the engine adapter ( A , Figure 20).
Figure 20
2. Loosen, but do not remove, the rotor through-bolt
( A , Figure 21). The rotor through-bolt will prevent
the rotor from falling during disassembly.
Figure 21
3. While supporting and pulling the rotor with one hand,
strike the rotor assembly, on the steel laminations
(
B ) with a plastic, dead blow hammer until it
separates from the engine shaft.
4. Unscrew the through-bolt and carefully slide rotor off
the engine crankshaft.
Except for certain engine repairs, there is no need to remove
the engine adapter (Figure 22) from the engine.

Reassemble the Alternator
1. Install thr rotor and torque to values listed in Section
4 - Specifications.
2. With stator harness and lead wires facing away from
the engine, place stator ( A , Figure 23) over rotor and
into adapter casting ( B , Figure 24). Verify roll pin slot
( C ), in stator, lines up with the roll pin ( D ) in adapter.
