Remove the Stator
Ensure the engine/alternator assembly is set on a sturdy
work surface. Do not set the engine/alternator assembly on
the plastic end cover.
1. Remove the plastic end cover ( A , Figure 12).
2. Remove the two mounting screws that secure the
brush holder ( C ) to the rear bearing carrier. Disconnect
the brush holder and set aside.
3. Remove the four stator bolts ( L ) that secure the rear
bearing carrier to the alternator.
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 (
H ).
5. Slide 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 ( D ) that secure the alternator
adapter to the engine adapter ( J ).
2. Loosen, but do not remove, the rotor through-bolt
( B ). The rotor through-bolt will prevent the rotor from
falling during disassembly.
3. While supporting and pulling the rotor with one hand,
strike the rotor assembly, on the steel laminations
with a plastic, dead blow hammer (Figure 13) until it
separates from the engine shaft.
Assemble the Alternator
1. Install the rotor and torque to values listed in
Specifications.
2. With stator harness and lead wires facing away from
the engine, place stator ( A , Figure 14) over rotor and
into adapter casting ( B ). Verify roll pin slot ( C ), in
stator, lines up with the roll pin ( D ) in adapter.
3. Use a plastic, dead blow hammer to evenly seat stator
into the adapter casting.
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 from the engine.
