(2)
Tap end plate (7) with soft-faced mallet to break bond with stator assembly (24).
CAUTION
Stator assembly wiring is connected to stationary switch which is attached to end plate.
To prevent damage to wiring, make sure stationary switch is disconnected before
removing end plate.
(3)
Carefully separate end plate (7) from stator assembly (24).
NOTE
