Step 3 Removing the Main Rotor

To remove the main rotor I used a pair of locking pliers to hold the metal shaft close to the drive gear. Then I slipped a washer (see picture) with a small slot in it between the pliers and the rotor. Now I used a flat end screwdriver between the pliers and the washer to press the rotor off the shaft. You may need to reposition the pliers as the rotor moves to the end of the shaft.
