3. Remove the rotor cap nut. Pull the rotor assembly straight down to

remove it from the main body.

To avoid damaging the o-ring inside the seal nut, turn the rotor gear

counterclockwise while pulling downward gently.

4. Remove the main bearing from the main body and replace it with a new

one.

Do not touch the new bearings with your bare hands. Oils from your

skin can damage it.
