Change bearing of Align 600L brushless

Mine is over 300 flights and the motor bearing is still fine and I decided not to change it. The bell is nicely balanced . The rear bearing is notched and grainy.

Procedure:

1) mount the 600L on a motor mount. Place the mount on a clamp.

2) Use a DIY tool, or a rotory saw blade driver with teeth 29mm apart. This can turn open the base cap. The base cap has loctite with the stator base.

3)Use a bearing clamp to remove the stator from the base cap. Or you can punch the stator out with the base cap supported.

4)The front bearing, magnet bell can then be removed. There should be a copper washer, of same size as the Trex 450 main gear washer.

5) This is the most difficult part. To remove the rear bearing, one has to punch from the other side of the stator. Align put lots of loctite on the rear bearing. You need a hex socket (size6/8 inch?) to bear the stator base. I use a 5mm Trex450 main shaft with a 6mm copper tube. Thing is easier if you get a 6mm shaft to punch out the rear bearing. Remember another copper washer is underneath the rear bearing.
