How to Replace the Motor Brushes on a Makita Planer

Fixing things makes sense. This article will help you make sense of replacing the motor brushes on your Makita planer.

Your power tool's motor uses two carbon brushes to conduct electricity and armature. They do this through the commutator. The carbon brush can wear down over time from rubbing against the rotating commutator and will need to be replaced. Worn brushes can cause excessive sparks around the commutator. Sparks can also be caused by a damaged armature, so you'll want to carefully inspect both if sparks are present.

Let's get started.


REMOVING THE MOTOR BRUSHES   1. Remove the chip guide from the side of the planer.
2. Remove the cap with a screwdriver.
3. Remove the old brush.
4. Remove the brush on the other side.  


  5. Align the new brush with the brush holder.
6. Insert the brush into the brush holder.
7. Secure the brush with the brush cap. (Be careful to not over tighten the brush cap or it will crack.)
8. Repeat this for the second brush.
9. Finish up by reinstalling the chip guide.
