• Worn brushes are often the cause of a poorly running motor
• Replacing brushes can fix an intermittent motor
• New brushes can restore a motor’s electric braking


Carbon motor brushes are one of the most commonly replaced power tool components.  Because carbon brushes are wear items, meaning that through friction and use they will gradually wear away, they will eventually require replacement.  Worn brushes are common causes of intermittent motor function, reduced electric braking, and reduced motor power.  A worn out brush will often be worn down near the wire lead and may be cracked, pitted, or burned.  When replacing carbon brushes, be sure to also inspect your armature for burns, cracks, or other damage which indicates a larger motor problem.

Hello Steve, Thank you for the question. To remove the brushes you will need to open up the handle and remove the switch. This will give you access to remove the brushes and replace them. Thank you for your inquiry, good luck with this repair!
These bushes are listed for the BO5041K. Will they also work in my modal BO5041? Thank you

Makita palm sander; Took a little figuring to get it apart; had to pry the bearing out of the sanding pad. Need to be sure all the screws are taken out before pulling it apart. Brushes went in fine.

An old sander that had a bad bearing and ruined brushes.
had to take the sander completely apart. The brushes were an easy fix. It was tough to get the old bearing off the shaft and set the new bearing on the shaft. It took some ingenuity and a loy more time than i expected. The bearing was an exact fit. Thank goodness for the right parts. The sander is now ready for the next 40 years.

Dropped sander and broke 3 of 4 feet.
Removed plate and split case. Slid the broken feet out and slid new feet into place. I replaced the brushes since I had split the housing and had easy access to them. Made sure wires were properly routed and retained before re-assembling and blew out sanding dust. Case screws are different lengths but are NOT easily mixed up. Nothing tricky about the repair and parts fit perfectly.

3. Removed the armature and used a small gear puller to remove the bad bearing
4. Pressed the replacement bearing in the shaft using a deep socket and hammer
5. Removed the seals on the remaining bearings and re-packed them with low viscosity grease
6. Replaced worn brushes
7. Reassembled the sander and tested it.
8. Now I have a sander that runs like new.

    these went in perfectly
    what do you say about brushes - I got these with some other parts to fix up my trusty Makita corded ⅜" drill - all the parts, including these brushes, fit perfectly - the whole operation took maybe 15 minutes and the drill works like new - so much better to fix good tools than to throw them away and replace them - I feel like I'll get an other 30 years out of this drill - if I last that long myself - otherwise the kids will insert them along with tools from MY grandfather - and they will all be working.
