Description:

This brush set will fit the Makita tools listed at the bottom of the page.

• 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.

Maintence

Using a flat head screwdriver, remove the brush caps, then remove the old brushes. You may want to blow out the brush holders and clean the edges of them so the brushes will slide easily. Then install the new brushes and replace the brush caps.

Carbon brushes had worn out. I have had this Makita for 15 years. I was easy to install by taking the screws on one side out, take the two screws for the brushes out and install the new ones.

Time Spent Repairing:

30-60 minutes

Tools Used:

Screwdriver

The motor speed varied when the control switch was at high.

Took out the old bushes with a flat screwdriver turning back the covers and replaced with new. The unit performed better but it was not a complete fix. The next step for me would have been to replace the armature so I disassembled the unit with a Phillips screwdriver. Everything looked fine other than a few carbon marks as the old bushes had worn down. I buffed with 320 wet/dry paper and reassembled with the new bushes. Unit is back to 100 percent.

Great service

The parts I purchased from eraplacementparts brought my makita beltsander back to life. This was my favorite beltsander and has been a discontinued model for several years now. It's great to have a source for hard to find parts. I'm a woodworker and always have power tool that need repair. I'll definitely be back. Thank you for your help and speedy service.
