• 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.

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.

Time Spent Repairing:

15-30 minutes

Tools Used:

Screwdriver

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.
