Product Description

?

Set of 2 Carbon Brushes with wire leads and brush springs attached. The set contains genuine Makita replacement parts, and comes packaged in a Makita retail box. This brush set will fit the Makita tools listed at the bottom of the page. • Worn brushes frequently are the cause behind a motor running poorly. • Replacing brushes can fix a motor that's operating intermittently. • New brushes can restore a motor's electric braking. Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.

Replaced the brushes, the switch and the power cord. Fixed. Ohmed out the power cord after the repair was completed and figured out that the power cord was bad. So, all it needed was a power cord but by then the other parts had also been replaced anyway. Success overall, so that is what counts.

Replaced the brushes, easy enough since they had two screws holding on dust covers. BUT, after both were replaced, motor still didn\'t run. I opened another access panel and saw that a wire lug was bent over and was touching the motor armature. The lug was melted, but once I crimped on a new one, it fit tightly onto the receptacle which I had bent and was no longer touching the armature. This time the motor ran fine. Since the brushes weren\'t very worn, I believe somehow the lug got bent over, shorted to the armature and overheated the brush spring. I got the hammer from a friend that said it didn\'t work and if I wanted it I could have it. NICE, it works great!
