Carbon Brush 2610005646

On my Dremel 4000, it started running sporadically even without a load; speeding up, slowing down, loss of power, etc
So, I used a screwdriver to remove the caps that cover the springs and brushes on both sides. I then removed the old springs and brushes, and used a q tip and some rubbing alcohol to clean inside the cavity. I then installed the new set of springs and brushes, paying attention to the curvature of the end of the brush so that it matched the surface that it will be in contact with. Then I replaced the caps compressing the spring as I screwed the cap down flush with the surface of the Dremel body. Then I ran the tool at top speed for 5-8 minutes without a load to allow the new brushes to properly seat themselves. Now it runs like new again. Success! For under $10, not bad

1. Removed old springs and brushes.
2. Replaced with new parts.
3. Simple replacement of parts and the tool ran like new!

I took off the Dremel outer cover. You remove the brushes, and the hanger wire, remove the screws and carefully split the Dremel in half at the division line. The blue guide lever power on off can be pulled out of where it firmly sits. You can see prior to taking it out if it rubs/ pushes the power button and listen for the click which is the telling sign. You can press it with your finger and hear how it should sound/engage click. You pull out the guide lever and slide the new one in place exactly as before, and put it back together. One of the brushes was chipped on the corner, so I replaced them to be sure that wouldn't be a secondary cause..

I popped off the brush screws, places in the new brushes. Reassembled the casing but it wouldn't work so I had to take the Dremel apart and found a disconnected wire. Reattached it an now it works like a charm.

A simple repair. I opened the Dremel multi tool up to see what was causing the problem. The detailed pictures and parts list made ordering the correct parts easy. I was just planning to purchase the armature but after reading a few comments, I realized I would also need the brush and springs. After receiving the parts, I removed 5 screws, pulled out the old armature and slid the new one in. Reassembled the tool and slid the brush and springs in on either side. Done and fully functional!

Replaced motor brushes.

Removed the brush caps and replaced the new brush. The repair video was helpful. Thanks!

Replaced old brushes along with
Specifically
1. Remove power cord from wall
2. Unscrewed the two flathead screws securing the brushes inside
3. Pulled brushes from each side
4. Removed the 5 or 6 T15 TORX screws
5. Removed collar on drive shaft and hanging bracket from the rear
6. Took top off and notated which wires went where.
7. Removed the two brush holders and replaced with new ones
8. Reassembled and tested

The repair was pretty straight forward except the spring did not fit the 4000 model as stated. The brushes were exactly the same size so I just took a chance and carefully pulled the spring off of the old brushes and pressed them on the new ones.
