Description:
Genuine Makita replacement part

Set of 2 Carbon Brushes with wire lead and brush spring attached.

• 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.

Would not run.
Removed old brushes. Apparently they had swollen/enlarged over time and I had to really pull on them with pliers to get them out. Saw is 12 years old but has never been wet.

Installed new brushes. The new ones slipped right in.

Saw runs like new now.

Was using saw and it just quit.
The repair involved removing several Phillips screws to open the case. Two are longer so note where they go. The only minor difficulty involved removing the brush caps as they were really fried on so plan on replacing them. The old brushes were in pieces, the switch tested good but since I had it apart decided to swap it out as well. Put it back together and wow runs like new! The possible diagnosis on the website made the repairs simple and inexpensive.

Overheated/melted brush holders on Makita 18v circular saw
Could not remove brush caps (fused to holder). Removed end motor trim cap, removed half of the handle to expose wiring. Thought I had to take whole motor apart to install new brush holder, but found out that I could remove brush holder just by wiggling wire through motor (had to tape a wire to wires so when I pulled old brush holder through motor, I could reverse process to install new brush holder). Just watch out for any springs in trigger assembly.

Tool Type:
Circular Saw
Parts Used:
Carbon Brush Set - CB441
Holder Cap, BJR182Z - 643829-7
Armature - 510095-0
Repair Difficulty:
Hard
Time Spent Repairing:
More than 2 hours
Tools Used:
Screwdriver, Pliers, Multi tool remove brush caps, other small tools.
Brushes deteriorated and froze -- saw lost power
1. Opened the back of the saw with brushes. Brushes were frozen and melted.
2. Using multi tool and small blade carefully cut open the brush caps and removed them. They were melted into the brush holder.
3. Realized that I would need to destroy the brush holders to get the remains of the brushes out of the unit. So I set the unit aside and ordered a set of brush holders.
4. Opened the saw unit as described in a video. Removed the armature. The armature maybe is ok. Replaced it anyway.
5. Carefully removed the two brush holders making sure I knew the black(negative) side and the red(positive) side. Take a picture if needed so you get the correct brush holder in the correct side of the unit.
6. Insert the new brush holders. Wire them back to where the old ones were attached.
7. Insert the new armature unit.
8. Close up the unit and put the cap back on the brush side of the unit.
9. Insert the new brushes. Pay attention to the curvature to align it with armature correctly. Should only got into holder one way(rectangular in shape).
10. Screw on the brushes cap. Rotate the blade by hand (no battery in unit) and make sure blade turns freely. If not, check your brushes to make sure they are correctly inserted.
11. Put a battery in the unit and try it out.
