Carbon Brush Set

$16.59

Fix Number: FIX10156657
Manufacturer Part Number: CB408

This part includes two carbon brushes with wire leads and brush springs. Worn brushes are typically presented as a failed or underperforming motor. Carbon brushes are a part that commonly wears, so it is a good idea to have these on hand. They are essential for a properly running motor because they conduct electricity to the armature. For this repair, you will start by removing the first brush from the motor, using a screwdriver to remove the brush cap. Once the cap is removed, the brush can be removed. Align the new brush with the holder and then reinstall the cap. Repeat these same steps for the other brush.

Fix Number: FIX10156640
Manufacturer Part Number: CB124

Carbon brushes are needed to conduct electricity to the armature through the commutator. The brushes are continuously rubbing against the rotating commutator, so will wear down over time, and will need to be replaced. If you are experiencing excessive sparks, this can also be caused by a damaged armature, so it is best to check it at the same time. This part includes two carbon brushes, which need to be replaced at the same time.

Fix Number: FIX12522806
Manufacturer Part Number: N031635

This part includes one carbon brush with a wire lead and brush spring attached. A poorly running motor is often due to worn brushes, which is why they are such a common repair in power tools. Due to the constant friction they are under, they will wear over time, and will need to be replaced. If upon inspection you notice the carbon brush is burnt or otherwise damaged, you will also want to check the condition of the armature, as this might suggest a larger problem with the motor.

Carbon Brush With Spring

$15.19

Fix Number: FIX10176277
Manufacturer Part Number: 5140011-85

This is a single carbon brush with a spring. Carbon brushes are what supply electricity to the armature. They are known to wear due to constant rubbing against the commutator, so it should not be a concern if they are in need of a replacement. They should be inspected regularly, especially if your power tool is not functioning properly. A worn brush can cause excessive sparks, however a damaged armature can also cause sparks, so you will need to inspect both parts. This is a simple repair that should only take a few minutes. You will need to remove the brush caps, and then align the new carbon brush in the holder with the tabs. You will need a screwdriver to secure the cap.

Broken belt (motor runs, blade didn't turn)

1) Watched YouTube video before ordering parts to confirm my problem and to get an overview of the repair.
2) found 7-step instruction in user manual - worked perfectly (Part# 901608 (014) downloaded PDF) on page 26
Turned saw over and layed on two 2x8s to protect spindle and it case I dropped the saw. Use a helper if you have one but I did not need one.
3) inspected motor brushes per user manual (had spares ready) 4-step instructions (two brushes) on page 25
4) used stiff brush to clean parts and screw shafts while saw was upside down
5) re-assembled, tested saw, double verified that blade tilt was still at Zero degrees when return to 0 and fense and blade were still parallel.

Cleaning and testing took as long as changing the belt and inspecting brushes. Read more...

Fix Number: FIX10176181
Manufacturer Part Number: 5140010-81

This is a single OEM sprocket for a planer. The feed rollers on a planer are driven by chains and sprockets. The outfeed roller has two sprockets, and the infeed roller has one. When the sprocket wears this can cause the chain to skip. If the tool is consistently being overloaded, the key on the sprocket could also shear. As this part is sold individually, be sure to order the amount needed.

Carbon Brush Set

$16.59

Fix Number: FIX10156641
Manufacturer Part Number: CB154

This is a genuine Makita replacement part that includes two carbon brushes with wire leads attached. Carbon brushes are essential components in power tools and are among the most commonly replaced parts due to regular wear from friction. Over time, worn brushes can cause a motor to run poorly, operate intermittently, or lose electric braking power. Replacing them can often restore your tool’s performance. A worn brush may appear cracked, pitted, burned, or worn down near the wire lead. It’s always best to replace both brushes at the same time, even if only one shows signs of wear. When installing new brushes, be sure to inspect the armature for any damage such as burns or cracks, which could indicate more serious motor issues.
