• 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.

Question: Part Number Progression For Thes...

toolstore

Makita's original part number for these brushes was 191978-9 then CB-318, then CB-336 and now is CB-340.

Hello toolstore,

Over the last few years Makita has made quite a few part number changes in their brush sets. I know that some of them were basically the same brush set with a different part number. That is one reason for all the part number changes. And manufactures often update part numbers for reasons that I just don't know why.
