Description:
This CB430) Makita carbon brush set contains two individual carbon brushes. The set contains genuine Makita replacement parts, and comes packaged in a Makita retail box.
This brush set will fit the Makita tools listed below.

• 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.

Drill was no longer reliable and worked only intermitently
I removed the old worn out brushes which was the hardest part of the repair. They would not come out of the copper lined holes, almost as though they had expanded. They seemed to catch on tabs folded down into the brush wells. I pulled one of the wires out of the carbon brush while trying to remove it so I had to completely disassemble the drill. Once I did that the removal of the brush was accomplished but there were a lot of parts that needed to be aligned to get the drill back together correctly. Bearing cups and notches for alignment and trigger and direction change contact points etc. Lots of places that could have gone wrong but I got it together again carefully (don't force anything) when it is right the drill body parts close easily and fully and can be screwed together again. Then the brushes (new) dropped right in. I screwed the brush covers back in place and the drill now works perfectly and has its original power back and works all the time.

The speed control trigger switch on my cordless drill only worked intermittently. And when it did work, the drill would only run full speed. I suspected the trigger switch but did not rule out the mo
The two halves of the drill body were held together with approx. eight identical screws. Removing the screws allowed the halves to come apart revealing the interior parts. Following the wiring colors, I disconnected wires from the switch and reconnected them in the same place in the new switch. The new switch fit into place perfectly. I then replaced the brushes by removing the old and putting in the new. Getting the two halves back together proved a bit tricky but with patience and a couple tries it all went back together OK. Replace screws and done! Drill works like new and I saved $150 dollars.

2) Remove old brushes.
3) Insert new brushes.

Question: Makita Cordless Drill Model 6339...

beverly

my drill has to be bumped to make it run. how do I remove the brushes?
WJA
Hello beverly,

To remove the CB430 Carbon Brush Set. Use a flat screwdriver to remove the item number 20, part number 643807-7 Brush holder Cap from the rear of the Makita 6339DWDE 14.4V Cordless Drill. Then remove the CB-430 from the brush holders. You may want to clean out the Brush Holder to make sure there is no debris in the corners. Then replace the Brushes and screw the Brush Caps back on. Don't tighten them to much the are brittle and can break.

Question: Slow Turning 6217D

mtodd101

Hello. I have a 6217D Makita Dril. Battery is a 1234 12v reading 12.9v. When I pull the trigger, the drill very slowly turns and gradually speeds up but never even close to top speed. It comes to a stop when I try to drill a hole even in soft wood. Can you help troubleshoot this for me. Thanks Matt
WJA
Hello Matt,

I would start with the Brushes make sure they are making good contact with the armature. Then take a look at the Armature, inspect it for any burnt wires or uneven or burnt and commutator bars. The last thing I think it could be would be the Switch, it being the most expensive of all three lets hope it is the brush set.

Good luck,
-WJA
Question: Replace Brushes In A6347d Drill

bshores

Hi Bshores,You should be able to remove the brush caps and the brushes should pull out.If you can't remove the cap or remove the brushes after the caps are removed,chances are you have gotten the drill hot enough to melt the brush tube holder.At this point you will need to replace the brushes and brush holder assembly.Hope that helps.Good luck.

  • The right parts!
    Fit perfectly and came in a Makita factory package
    Guest - September 3, 2019 Verified Purchase
    Very easy repair. Part came in factory box, so it is OEM.
    Parts were all in stock, so they arrived quickly. These were some of several parts ordered to fix an overworked tool. All went in perfect, and the tool is like new.

    Worked great
    Arrived fast
    Guest - August 26, 2019 Verified Purchase
    Easy repair brought my Makita drill back to life!
    It was actually harder to get the old brushes out than to install the new ones. The drill worked sporadically at best before the new Brushes were installed and now it is back to like new condition. Well worth the effort and buying the right parts from Ereplacements
