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.

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.

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

how do you get the old ones out of the drill
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.
