Dewalt genuine replacement part, that is sold individually. 2 are needed for the tools listed below. It is always best to replace both brushes, even if only one is worn. 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.

Simple but necessary part
New part needed for my older electric mower. A few bucks spent on this save me hundreds on buying a new mower.
Pretty easy to install as long as you hold the spring of the brush housing tight.

Black And Decker LM170, Removed plastic cover, all torx head screws but was able to use flat head. Entire top of electric lawn mower removed can access brushes, could see the worn brush, one side completely gone and spring no longer keeping tension, pushing brush against armature of motor, poor contact would spark intermittently.

... Read moretorx that keeps brush assembly in place and then removed worn brush from spring loaded assy. Crimped new brush wire to where the old one connected and re install brush assy, cover and you are ready to mow!!! It took me a total of 20 minutes, but can probably replace a brush on this electric mower in 5-10 minutes next time, very easy, do not pay someone to fix this!!!

Lawn mower stopped working altogether - as if the motor had burned out. I discovered that the carbon brushes were worn to the point of not making good contact with the commutator.
I removed the old brushes and rectifier, then installed the replacement rectifier using a silicone grease. I connected the new brushes using a crimping tool and new wire crimps, then re-assembled the mower. With $30 worth of repair parts, the mower has since been working like new, which saved us from having to buy a new mower.
1. Removed cowling of motor with Torx wrenches
2. Removed brush assemblies with same, one by one so that I would have a model as to how to put them back together.
3. Cut wire to brush, discarded old brushes
4. Stripped the cut wires, connected to new brushes
5. Put all the parts back
Had to cut wires to power cord before removing motor, dissembled motor found bearing and magnets broken, armature and brushes was ok, but still replaced brushes, ordered new parts, they were promptly delivered, cleaned up parts replaced motor housing with new magnets and new bearing, also replaced worn out, bent blade, now works like new

Mower would not start. It would run if I held down the switch and turned the blade by hand. I used a wooden stick not my hand though.
Replaced the brushes and cleaned the motor commutator. I also dressed it with some emery paper to present a smoother surface for the new brushes. Put it back together and it works like a charm. Glad getting the parts was so easy. The illustrations are very good and helpful too.
Removed holder for old brushes and replaced with new, had to clip the wire on the old brush and had to solder wires together - old brush had a split ring to fasten wires together was not able to remove from old wire so cut off and trimmed the insulation from old wires and soldered brush wire.
1. Remove the cover of the lawn mower.
2. Remove the old brush holders.
3. Cut the brush wires.
4. Carefully install the terminals in the brass brush holder with the spring behind it.
5. Reconnect the wires (be careful as the terminals are small and the spring will go flying out)
