Description:
This carbon brush is an authentic DeWalt replacement part.
It is sold individually, 2 are needed to make a set
• Worn brushes are frequently the cause of a poorly running motor.
• Replacing brushes can fix an intermittently operating motor.
• New brushes can restore a motor’s electric braking.

Carbon motor brushes are one of the most commonly replaced power tool parts.
The reason is that carbon brushes are wear items, meaning that through friction and use they will gradually wear away and eventually will 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, also check your armature for burns, cracks, or other damage which are indications of a larger motor problem needing attention.

Tool Type:
Electric Drill
Parts Used:
Carbon Brush - 176846-04
Armature and Fan - 176850-00SV
Repair Difficulty:
Medium
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Bearing puller
Commutator bar damaged on armature
Remove screws from handle and separate halves to access trigger mechanism and brush holders. Remove brushes.
Remove case screws and separate case at motor and gearbox joint. Be mindful of shims on ends of gear shafts. They need to stay in place.
The armature will now slide out of the case with a little effort. Rear bearing has a rubber coating that will cause some drag for the first half inch or so.
The old bearings can be removed from the armature and installed on the new part with the proper puller however if your drill is heavily used or you do not have a puller it may be best to install new bearings with the new armature. The nose end bearing may be stuck in the plate that serves as the rear of the gearcase. It is just a snug fit and should come out with a few light taps.
Reassemble in reverse order and enjoy.
