January 20, 2016
Fixing things makes sense. This article will help you make sense of replacing the motor brushes and holders (brush boxes) on a DeWALT cordless hammer drill.
Replacing the carbon brushes on a DeWalt cordless drill The Facts

Motor brushes worn out? It's time to face the fix. Whether you are a master carpenter or an occasional drill-seeker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

The motor inside your DeWALT cordless drill has two separate carbon brush assemblies: one on each side of the motor. The brushes transfer electricity to the motor's spinning armature. Because they're made of carbon, motor brushes will eventually wear down, and will need to be replaced.

Common signs that your motor brush assemblies need to be replaced are excessive sparks coming from the brush area of the motor. Also, if you pull the trigger on your drill, but the motor doesn't turn on, the brush assemblies are likely in need of replacement.

This article provides step-by-step instructions for removing and installing the carbon motor brush assemblies on a DeWALT cordless hammer drill.
