Overview
This replacement brush holder assembly provides the complete housing, spring, and carbon brush unit for power drills and other brushed-motor tools. When the brush holder cracks or the internal spring weakens, the carbon brush loses consistent contact with the commutator, causing intermittent power and excessive sparking. Replacing the full assembly ensures reliable brush pressure and proper electrical contact.

Installation notes
Disconnect the tool from power before beginning. Remove the housing screws to access the brush holder assemblies inside the motor housing. Note the wire routing and terminal connections before extracting the old holders. Install the new assemblies, reconnect leads, and verify the brushes move freely in their guides before reassembling the tool.
Common questions
Q: Will the N031214 brush holder assembly fit my DeWalt DCD930, or is it also used on other 18V models?
The N031214 replacement brush holder assembly is specifically matched to the DeWalt DCD930 platform, but fitment can vary by type number and related models. The safest approach is to confirm your drill’s exact model and type from the nameplate and compare it to the compatible models listed before installing.
Q: What are the signs that the brush holder assembly on my DCD930 needs to be replaced?
Common symptoms include intermittent motor operation, excessive sparking at the brushes, reduced power, or a burning smell coming from the motor area. If the brushes are worn unevenly or the holder is heat-damaged, replacing the full N031214 assembly is usually more reliable than trying to reuse the old holder.
Q: Do I need to do anything special when installing the N031214 brush holder assembly in a DeWalt DCD930?
Yes—disconnect the battery first, then open the housing carefully so the brush leads and springs stay in position during removal and installation. It also helps to inspect the armature commutator for heavy scoring or carbon buildup, because installing new brushes against a damaged commutator can shorten brush life and affect performance.
