Introduction

This guide will assist you on how to replace a Dewalt DCF885 Brush. The brush assembly is used to conduct electricity to the armature as they rotate in one direction from brush to brush. This will allow the motor to turn depending on the armature.

The brushes may wear out over time thus requiring a replacement which can be referred to using this guide and the tools down below. Before beginning, use a knife to cut the middle of the sticker located at the base of the handle for ease when disassembling the part.

  1. D4mLSkWysGyj2GHT

    • Press the battery release button at the top of the battery.

  2. X2RPQDIawpY2QTa3

    • Pull the battery away from the tool.

  3. HRd5lhECTLEpJDie

    • Remove the eight 18 mm Torx Security #10 screws.

    The area circled in red in the center of the three circles in a row going left to right above the trigger in the picture above is not a screw, it is just a square open area. The 8th screw is hidden by the persons hand in the picture, it is located just to the left of their thumb.

Can you tell me the exact model number of the unit in this tutorial? And/Or the part number for that switch assembly? I cannot find that specific switch assembly anywhere! Thank you.
