Step-by-Step Guide to Replacing Brushes in Dewalt 333 Random Orbital Sander
Replacing the brushes in your Dewalt 333 is a straightforward process, provided you carefully follow these steps. Before beginning, remember to unplug the sander to ensure your safety.
Step 1: Disassemble the Sander
-
Remove the Dust Bag and Sanding Pad: Start by detaching the dust bag and sanding pad. This will give you unimpeded access to the motor casing.
-
Unscrew the Housing: Using a Phillips screwdriver, carefully remove the screws holding the motor housing together. Be sure to place the screws in a safe location so you don’t lose them.
Step 2: Access the Brushes
Once the motor housing is removed, you will be able to see the motor and the carbon brushes.
-
Locate the Brush Holders: The carbon brushes are typically located on opposite sides of the motor. You will see them housed in small holders secured by screws.
-
Remove Brush Holders: Using a flathead screwdriver, carefully pry off the brush holders. Take care not to damage the housing or surrounding components.
Step 3: Remove Old Brushes**
Carefully pull out the worn-out brushes from their slots. Inspect them closely to ensure that you have indeed removed both brushes. If they are stuck due to carbon buildup, you may use a soft brush to clean out the compartment.
Step 4: Install New Brushes
-
Prepare the New Brushes: As you unpack your replacement brushes, check that they are identical to the old ones in size and shape.
-
Insert New Brushes: Gently insert the new brushes into their respective slots, ensuring they sit snugly.
-
Reattach Brush Holders: Secure them back in place using the screws you removed earlier. Ensure they are tightened but be cautious not to overtighten.
Step 5: Reassemble the Sander
-
Reattach the Motor Housing: Carefully replace the motor housing, aligning it with the screw holes.
-
Screw the Housing Back Together: Use the Phillips screwdriver to replace all the screws you had taken out. Make sure they are tight enough to keep the housing secure but again, be cautious not to overtighten.
-
Reattach the Dust Bag and Sanding Pad: Finally, reattach the dust bag and the sanding pad.
Testing Your Sander
Before proceeding with any project, it’s important to test your tool after performing maintenance. To do this:
-
Plug in the Sander: Ensure the sander is plugged into a functioning outlet.
-
Power On the Sander: Turn on the sander and observe its performance. It should operate smoothly without any unusual noises or interruptions.
-
Check the Sanding Functionality: If all goes well, run the sander on a scrap piece of wood to gauge its sanding effectiveness.
The sander should feel powerful and perform just like it did when you first purchased it.
Maintaining Your Dewalt 333 Random Orbital Sander
Now that you’ve successfully replaced the brushes, it’s essential to keep your sander in good condition. Here are some tips on maintenance that can help prolong the life of your tool:
Regular Inspection
Regularly check your sander for signs of wear and tear. Inspect the power cord, motor housing, and sanding pads. Ensure everything is in good working order.
Cleaning the Dust Collection System
A clogged dust bag can affect the performance of your sander. Make it a habit to empty the dust bag frequently, and clean it as necessary.

What are the symptoms of worn-out brushes in my Dewalt 333 Random Orbital Sander?
Worn-out brushes in your Dewalt 333 Random Orbital Sander can manifest through several noticeable symptoms. One of the most common signs is a decrease in performance, where the tool may run erratically, lose power, or produce inconsistent sanding results. Additionally, you may notice that the sander has difficulty starting or may stall during operation, which is typically indicative of brush wear.
Another sign to look out for is visible wear on the brushes themselves. If you disassemble the sander and see that the carbon brushes are worn down to a minimal length, it’s time to replace them. Also, if you notice sparks coming from the motor area during use, it may signal that the brushes are no longer making proper contact with the commutator, leading to inefficient performance.

Replacing the brushes in your Dewalt 333 Random Orbital Sander requires safety precautions and proper tools. Begin by unplugging the sander to ensure there is no electrical current flowing. Next, use a screwdriver to remove the outer casing or cover, exposing the motor and brush holders. Be careful not to damage any components while disassembling. It’s also advisable to wear safety glasses to protect your eyes from any dust or debris.
Once you have access to the brushes, gently pull them out from their holders. Take note of their orientation, as you’ll want to install the new brushes in the same way. Insert the new brushes, ensuring they fit securely into place. After replacing the brushes, reassemble the sander, plug it back in, and test it to ensure everything is functioning properly.
Where can I purchase replacement brushes for the Dewalt 333 Random Orbital Sander?
