Replace the Pad on a Random Orbital Sander

Replacing the pad on a random orbital sander is among the most common maintenance procedures found in the power tool market.

Luckily for woodworkers and tool users, it is also among the simplest tasks that your power tools will each of you to perform.

In fact, replacing your sander’s backer pad requires little longer than, well, eliminating one, installing the other, and slapping a couple of screws around in between.

To cut right to the chase, the first step in almost any repair or maintenance procedure would be to disengage and unplug your sander.

All power tools and working machines should be entirely off before you begin working on them.

Furthermore, since not all sanding pads are the same (the consistency of the pads and number of the dust-collection and screw holes vary from pad to pad), the very first step in replacing this item in your sander is making sure that you have the ideal backer pad (from the right producer) for the procedure at hand.

To do so, all you need is the model number of your instrument and among the following couple things: access to the tool’s schematic and parts list, access to a tools/parts/service rep at your favorite instrument parts trader, or access to the internet.

Any of these avenues will set you on the ideal path to finding the exact part number for the precise pad you need.

Share your tool’s model number, and the item you need for it should follow suit.

Once you have procured the right pad for your specific sander, you can get into the meat of this process.

First, eliminate all mounting screws from the present backer pad (there ought to be either three or four screw-holes, another hole (either five or eight) would be for dust collection).

Put the new backer pad on the sander matching the screw-holes in the pad to people on the sander. Insert and marginally tighten-down each screw.

Again, leave each screw slightly loose until all screws are inserted and half-tightened. After all mounting screws are in place, tighten them securely.


Some folks find it easier to fit the mounting screws to the screw-holes on the pad before fitting them to the holes on the sander.

This allows the screws to guide themselves into place. Employing this process, it is still important to half-tighten each screw before completely tightening any of them.

And in that, you’ve substituted the backer pad in your random orbital sander.

Engage the power saw, giver the sander a fast spin to make sure the pad stays put, and think about the thing now in fine fighting form.
