Time
30-60 minutes
Tools Used
Screwdriver, Pliers, I used a ratcheting screwdriver with a T15 and T20 tips
I removed the 3 screws in the top of the sander
I brushed all the dust out with an old paint brush
I removed the brush clamp and pulled the wire from the brush and installed the new brush.
Screw the brush clamp back on and attach the wire
Repeat on opposite side
Then I remove the switch I needed a pair of slip joint pliers to remove the wires from the back
Install new switch and attach new switch boot
Put the top of sander back on and screw the screws back in and plug it in and test it out
