There was a broke belt and a bad bearing on my Porter Cable Random orbit sander and the feet and pad for my Ryobi sander were wore out.
1. On the Porter Cable sander I had to remove the bottom housing and the flywheel.
2. I decided after finding so much dust inside the housing to completely disassemble and blow out and clean the inside of the motor.
3. I had to press the bearing out of the flywheel and press the new one in using a bench arbor press.
4. Reassemble the housing and test sander it work like new.
5. On the Ryobi I had to remove the housing to remove the foot for each side.
6. I used compressed air to clean the motor.
7. I inserted the new feet and reassembled the housing.
8. I peeled the pad and cleaned the residue off with mineral spirits.
9. I carefully place the new pad in position and made sure it was properly aligned and that the pad adhered to the base plate.
10. Tested sander and it worked like a new sander.

Hook and loop pad was worn out, and the sander wasn't collecting dust.
1. Removed the old pad (3 screws)
2. Put the Random Orbit belt in place
3. Placed new pad on and replaced the three screws
4. Turned sander on - worked like a charm!
What was most helpful was your diagnostic suggestions on the web page. I would not have known about the need for the new belt without that.

Easy Repair
The shipping cost more than the part. Company provides good schematics so you know what you need and any issues involved (there were none).

I received a belt for a Porter Cable Random Orbital Sander
Getting parts from eReplacement Parts is quicker, better, and less expensive than ordering from Amazon, and the same price you would pay Porter Cable if you would order from them. When I need repair parts for tools or equipment I always go to eReplacement Parts for quick delivery, a reasonable price and information if required. Definitely a great source for repair parts.
