Clamper 163107-4

Removed 5 screws from base: 4 in the corners and one in the middle (under a flap in the base). The 4 corner screws also hold on the clampers. I had some difficulty removing the base because I didn't realize how tight it was on. After removing the base and the bad clamper I pushed on the new base and clampers and screwed everything back down.

First I found the center phillips head screw on the bottom of the sander and
removed it.
Second, I removed all of the phillips head screws that held the feet and the sand paper
clampers in place.
Third, I slowly took the sanding pad away from the sander, exposing the phillips head screws that hold the feet on and I removed those.
Forth, I let the broken feet and rusted sand paper clampers fall out while paying attention to how they were put in.
Fifth, I put each foot onto where it belonged and screwed in the old phillips head screws at the top of the feet. I then added the new clampers loosely under the new feet and began holding everything together in one hand.
Sixth, this sander has a floating element above the sanding pad, a bearing and a big washer to make it vibrate for the sanding, that I had to also put back into place before screwing in the center phillips screw hand but not tightening it.
Seventh, I started installing the old screws to the bottom of the new feet through the sanding pad, this holds the clampers in place too, careful not to tighten anything till I had all the screws in place. Note: I did this repair on a Workshop brand 7.2volt sander using Makita parts.
