Was not even sure this part was still available (30 yr. old) sander. Wish I had known how easy and quick it was to get the part-would have done this years ago.

Rubber pad reduced to size (through usage) that allowed paper to incorrectly position during use.

Difficulty
Medium
Time
Less than 15 minutes
Tools Used
Power Drill, Sharp Chisel, sand paper, steel wool
Parts Used
Removed 4 phillips head screws from base, which turned out to be unnecessary. Replacement of rubber pad requires only removal of old pad remnants, cleaning of metal plate with chisel, sandpaper and/or steel wool, aligning new rubber pad, remove paper on new pad to expose adhesive surface, align new rubber pad, (note phillips head screw positions for proper alignment, the screws must show) and place pad on steel plate. Place sander on bench and if available place weight on top of sander to apply pressure for adhesion. Done!

It's a square pad. Remove 4 recessed screws from bottom. Lift off worn part. Install sandpaper hold down clips on new pad. Align new pad/backing plate on sander, tighten 4 screws. Attach sandpaper and get back to work. I replaced it with the felt pad/backing plate assembly, but also ordered the self adhesive sponge rubber pad only to have as a backup replacement.
