About as simple as it gets. Great price on OEM Part.
My sander backing plate was worn through and shredding belts. Looked elsewhere for a replacement, but they lacked the cork heat sink on the back side. So glad I found eReplacementParts. They have the OEM parts I need to repair my equipment and keep things in working order. I share your sight with friends and family, and will be ordering more parts for other damaged tools soon. Keep up the good work!

Backer pad was worn out and shredding belts
Michael - May 23, 2019
Tool Type
Sander
Difficulty
Easy
Time
Less than 15 minutes
Tools Used
Screwdriver
Parts Used
1. Remove two short screws from leading edge of plate with a Torx 20 screwdriver or bit. Be careful not to lose the lock washers.
2. My new sander plate had a big inventory sticker on it. That label must be removed before installation. Take your time and try not to shred it. Use PB Blaster or WD40 or similar lubricating agent to remove all adhesive from the plate. Avoid getting the lube on the cork side. Wipe it clean after the adhesive is removed.
3. Install the new plate with original two screws. Hand tighten. Don't use a power driver or you risk stripping the aluminum base. (If screws loosen during use, put a drop of medium strength thread locker on the threads and reinstall.)
4. Put on a new sanding belt and you're back in business.

1. Removed the sanding belt
2. Removed the two torx screws holding the old pad to the sander
3. Installed the new backing pad with the torx screws just removed
4. Re-installed the sanding belt and went back to using the belt sander
It was an easy fix and resolved the issue with the sanding belts tearing due to getting caught on the worn out backing pad.

The backing pad had worn down on the center rear and began tearing up the belts.

Release lever cracked, backing pad wore down, idle arm support was damaged

Tools Used
Socket set, Torx
Removed the worn parts. Had trouble removing the cam-arm and cam from the Idle arm support. Lube on the cam helped. It's best to set the cam in place before adding the cam-shaft by compressing the release spring. After that, reassembly is straight forward.
