perfect fit
This item was difficult for me to install but it was exactly like the original piece on the sander. Was very happy to get it back up and running at such a low price. Obscure part but easy to find on this site.

Release lever cracked, backing pad wore down, idle arm support was damaged
Em - December 5, 2016
Tool Type
Sander
Difficulty
Medium
Time
30-60 minutes
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.

A casting broke on my belt sander

Parts Used
I took the tensioning mechanism apart with a torx wrench and a compression pin
remover (difficult without tool). Watch out for the small ball bearing and spring
under the lever. I then reassembled it with little difficult until it came to putting
the pin back in the lever. The compression used broke the lever casting so I
now have to order that. be very careful that your tool supports the bottom
of the lever evenly. Think that's where I went wrong. Don't know, in any event
that's a pretty weak casting.
