A casting broke on my belt sander

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.

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.
