I have a Ridgid 14" BS14002 on which the tension assembly broke. I ordered a replacement no problem. The piece the broke was the arm that holds the shaft for the wheel. I was able to put the new tension assembly on the saw with no problem. What I can't do now is to get the M12 nut off the old assembly shaft. I thought I'd just order a new nut from the ridgidparts where I got the tension assembly from, but it's been discontinued. So I went to Fastenal and they ordered one for me. Well neither the left hand or right hand thread nuts will thread on to the new shaft. Does any one have any idea how I could get the old nut off so I can put the wheel back on the saw? I wasn't really planning on replacing this saw any time soon.
