I have a question about my porter cable 371 compact belt sander, it runs well as it should, but recently, the spring for the tracking knob, is getting weak, I start the sander and use it and the belt goes into the metal edge and destroys the belt every time, what do I need to get the tracking knob off to put on a stiffer spring so it doesn't do that? I tried to twist off the knob, and at the end, it keeps turning without coming off, any ideas? Thx
