I've got a 15" wide belt sander. Grizzly. Model G9983.
This problem I'm having has been getting progressively worse. A thin strip will tear off of the belt on the left hand edge. The strip that tears off is very even all the way around, it usually remains in the round form, and the rest of the belt is in very good condition. The tearing never happens while we are sanding. It happens just with the sander running, with no stock going through. The feed belt will be a few inches below the sanding belt and the tearing will occur. On one occasion, the tear was not so clean and complete, and the whole belt ended up really getting mangled. The last couple of belts that have torn had not been used much at all.
At first I thought it was maybe the brand of belt and there was a deformity with that brand. But then we recently loaded up a different brand and it shortly occurred again. When you are facing the sander, the tear always occurs on the left edge of the belt.
At one point we were having a problem with the sanding belt tracking too far to the right and pushing against the lever that shut the sander down. So I had to do some adjustments regarding the belt tracking. I did these adjustments following the instructions in the booklet step by step. I did get that problem fixed. Before I did this adjustment, we did have a belt that tore on the left edge, so I don't think my adjustments to the tracking have anything to do with the tearing problem. But the tearing of belts is occurring more and more often, sometimes we've hardly used the belt.
So right now, we are shut down on sanding until we can find out what the problem is and get it resolved.
I am attaching 3 pics of two different belts. The first 2 pics are of the same belt, just different angles of it. The third pic is of a different belt and the piece the tore off of it.
Can anybody offer any assistance on this?
