Why would TC470 belt shred?
I replaced the fan, the belt twice and the jockey wheel. I've checked the bearing which doesn't look oval. But still the belt ends up shredded. I have belt tension, and the machine does basically work.
One clue I have is that the belt rides back and forth over the raised area of the axle, when tumbling forward (mostly), but runs correctly in the "v-groove" area of the axle when tumbling backward(occasionally).
When running forward, it seems to make a "thump" noise about every second which is probably the time taken for a drum rotation. The belt is also running hard up against the edge of the jockey wheel, but returns to the centre when running backward.
Suggestions gratefully received.
