Black dust, something rubbing, Stripped front roller? Treadmill c 2000 nordic track bogging down
Treadmill has new belt, but still “bogging down” while running/walking on it. When inspecting belt and front roller, I noticed a lot of black powder coming off something. Now I believe it’s from roller? Roller itself is black, but the end part where belt attaches, the shiny metal is visible. I need to know why it is happening?? There’s nothing rubbing at that spot, but clearly, black covering is off there to a bare metal.
