Dirty Rollers?
Our Vision Fitness T9200 is ~18 years old but only has 248 miles of walking on it. The running belt started folding in the center and I immediately stopped it. When I got it taken apart, I noticed the rollers were black on the few inches of the ends. The rollers were somewhat dirty and had what looked like fabric stuck to them. I cleaned them with brakekleen to remove the gunk. The black, what looks like paint, remained but does not feel raised above the clean metal surface. It almost looks as if painted. No different than the shiny part. Does anyone have any thoughts? I ordered a new running belt and drive belt. I put a copy of the image of the rollers at https://imgur.com/Q5OjWH8
