I have replaced the rollers, gliders, and a new belt. When I put the machine back together it seems like it is off centered and has a hard thump on every rotation. When I had the machine apart, I was looking at the idler pulley and it was only solid about half way around. Half of the pulley belt surface area is close to outside diameter of the pulley. The other half drops down inside the pulley close to the center. Is this normal? Should I buy another idler pulley?
ANSWER Hello Adam,
The idler pulley has to be round. Imagine if a tire on your car were shaped like this. You couldn't get a smooth ride because it would not spin true. The same applies to the round, spinning parts inside the unit. Any deviation from true will cause vibrations and noises during operation. I strongly recommend to replace the idler pulley 37001287.
