Replaced belt, tension pulley, rear rollers, glide pads and felt pads. Nothing was particularly difficult with the repair or installation of the parts. There is not much space to install the new tension pulley, because the nut is underneath the motor and hard to see/reach. I solved this by putting the nut in a box end wrench and putting a small piece of duct tape over it so it wouldn't fall out while the bolt was starting to thread into the nut. Others had mentioned having to remove the motor to get the pulley on, but this is a free and easy fix. Everything else was very straightforward. You will also need some snap ring pliers with very small posts to grab the clips on the rollers.
