Like in the video, it's best to remove the adjustment screw, so it doesn't get in the way. Then, using a screwdriver, you should be able to pop each leg of the nylon roller housing out. If your existing roller is worn out, note that it doesn't matter in what condition it is when you remove it, since you won't need it anymore. Just use some force and pry it out. |
