Question and Answers


replacing tredmill belt


Replacing the belt on your treadmill is fairly difficult and time consuming. In addition, there are no really detailed instructions for replacing it since that type of service would typically be done by a professional. The basic instructions are listed below to help you.

  1. Unplug the treadmill and remove the motor hood.
  2. Remove the right foot rail.
  3. Remove the rear roller adjusting bolts.
  4. Remove the screws from the right side of the walking board.
  5. Remove the adjusting bolts from the front roller.
  6. Remove the front and rear rollers.
  7. Remove the belt and replace it and the walk board if needed.
  8. Reverse the instructions to reassemble the treadmill.
  9. Use the second image to adjust the walking belt after the new belt is installed.

Again, this is a fairly involved repair, so if you have any concerns or reservations you may want to consult a professional.
