How do I replace the walking belt on a treadmill, model #831297363?


Thank you for your question.

Replacing the walking board on your treadmill is fairly difficult and time consuming. In addition, there are no really detailed instructions for replacing it since a professional would typically do that type of service. We do not have a treadmill service manual that shows how to replace the walking board either.

The basic instructions are listed below to help you.

  1. Unplug the treadmill from the power source.
  2. Remove the motor hood on the front of the treadmill.
  3. Remove the right foot rails. The foot rails are screwed to the walking board.
  4. Remove the rear roller adjusting bolts. Be sure to count the number of turns it takes to remove the bolt.
  5. Remove the front roller adjusting bolt. Make sure to count the number of turns it takes to remove the bolt. Then when you reinstall the bolt, you can get it in the same place. If your model does not have a front roller adjusting bolt you will need to remove the bolt that secures the right roller bushing. It helps to incline the treadmill when removing this bolt. Once it is inclined, flex the frame to the left and the bolt should come out enough to release the roller bushing.
  6. Remove the front roller.
  7. Remove the screws from the walking board. Then lift the walking board and slide the walking board and the belt off.
  8. Transfer the brackets to the new board.
  9. Reverse the instructions to reassemble the treadmill.
  10. Before installing the motor hood carefully check the operation. The drive belt might need to be adjusted.

I have added the instructions for adjusting the walking belt below.

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

I hope this is helpful. Please reply below if you need further assistance.
