Q:

how do you change the walking belt on a proform j4i treadmill model # 831297210

A:

Thank you for your question.

Replacing the belt 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 belt.

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 rail.
  4. Remove the rear roller adjusting bolts.
  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.
  6. Remove the front roller.
  7. Remove the screws from the right side of the walking board. Then lift the walking board and slide the walking belt off the board.
  8. Reverse the instructions to reassemble the treadmill.
  9. 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.
