I know that it can be very difficult to have issues with your treadmill. I should be able to help you with replacing the drive belt on the treadmill.

  1. Unplug the treadmill.
  2. Loosen the rear roller adjusting bolts.
  3. Remove the motor hood.
  4. Loosen the motor mount bolts.
  5. Remove the front roller bolt from the right side. #Count the number of turns out so that you can put it in the same spot when you put it back together.
  6. Remove the front roller and belt.
  7. To install the belt, put the belt on the roller and reverse the above steps. Make sure to pull the motor so that the drive belt is tight and tighten the mounting bolts.

I hope this helps. If you need further assistance, please reply to this thread. Thank you for using Manage My Life.

Q:

My Proform 400GI treadmill makes a loud high pitch noise at speeds up to 3.1, possible solutions?

A:

Disconnect the power to the treadmill. Remove the front hood over the motor area and remove the drive belt from the motor pulley.

Walk on the belt and try to create the noise. If you can create the noise this way hopefully you can determine what is causing the noise.

If you can't create the noise without the motor, connect the power and start the motor with the drive belt off. If the noise is coming from the motor, you should be able to tell.

If you don't get the noise this way, inspect the drive belt for cracks, stretch marks, etc. The drive belt might be the source of the noise.

Q:

Where are the side rail screws on my treadmill located?

A:

The screws for the side rails may be "hidden". They do show to be on the topside of the machine. By "hidden", I mean they may have screw covers on them.

I would agree that you need to replace the motor drive belt. The wear on that usually is caused just from use and age. It sounds like the belt is just starting to wear out is all. You will want to check the pulley's for any type of alignment issues or wear issues on them. If a rough edge in the belt way has developed, that could cause the belt to wear prematurely.
