There should be belt tension screws on the back of the walking deck. You can adjust those out to pull the slack from the belt. The machine should have a slight amount slack in the belt, but not as much as you are describing.

It's certainly worth trying to get the belt tensioned up correctly. The machine has some age on it, but I wouldn�t say a belt issue is a death sentence for it. If you run into a situation with a bad belt and walking deck then I would say it's worth looking into a new machine.

If you cannot find the adjustment screws or they will not adjust out any, let me know and we can look for a work around.

Thank you for using Manage My Life!

We tried to find something that tightens the belt, but could not from either top/down or left/right or any angle - the belt is just looped around the platform it rolls on - the model # is PFTL39400 - the Serial # is N12391761.

I have attached a drawing from the owner's manual showing where the adjustment screws are on your treadmill. Give them a shot and let me know what it looks like. Thank you.

Hi again - so we tightened the screws, as per the diagram you provided - however, the 2nd part of the problem still exists - when we turn on the treadmill, the belt slides to the right on the bottom and begins scraping against the plastic, causing the belt to suddenly stop - if you are on the treadmill you can push to the left with your right foot to make the belt go back to center, but this has to be done constantly - what could be causing this? Thx, Syl-

A:

That will be the walking belt causing the issue. If it's been tightened up and aligned (hard not to do when tightening) and it still wants to pull to one side or the other, then it will be that the walking belt is worn out. I will also mention that the walking deck can cause this problem or make the problem worse. Make sure to loosen the belt up and inspect the walking deck for wear marks on uneven-ness.

Okay, great. So can both the walking deck and the walking belt both be replaced? If so, how much will it cost for parts and labor, to ensure it is worth doing, vs buying a new one.

The walking deck (platform) is no longer in production. The walking belt is part number 148009. I do show it as a current part, however I show it as being out of stock currently. With the age of the machine and the walking deck being out of production, you may want to consider looking at a new machine. There are places online that will custom make platforms, I've yet to have one made that fits as it should.
