Treadmill belt keeps sliding to the left

Ok i bought I used treadmill from a family member and I see the belt had pulled way to the left..Welli got home ajusted and tighten it up and ran on it for about 30 minutes and right back to the left it was again..I centered it a couple times and after about 30 minutes it pulls back to the left.I removed the cover over the motor and everything looks pretty good besides some belt dust but not a lot..Now there is a screeching sound that sounds like its coming from the top roller and the roller looks like it is kinda wobbly a bit when you close one eye and look real good at the edge of the roller..Also you kinda feel a little viberation sometimes like maybe a bad burn or someting..Any ideal what may be my problem ?? The name on the machine says Pro-form 485 PI

On the side of the treadmill where the tread is running into the foot rail (plastic). go to the rear of the machine and find the hole in the end of the plastic. There will be an allen wrench hole there. Use an allen wrench (should have come with the machine) and tighten this bolt (clockwise) 2 full revolutions. This should move the belt away from the plastic and possibly keep the belt from slipping. Good Luck, Tim

If the walking belt has shifted to the left, Start unit @ 1.0 mph using the hex key, turn the left idler roller bolt clockwise 1/2 of a turn to move belt to the right.

SOURCE: The belt of my treadmill

Hi stewarvm,

you either have a loose belt or possibly a bad bearing.

grab each roller (front and back of treadmill) and try and shake it up and down and front to back to
to make sure the bearings are ok...if they move a lot, then you probably have a bad bearing...if theres no movement, or very litte, they should be ok

now make sure the belts ok by looking at it and determining if one side is looser then the other (the right side should appear or feel looser) then tighten the right adjusting bolt till the belt tracks in the center. the adjuster is at the rear, one on each side of the rear roller.

HERE is a video and instructions of how to track your belt.

its pretty easy to fix and should only take a few minutes to get it right with a little trial an error if you never did it before.

let me know if you need further help.

Hope that helps.

Running mat keeps moving to the left

It looks like you will physically have to inspect the treadmill form under the motor shroud, front roller, frame and to the end where the belt tension bolts are. To see if their anything bent or misalign, this will take some time with good lighting and a extra pair of eyes. You will even have to start the treadmill and watch the entire sequence closely until you see whats happening with traveling running belt. This what I would do Good Luck!!

Belt slipping and moving

Here is a basic procedure that will work for the majority of treadmills out in the market:
If the walking belt has shifted to the left, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn the left rear roller adjustment bolt clockwise, and the right bolt counterclockwise, 1/4 of a turn each. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is centred. b.

My weslo cadence 200 treadmill belt keeps slipping to the left. i keep tightening and loosing it to keep it even but i keeps sliding to the left

please look under the bottom of the treadmill and be sure that your alignment brackets are not benmt/missing. (put the machine in the storage position and look about 2/3 way down the side of the belt) you should see a metal bracket on each side pressing in on the belt. They should be pressing in about 1 1/2 -2 inches to help track the belt.

My treadmill was stored in the vertical storage position for a few months, but now that I want to use it again, I can't figure out how take it down and use it normally. What do I need to do?

Walk up to it. You should be staring at the belt. On the left side there is a knob, you should notice a small metal bar about 3 inches wide holding the actual running portion of the treadmill up. Pull hard on the knob toward your left. This should pull the bar out, then with the other hand let the treadmill running portion down unto the ground.

My belt keeps sliding to the left

The rollers in the front and rear need to be adjusted. If its sliding to the left, than the left side needs to be adjusted out until the belt stops going that way and stays on straight.
