SOURCE: proform treadmill belt won't stay centered.

Adjust the tension on the right side rear using an allen wrench. Try 1/4 turn clockwise( should tighten). then run tread mill for 30 sec. to see if it centers itself. repeat again if not. if its to tight then turn the left side in a 1/4 turn

SOURCE: broken belt on treadmill

Sorry for bad news but there is no possible way to fix the belt once they come apart.It is best and safer to buy a new belt,there are many websites that sell treadmill belts if you do not have access to parts locally

SOURCE: i have a horizon t92 treadmill. my problem is with

Loosen rear tension and recent and tighten.

First grab the walking belt on an edge and lift up, It should only lift up 3 inches, this about the right tension

There are two guides underneath near the front make sure the belt is underneath them. (they touch the white side)

If OKay, remove the endcap byu the tension control bolts (two screws underneath) and make sure you have adjustment room (threads showing on bolts toward the rear)
these bolts should look about the same position with respect to the roller.

Run the machine on slow, walk on it and try to stop the walking belt, if it slips - turn both rear bolts 1 turn clockwise.,repeat until it doesn't slip

Get off and run the machine on slow 2mph, turn the bolt on the side the belt wanders to 1/4 turn clockwise. If it goes over fast you may need turn the bolt 1 full turn right away (it shouldn't). If its kinda of stable - speed up machine to 5-6 and repeat.

Note the front of the belt should be centered first, this is preset and usually doesn't need adjustment

SOURCE: the belt on my treadmill is off to one side. how

Here are two solutions one is to get the belt centered on the treadmill and the other is to tighten the belt.

There should be two bolts in the rear of the treadmill, one on each side. These bolts adjust the rear roller of the treadmill. The walking belt will always go to the side that is looser. To get the belt back on track, (if you can start the treadmill so the belt is running) tighten the bolt on the side that the belt has slipped to. Tighten the bolt a little bit at a time. If you tighten the bolt too much, then the belt will go to the other side.

To tighten the belt, start by locating the two bolts that adjust the rear roller (one on each side of the unit in the back). Run the unit at about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that what you do to one side, you MUST do to the other side or the belt will get off center. After you tighten it 1/4 turn, check the belt to see if it is still slipping. If it is then tighten the belt 1/4 turn again. Continue until the belt does not slip, but do not tighten the bolts more than 2 full turns.

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.

I bought a new belt for my golds gym trainer 420. I took the belt off the front roller fit snug. I try 2 put the roller back in place, but the side with the motor belt will not sit correctly in place.


Most treadmills have two screws at the back of the treadmill that adjusts tension on the belt. If the belt is staying on the left side of the treadmill pad then adjusting the left ***** out should make it go back towards the center.

I have a life fitness next generation treadmill and the belt has slipped all the way over to the right hand side and is unusuable. How can I fix?


Belt adjustments are on the back of the machine on either side on the rails. Loosen both off first to slide belt over towards center. Then tighten slightly. Run treadmill on lowest speed and adjust from side to side until belt stays centered. After it seems to stay centered run treadmill on high to see if it stays centered and make small adjustment until it does

Belt on treadmill is moving towards the right and bunching up


you need to adjust the travel of belt. to do this you need a allen wrench that came with it. if you have it run treadmill at slow speed,go to the rear right at the right end cap there is a hole, use the allen wrench and unscrew slowly while watching the belt until returns to the middle. if it slips when walking go back to rear and adjust by screwing in one turn on each side until belt wont slip.

On my Sears ProForm 730 treadmill, I cannot make the belt move to the right (it is rubbing on the left side) by turning the left-side back belt screw clockwise (in any amount). The belt is walking back...


The belt does not need to be replaced more than likely. The problem is probably because that adjustment bolt is stripped out causing it loosen and keeping it over on that side. ProForm sells star washers that help them stay steady and not slip out. I would call them and ask for a couple of star washers and a new adjustment bolt for that left side.

I have a Proform 380 Treadmill. When the treadmill is on the belt rubs on the left side.How do I center the belt?


If the walking belt is off-center, first remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the allen wrench to turn the left rear roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the bolt counterclockwise 1/2 of a turn. 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 centered.

Walking belt on image 10.0 tread mill slips, purchased it used, can see where it has rubbed to the left. How to adjust it?


There are adjustment screws on the very back of the deck… one on each side.

1. You will need a hex wrench that came with your unit (look on the side of the deck) sometimes it is attached to a bracket or look in your plastic bag with your instruction manual. If you cannot find it, do not worry, it is a common “hex” size. Purchase a "multi size” hex wrench at the hardware store"

2. Locate the screws on the back of the treadmill on the deck "where you walk" You will see one on each side.

3. With your wrench in hand, start your treadmill on a low speed and take note of which side the belt is "creeping" to the left or right.

4. If the belt is not centered and over to the left side take your tool and adjust the screw on the left side slowly a few turns until you notice the belt creeping back to the center....usually it does not take much adjustment.

5. Once you start getting the hang of what adjusting each particular screw does to the belt....You will be a pro in no time.

6. Once the belt centered, turn off the treadmill and unplug it. Take your hand and slide it under the belt about midway. The belt should feel "snug" against the deck. If it feels too loose...use your new found adjusting skills to tighten the belt adjusting each side a few turns…unplug…checking for tightness until you feel good about it.

7. Last suggestion: Some treadmills decks need lube to help it run smooth. Without it your deck will get worn and the belt will "stick" to the deck....not good. Buy the lube a sporting goods store or at a place that sells treadmills. If you cannot find any buy some spray on graphite.

Everything seems to work fine except a small slip in the track about every 30 seconds or so. Is there something that needs to be tightened?


The walking belt may be too loose. If you have made recent adjustments, lubricated, or had repairs, a belt can slip if not tightened. The belt can slip if you have too much friction or if the belt has been recently lubricated. If lube does not help your problem and you have exhausted all other possibilities, the walking belt is most likely worn out and must be replaced.
To adjust the belt: Less Belt Tension: turn both adjustment bolts on back of treadmill in a counter-clockwise direction. More Belt Tension: Turn both adjustment bolts equally in a clockwise direction. Center Adjustment (moves belt center to the left): Turn left-side adjustment bolt counter-clockwise. Center Adjustment (moves belt center to the right): Turn the left-side adjustment bolt clockwise.
An over tightened walking belt can raise the amp draw of your treadmill, contribute to seam separation on the walking belt, or both, so do not over tighten the walking belt.
You should be able to lift the belt in the center on the side by approximately 2” to 3”, if you cannot lift it by 2” to 3”, the belt is too tight.
