How to Align a Treadmill Walking Belt

 

One of the most commonly reported issues that treadmill owners run into is that of the walking belt gradually slipping off of one side of the track. This may lead to the belt feeling loose under your feet while running or walking. The dislodged belt may also be visibly set off to one side while the treadmill is in motion.

It's important to keep treadmill walking belts properly aligned for a number of reasons. For starters, if a belt becomes poorly aligned, it could actually pose a danger to the person using the treadmill. After all, a belt that's not properly aligned won't have the right amount of tension, which could lead to loosening and make walkers/runners more prone to slipping. Furthermore, if the belt isn't re-aligned, this could also lead to premature wear and tear on the machine itself. Fortunately, aligning a walking belt on a treadmill may be easier than you think; read on to find out how to perform this repair.

For Rear-Roller Adjusting Belts

Many treadmills have belts that can be adjusted using the rear roller, or the one furthest away from the controls of the machine itself. Therefore, it's important to note that this tutorial will focus only on rear-roller adjusting treadmills.

If the Belt Slides to the Right

If the walking belt has begun to slide off to the right side of the roller, use an Allen wrench to either tighten the bolt on the right side of the roller or loosen the bolt on the left side. Be careful, though. When tightening and loosening bolts, less is more. Perform only a quarter-inch turn at a time. Test your work by turning the treadmill on to its lowest possible setting. If the belt seems to be properly aligned, your work is done. If not, you may need to adjust further; just be sure to do so in small increments.

If the Belt Slides to the Left

If you find that the belt slides to the left of the roller while the treadmill is turned on, then you'll need to follow the same instructions above with one exception. Instead of loosening the bolt on the left and tightening the one on the right, you'll need to loosen the one on the right and tighten the one on the left. Maintain the same gradual, quarter-inch turns and check your work carefully.
