However, over time, the belt on your treadmill may start to wear out or become damaged, making it difficult or unsafe to use. 



  • Fortunately, replacing a treadmill belt is a fairly simple process that you can do yourself with the right tools and instructions.


In this article, we'll provide step-by-step instructions for how to replace a treadmill belt.


Step 1: Gather the Necessary Tools


  • You'll need to gather a few tools that will be necessary for the job.

  •  You'll need a screwdriver (either a Phillips or a flathead, depending on the screws on your treadmill), a wrench, a lubricant spray (such as silicone lubricant), a tape measure, and a replacement belt that matches the size and specifications of your current treadmill belt.


Step 2: Unplug the Treadmill


  • The first step in replacing your treadmill belt is to unplug the machine from the wall outlet. This is an important safety precaution that will prevent any electrical shocks or accidents from occurring during the process.


Step 3: Remove the Motor Cover


  • You'll need to remove the motor cover to access the treadmill belt. This is typically done by unscrewing a few screws on the side or bottom of the machine. Use your screwdriver to remove the screws and carefully lift the cover off the motor.


Step 4: Loosen the Tension Roller


  • The tension roller is responsible for keeping the treadmill belt tight and in place while in use. 

  • To remove the old belt, you'll need to loosen the tension roller by using your wrench to turn the bolt that holds it in place. 

  • Keep turning the bolt until the tension on the belt is completely released.


Step 5: Remove the Old Belt


  • With the tension released, you can now remove the old belt from the treadmill. Simply lift it off the machine and set it aside.


Step 6: Measure the New Belt


  • Before installing the new belt, you'll need to measure it to ensure that it's the correct size and length for your treadmill. 

  • Use your tape measure to measure the length and width of the new belt, and compare these measurements to those of the old belt to ensure a proper fit.


Step 7: Install the New Belt


  • With the new belt properly measured, it's time to install it onto the treadmill. Begin by aligning the belt on the deck of the treadmill and making sure that it's centered and straight. 

  • Then, loop the belt around the front and back rollers of the machine, making sure that it's sitting evenly and tightly in place.


Step 8: Tighten the Tension Roller


  • With the new belt in place, it's time to tighten the tension roller. Use your wrench to turn the bolt in the opposite direction that you used earlier, slowly increasing the tension on the belt until it's tight and secure. 

  • Be careful not to over-tighten the roller, as this can cause damage to the belt or other parts of the machine.


Step 9: Lubricate the Belt


  • To ensure that your new treadmill belt runs smoothly and lasts as long as possible, it's important to lubricate it regularly. 

  • Use your lubricant spray to apply a thin layer of lubricant to the underside of the belt, as well as to the rollers and deck of the treadmill.


Step 10: Replace the Motor Cover


  • With the new belt installed and lubricated, it's time to replace the motor cover. Simply align the cover with the motor and screw it back into place using your screwdriver.


Step 11: Test the Treadmill


  • Finally, plug the treadmill back into the wall outlet and turn it on to test the new belt.

Let's set the record straight : we're not actually doctors, much as our mom would love to brag otherwise. We're two brothers from Olive Branch, MS, who have an MBA, an MDiv, and a Master's in Political Science between us-but no MD.

Over the years though, we've certainly earned our specialties in "elliptretics" and "treadmllology" - and Clark really did start out by using a stethoscope to diagnose faults with treadmills ( hence the company name).

In fact, we've been in this industry since Clark was still In school in 1987 - when the commercial fitness equipment Industry was only a few years old. And It's no longer just us two: today we're a team of 32 fitness- equipment enthusiasts, - all devoting our lives to keeping your machines in peak condition.
