If you’re considering replacing your treadmill belt, you’re in the right place.
Treadmills are a fantastic tool for maintaining fitness throughout the year. They offer the convenience of logging miles without having to contend with outdoor weather conditions.
Running on a treadmill can also be gentler on your muscles, bones, and joints compared to outdoor surfaces, allowing you to run longer and harder with a reduced risk of overuse injuries. What’s not to love about that?
However, like any machine, treadmills need regular maintenance, and various parts will require replacement over time. The treadmill belt, in particular, bears the brunt of the impact when running. If it begins to wear down, the machine becomes less effective and can even pose a safety risk.
But there’s no need to worry. In this article, I’m going to guide you through a detailed, step-by-step process to replace your treadmill belt easily. Whether you’re a hands-on DIY enthusiast or new to treadmill maintenance, this guide is designed to simplify the process and ensure a smooth, hassle-free experience.

Let’s begin.
The Tools You Need
Before we dive in, let’s talk tools. To successfully replace your treadmill belt, you’ll need a few basic tools.
Here’s what you need to gather:
- A screwdriver (Phillips or flat-head, depending on your treadmill model),
- An Allen wrench or hex key (for adjusting the belt tension),
- A socket wrench to tackle any bolts that stand in your way.
- A marker to mark the points of alignment and ensure a seamless transition.
- Piers
- Cleaning supplies
- A reliable friend to offer both strength and support during the lifting and installation.
Preparing the Treadmill
Before you start replacing your treadmill belt, it’s crucial to prepare the machine properly to ensure a smooth and safe process. Here are the steps to get your treadmill ready for a belt replacement:
- Unplug the Treadmill: Safety first. Make sure the treadmill is completely unplugged from the power source. This step is essential to avoid any risk of electrical shock.
- Clear the Surrounding Area: Ensure you have ample space to work around the treadmill. Move any nearby furniture or objects to create a comfortable workspace, allowing you easy access to all sides of the machine.
- Clean the Treadmill’s Exterior: Give your treadmill a good clean before you start. Wipe down the exterior with a damp cloth to remove any dust or debris. This helps prevent external dirt from entering the machine during the belt replacement.
- Remove the Motor Hood: The motor hood, usually at the front end of the treadmill, protects the motor and front roller. It’s typically secured with screws. Use a screwdriver to remove these screws, and keep them safe for reassembling later.
- Familiarize Yourself with the Belt and Deck: The running belt is the part you walk or run on, and the deck is the surface underneath it that supports the belt. Understanding these components is important for the replacement process.
- Access the Belt Area: Depending on your treadmill model, additional covers or parts might need to be removed for full access to the belt. Refer to your treadmill’s manual for specific instructions tailored to your model.
- Locate the Belt Adjustment Bolts: Usually found at the rear of the treadmill, these bolts are used for adjusting the belt’s tension and are crucial for both removing the old belt and installing the new one.
- Record Initial Belt Tension: If you can, measure the current tension of the belt with a tension gauge or take note of the adjustment bolts’ positions. This will be a useful reference for installing the new belt.
- Organize Your Tools: Arrange all the necessary tools beforehand. Having everything within reach will make the process more efficient and reduce interruptions.
Removing the Old Belt
Great, you’re all set to begin! Now it’s time to remove the old treadmill belt, but remember, this is a delicate process that requires careful attention to ensure everything goes smoothly and safely.
Here’s how to remove the old belt from your treadmill:
- Loosen the Rear Roller Bolts: Use an Allen wrench or hex key and go to the back of the treadmill. Turn the rear roller bolts counterclockwise, but not all the way. You’re aiming to reduce tension, not remove the bolts entirely.
- Ease Tension on the Belt: Once the rear roller bolts are loosened, the belt’s tension will decrease. You should be able to lift the belt slightly off the deck. If it’s still tight, gently twist the bolts a bit more, but avoid making them too loose. Keep the bolts in their slots to prevent the roller from coming out.
- Remove the Front Roller (If Needed): Some treadmill models require removing the front roller to take the belt off. This usually means unscrewing the roller’s mounting bolts with a screwdriver or socket wrench.
- Slide the Belt Off the Rollers: Carefully slide the belt off both the front and rear rollers. You might need to lift or tilt the rollers slightly to help remove the belt.
- Lift the Belt from the Deck: After freeing the belt from the rollers, gently lift it off the deck. Be cautious to avoid snagging or damaging the deck’s surface.
- Clean the Exposed Areas: With the belt removed, it’s a good opportunity to clean the deck and rollers. Clear away any dust, debris, or buildup to ensure smooth operation when the new belt is installed.
- Inspect Rollers and Deck: Before putting on the new belt, check the rollers and deck for any signs of wear or damage. Address any issues to ensure optimal performance of the new belt.
- Prepare for New Belt Installation: Ensure the area is tidy and the rollers are properly positioned for the installation of the new belt.
Here’s How To Put Together The New Belt
Now that the old belt is off, it’s time to install the new one. This step is key to ensuring a smooth and safe running experience on your treadmill. Here’s how to properly position, align, and tension the new treadmill belt:
- Position the New Belt on the Deck: Lay the new belt flat on the treadmill’s deck. Ensure it’s correctly placed, with any belt seam or directional arrows (if present) facing the right way, following the manufacturer’s instructions.
- Align the Belt with the Rollers: Place the belt over the front roller, then over the rear roller. If you removed the front roller earlier, now’s the time to reinstall it with its mounting bolts.
- Center the Belt: The belt might not be perfectly centered initially. Adjust its position on the rollers so that it’s equidistant from both sides of the treadmill deck.
- Adjust Rear Roller Bolts for Tension: Retighten the belt by evenly tightening the rear roller bolts on both sides, turning them clockwise. The correct tension allows you to lift the belt about 2 to 3 inches off the deck at the treadmill’s midpoint.
- Check and Adjust Belt Centering: Run the treadmill at a low speed without walking on it and observe the belt’s movement. It should remain centered. If it drifts, stop the treadmill, turn it off, and adjust the tension on the drifting side by slightly tightening the corresponding bolt.
- Adjust the Deck (If Needed): In some cases, adjusting the deck might be necessary for smooth belt operation. This could involve leveling the deck or adjusting its position. Consult your treadmill’s manual for specific guidance.
- Final Tension and Alignment Check: After centering the belt, perform a final tension check. The belt should be tight enough to prevent slipping when you walk on it but not so tight that it strains the motor.
