How To Fix The Treadmill Belt Properly With To-do Manual

Are you tired of running on a treadmill with a slipping or loose belt? Don’t worry; you’re not alone. A loose treadmill belt can be frustrating and can even lead to injury. Fortunately, fixing a treadmill belt is easier than it seems. In this ultimate guide, we’ll show you how to fix the treadmill belt step by step.

What Are The Problems That Can Creep Up?

If you encounter a slipping belt on your treadmill, refer to your owner’s manual for guidance on troubleshooting the issue. It’s essential to perform regular maintenance to avoid damage and misalignment of the belt and deck. You can find a lasting solution by identifying the root cause of the problem.

5 Reasons For Treadmill Belt Slipping

Lack Of Lubrication

Regular lubrication is crucial for the smooth operation of the treadmill. Due to frequent use, friction between parts is inevitable. Failure to lubricate the belt correctly can cause it to slip, which is the most common issue experienced when using a treadmill. 

Using the correct lubricant is essential as a water-based silicone solution may evaporate quickly, leading to repetitive lubrication. Don’t let frustration ruin your workout; use the right lubricant to prevent this issue.

The Drive Belt Is Too Loose 

The drive belt is a crucial component of a machine located at the front, running between the motor and the first rollers under the deck. It is positioned similarly to the treadmill belt running in the center alignment, supporting the completion of an operating circle over the running deck. 

Over time and use, all kinds of drive belts wear out, but if not taken care of on time, the belt tends to wear out quicker than expected, which can impact the working of the treadmill. Improper fixing or loose alignment of the drive belt can also turn into a circuit breaker. 

A worn-out drive belt can be identified when stepping on the treadmill as the belt stops along with the front rollers and pulley. The treadmill belt starts slipping if the drive belt is loose between the front rollers and motor. 

While tightening the drive belt is easy, it is only a temporary solution. Overtightening can increase the operating amp, leading to later motor burnout.

The Walking Belt Is Too Loose Or Tighten

The walking belt is a crucial part of a treadmill, and it’s essential to maintain it properly to ensure a smooth and efficient workout experience. Here are some key points to keep in mind:

  1. The walking belt is typically made of PVC, although it may appear rubber.
  2. Over time, the belt can become stretched and slip from the track, which can cause disruptions during workouts.
  3.  It’s essential to ensure that the tension on the walking belt is neither too loose nor too tight.
  4. When the belt is too loose, it may slip from its center alignment, which can cause problems during workouts.
  5.  Over-tightening the belt can cause pressure on the motor and damage other costly parts of the treadmill.
  6. To maintain the treadmill belt, it’s recommended that there’s a distance of 2-3 inches between the running deck and the running belt.
  7. Follow these guidelines to avoid the belt slipping and other problems arising.

The Pulley On The Front Roller Might Have Lost Grip 

The pulley located at the front of the equipment is responsible for supporting the weight of the treadmill belt and ensuring it can operate smoothly. 

However, if the pulley becomes misaligned or loses its grip on the belt, it can result in accidents where the belt slips. This can be observed during use when the front rollers and walking belts remain stationary while the pulley and drive belt are in motion. 

The front rollers are crucial in driving the belt, and if they become misaligned, the belt can slip and interrupt the treadmill’s operation. Although this issue may be complex for some to understand, it is a critical problem that can cause the treadmill belt to shift from its central alignment.

Worn Out Treadmill Belt 

Every piece of equipment has a shelf life. Even with proper maintenance, they cannot be extended. Moreover, multiple individuals’ repeated use of the treadmill belt can lead to wear and tear, resulting in occasional slipping accidents. 

Despite exploring various measures to prevent belt slipping, they all yielded different results. The slipping belt is a clear indication that it needs to be replaced. 

Secondhand treadmill belts tend to wear out faster than expected due to prolonged usage, causing them to stretch out. A long-term solution is imperative to prevent frequent belt slipping.

Replacing Or Realigning The Slipping Drive Belt

If you’re facing the issue of a slipping treadmill belt, here are the steps you can take to fix it:

1. Turn off the treadmill and unplug it from the electrical outlet.

2. Locate the drive belt, which is situated between the motor and front rollers.

3. Check if the belt is loose. If it is, you can temporarily tighten it. However, this might put more pressure on the motor.

4. You can also use dressing spray to treat the problem temporarily. But keep in mind that this is not a permanent solution.

5. If you want a permanent fix, the best option is to replace the drive belt. This should be done at an authorized service center following the manufacturer’s manual.

6. Avoid getting the treadmill repaired outside, as this can void the warranty conditions.

By following these steps, you can fix the problem of a slipping treadmill belt and ensure the smooth functioning of your machine.

Tightening Of Treadmill Belt When Too Loose

If the distance between the treadmill belt and the deck is more than 3 inches, it needs to be tightened as per the instructions in the owner’s manual. 

The belt tends to stretch regularly, causing it to become loose and misaligned. This can be checked by lifting the belt from the deck and confirming it is within the allowed distance of 2-3 inches. 

To tighten the belt, use a hex key or Allen wrench to adjust the rear bolts of the treadmill, which are usually included with the purchase. Switching to metal bolts is recommended to ensure the loose belt’s proper tightening and avoid slipping. 

If the plastic adjustment bolts are not doing the job, they can be replaced with metal ones using a fixing kit or replacing the end caps.

Loosen The Belt In Case Of Too Much Friction.

It is vital to avoid over-tightening the belt on your equipment as it can cause excessive tension on the motor and increase friction between parts. 

To ensure the proper distance between the deck and the treadmill belt, refer to the manufacturer’s guide, which suggests a 2-3 inches range. 

After lubrication, the belt may become too tight and slip, but it can be adjusted back to its original position using an Allen wrench or hex key, as stated in the owner’s manual.

Realign The Pulley And Front Rollers

If the pulley that operates the circular motion of the treadmill belt or front rollers becomes misaligned or shifts from its position, the belt may slip from its centered alignment. 

Although it is possible to fix this issue by drilling a pilot hole and using a short sheet metal screw to secure the pulley, it is recommended that you seek the assistance of a technician. 

Alternatively, replacing the pulleys or rollers is a better option for optimal machine performance. 

To check the alignment, use colored tape and a permanent marker, and then decide whether to tighten the pulley or replace it. Due to warranty implications, it is strongly advised to seek professional advice before taking any action.
