A treadmill is a popular piece of exercise equipment that offers convenience and versatility for indoor workouts. However, over time, the constant impact and stress of running or walking can cause wear and tear, leading to issues like a cracked treadmill deck. 

While this may seem like a daunting problem, fear not! In this article, we will guide you through the step-by-step process of fixing a cracked treadmill deck, ensuring your equipment’s longevity and your continued fitness journey.

Assessing the Damage

Before diving into repairs, it’s crucial to assess the severity of the crack and determine if it’s something you can fix yourself or if professional assistance is required. Examine the deck carefully and look for any visible cracks, splits, or separations. 

If the damage is minor, you can likely fix it on your own. However, if the crack is extensive or poses a safety risk, it’s advisable to contact a treadmill technician for assistance.

Gather the Necessary Tools and Materials

To begin the repair process, you’ll need a few tools and materials. Make sure you have the following items on hand:

  • Screwdriver or Allen wrench (depending on your treadmill model)
  • Sandpaper or a sander
  • Epoxy adhesive
  • Clamps or weights
  • Wood filler or putty
  • Deck replacement kit (optional, depending on the severity of the crack)

Removing the Treadmill Belt and Deck

To access and repair the cracked deck, you’ll need to remove the treadmill belt. Start by unplugging the treadmill from the power source for safety. 

Consult your treadmill’s user manual for specific instructions on belt removal, as the process may vary based on the model. In most cases, you will need to remove the motor hood, loosen the tension on the belt, and carefully slide it off the deck. 

Once the belt is removed, use a screwdriver or Allen wrench to detach the deck from the frame.

Repairing a Minor Crack

For minor cracks, you can fix the deck using epoxy adhesive and wood filler. Follow these steps:

  1. Clean the cracked area thoroughly, removing any dirt or debris.
  2. Use sandpaper or a sander to roughen the surface around the crack, allowing better adhesion for the epoxy.
  3. Apply the epoxy adhesive to the crack, spreading it evenly. Make sure to use an adhesive suitable for wood repairs.
  4. Press the crack together firmly and wipe away any excess adhesive.
  5. Place clamps or weights over the cracked area to hold it in place while the epoxy dries.
  6. Allow the epoxy to dry completely as per the manufacturer’s instructions.
  7. Once the epoxy has cured, use wood filler or putty to fill any remaining gaps or imperfections on the deck’s surface.
  8. Sand the filled area until it’s smooth and flush with the rest of the deck.

Repairing a Major Crack or Deck Replacement

In the case of a significant crack or if the deck is beyond repair, you may need to consider replacing the deck entirely. Follow these steps:

  1. Remove the cracked deck from the treadmill frame.
  2. If replacing the deck, follow the manufacturer’s instructions to install the new deck. Alternatively, if your treadmill model offers a deck replacement kit, refer to the provided instructions for installation.
  3. If a replacement deck is not available, you can explore the option of contacting the manufacturer or a professional technician to source a suitable replacement deck.
  4. Once the new deck is installed, reattach the treadmill belt by reversing the previous steps.

Ensuring Proper Deck Maintenance

Prevention is always better than cure when it comes to maintaining your treadmill deck. To extend its lifespan and minimize the risk of cracks, follow these maintenance tips:

  1. Regularly inspect your treadmill for any signs of wear, including cracks or splits in the deck.
  2. Lubricate the treadmill belt according to the manufacturer’s recommendations to reduce friction and strain on the deck.
  3. Avoid placing excessive weight on the treadmill, as this can strain the deck and lead to cracks.
  4. Clean the deck regularly, removing any dirt, dust, or debris that can accumulate and cause damage over time.
  5. Consider using a treadmill mat or placing the treadmill on a stable, level surface to reduce vibrations and stress on the deck.

Safety Precautions

During the process of repairing a cracked treadmill deck, it’s essential to prioritize safety. Here are a few precautions to keep in mind:

  • Always disconnect the treadmill from the power source before starting any repair work to avoid the risk of electric shock.
  • Use caution when handling tools, especially sharp objects like screwdrivers or sandpaper, to prevent injury.
  • Follow the manufacturer’s instructions and guidelines for your specific treadmill model to ensure proper disassembly and reassembly.
  • If at any point you feel unsure or uncomfortable with the repair process, it’s best to seek professional assistance.

Seeking Professional Help

While minor cracks can often be repaired by following the steps mentioned earlier, there may be instances where professional help is necessary. 

Here are a few situations in which you should consider contacting a treadmill technician:

  • The crack is extensive or severe, making it difficult to repair on your own.
  • You lack the necessary tools or experience to perform the repair safely and effectively.
  • The treadmill deck is made of specialized materials or requires specialized techniques for repair.
  • The treadmill is still under warranty, and attempting repairs on your own could void the warranty.

Remember, it’s always better to seek professional assistance if you are unsure or if the damage is significant. Treadmill technicians have the expertise and knowledge to handle complex repairs and ensure the safety and functionality of your equipment.


Repairing a cracked treadmill deck is a feasible task that can save you time and money. By following the steps outlined in this article, you can restore your treadmill to its former glory and continue enjoying its benefits for years to come. 

Remember to assess the severity of the crack, gather the necessary tools and materials, and carefully follow the repair instructions. With a little effort and attention, your treadmill will be back in top shape, ready to support your fitness goals.
