There is an easy way to replace the treadmill belt. I’m sure you have been there before, wishing you could just tear the whole thing apart and start over. You have tried taking out the bolts holding the belt in place, but they are so corroded you cannot get the belt apart.
Then you notice that the screws to the treadmill are all rusty and have started to look funny… there is a better way!
Where can I find a new belt?
The best place to start your search is online. There are many treadmill parts and accessories stores on the internet that carry countertop treadmill parts. Sometimes they will even say they carry new belts, but be careful if this is the case. If you buy from a non-online retailer, you may run the chance of getting a bad model, a scratched countertop, or the wrong brand.
We get down to business
Before you do anything with your treadmill belt, first take a close look at the belt itself. You should be able to see the two different pulleys that are used to balance the walking belt on top of the deck. You need to be able to loosen both of them with one hand. The most common method of loosening them is to use Allen’s sockets.
Step 1. Bolts
Loosen both bolts of the old running belt with your new Allen’s sockets wrench. Remove the old belt to a nearby surface. If you have a multi-purpose treadmill, it is okay to recycle the old running belt. Otherwise, separate the belt into several pieces and put them in a large plastic garbage bag.
Then you should remove the bolts from the treadmill’s deck. Some models will have side plates that need to be removed before you can replace the running belt. If this is the case with your machine, you will see the plates moving when you run.
Step 2. Main part
Loosen the screws on the countertop with your Allen’s sockets wrench. If you are replacing an older model with a new countertop, you may have to remove the existing countertop before you can replace the belt.
If you are replacing an older model with a new countertop, you may need to remove the existing countertop before you can replace the belt. If you are replacing an older model with a new countertop, you may have to remove the existing countertop before you can replace the belt.
Step 3. Replacement
Remove the treadmill belt and set it aside. Place the new belt on the rear roller of the machine and secure the belt with several bolts. Tighten the belt bolts. Now you can replace the screws on the deck.
Put the treadmill on the deck. Run or walk on it while it is in the “on” position. If you hear grinding noise when you walk or run, there are probably two screws that need to be adjusted. Adjust the screws to position the belt on the backside of the treadmill.
If your machine has an enclosed deck, like many treadmills sold today, you will need to remove the exterior trim around the neck and front of the treadmill. You will probably need to use Allen’s screwdriver to remove the trim around the entire treadmill. There will be a plate inside the treadmill housing that will hold the running belt in place. This plate can be locked or unlocked with Allen’s key. Some models of treadmills will not lock or unlock the plate; instead, they will lock in place.
Step 4. Putting everything back
Adjust the two screws that are located on each end of the running belt and then remove them. In most cases, the moving pieces will break away from the treadmill belt. Use a screwdriver to pry the two halves separate until the moving pieces can move freely.
Use Allen’s key to lock the belt in place or to position it so that it matches the other components of the treadmill.
How To Replace Treadmill Belt – Replacing the belt is a lot simpler than you might think. It is best to replace the old belt with the same material as the new one to keep the belt working properly. If there are only small areas where the belt meets the deck, it is not a problem to tighten the belt a bit to adjust. However, if you have a very large area to adjust, it is a good idea to have a professional make the replacement.
