Treadmill Doctor Replacement Belt for the Horizon DT650 Treadmill

When a customer calls Treadmill Doctor with a problem with their treadmill, one of the first questions I ask is, "Have you been lubricating the walking belt on your treadmill, and if so, with what?" I ask this question in order to maintain optimal performance regarding the treadmill. I recommend lubricating the walking belt at least two times a year. When the belt on any treadmill lacks lubrication, the belt dries out, and this creates increased friction. This increased friction wears the belt out prematurely. As belts wear, it can cause a lot of problems with the motor and electronics of the treadmill. There are fibers on the backside of the belt that start to break down, and this increases the friction between the belt and the surface below the belt, which is called the deck. This extra friction means that the motor has to work harder to maintain the desired speed, and the motor controller has to put out more energy in order for the motor to maintain that speed. The result is that the motor controller starts to get hot and eventually, they fail. The motor and the electronics in the treadmill can be very pricey to replace. This situation causes a higher than normal amperage to be used by the treadmill that pops the circuit breaker in the house or on the machine.

Just like your car, treadmills need to be maintained or serviced from time to time. Regular service for your car helps to extend the life of your car. The same holds true with your treadmill. Regularly lubricating the walking/running belt helps to extend the life of the belt and the treadmill. However, just like the tires on your car wear out and you will have to replace them, the walking/running belt needs replacing as well. When I put new tires on my car, I don't put seconds or inferior tires on it. I want a good product at a reasonable price. I know that the tires need to be of good quality because a blowout at high speeds could be disastrous. I can draw the same conclusion when replacing the belt on my treadmill. For one, replacing the belt is going to involve my time and energy or, I'm going to have to pay someone to do it. With that thought in mind, I want a good quality belt for my treadmill so that I don't have to do it again.

When a customer calls and wants to know what belt they should buy, I go through all the pros and cons of each type of belt. I ask how many people use the treadmill and how much it's used. Putting a single ply belt on a treadmill used by three people each using it three times a week isn't going to last very long. Conversely, someone who is selling a treadmill may want to put on a very inexpensive belt in order to be able to sell the treadmill.

Treadmill Doctor sells a single ply replacement belt and a 2-ply replacement belt for the DT650. The original belt that comes on this treadmill is a 1.6 mm and is technically a 2-ply belt. However, the Treadmill Doctor replacement belt is a thicker more durable belt that holds up much better than the original equipment belt that came with the treadmill. In addition, Treadmill Doctor offers a standard and a professional grade of the 2-ply belt. The standard grade belt comes with a one-year warranty and is less expensive than the Professional grade belt, which comes with a lifetime warranty. The warranties on these belts cover the failure of the belts or in the rare case, if the seam starts to separate.

By replacing the walking belt with a Treadmill Doctor walking belt, you are putting on a better quality belt that will give you many years of trouble-free use. Most people do a lot of research before they make a large purchase like a treadmill. They want one that has all the features they need and one that will stand the test of time. I'm going to draw from the car analogy again. When I'm looking for a new or used car, I don't just go and buy the first one I see. I do some research on it. I look for a car that is within my budget that has all the bells and whistles that I want in my car. I'm sure the same is true for replacement belts for your treadmill, especially with the usage of the Internet today. Treadmill Doctor belts come pre-lubricated with our own lubricant. We also include an additional tube of lubricant with every belt shipped, which gives the end-user an approximate 1-year supply. Treadmill Doctor gives the customer a great deal, considering the lubricant and shipping would cost about $16.99. The cost of the belt is also very competitive, if not better than the original manufacturer’s belt which costs $99.99 plus shipping. When you combine the quality of the belt, the warranty, the price and the lube, I can't think of any reason not to purchase your replacement belts from Treadmill Doctor.
