The Basics of Treadmill Lubricant
No one buys a car without expecting maintenance duties, yet day people buy treadmills every day without understanding the need for lubrication. Whether you spent $800 or $8,000, the treadmillâs primary parts of concern here are the deck, belt, and motor. To prevent those parts from coming loose or needing replaced, all that’s required is a few simple steps once in a while.
The actual step-by-step process of how to lubricate a treadmill and where to get the proper lubricant, is as simple as replacing the windshield wiper fluid in your car. And while the best home treadmills require little to no maintenance, cheaper treadmills require a little more to keep running smoothly. Even if your tread belt appears to be operating well, be sure to rub in a little lube as needed to prevent future issues. Here are some frequently asked questions we receive about treadmill lubrication.
Why Do Treadmills Require Lubricant?
Big or small, the treadmillâs primary parts of concern here are the deck, belt, and motor. The deck is the smooth surface upon which youâll be walking or running. Most treadmill decks these days are made from Medium Density Fiberboard (MDF), which is also commonly found in kitchen countertops and cabinetry. Smooth, solid, and hard, it provides a great surface on which a tread belt will be pulled by way of rollers connected at either end. This process is all driven by a motor.
Lubricating a treadmill deck at appropriate intervals is necessary to keep all these parts running smoothly. Treadmill belts can be found in single-ply or 2-ply, with 3- or 4-ply occasionally found. A single-ply belt is simply the belt youâll see on the surface, but a 2-ply belt has an undercoating or cotton, silicone, or some other type of fiber to help it run more smoothly across the MDF, which remember, is made of a material that looks like a kitchen countertop. Cheaper, single-ply treadmill belts are a little rougher a rub on the surface of the deck compared to the 2-ply. But both will need a little lubrication from time to time to allow a smooth run.
If youâve ever seen a treadmill in action youâll understand why theyâre referred to as âdust magnets.â The whirring motion of that machineâs roller-driven belts will suck up every spec of dust and pet dander around. Youâre also likely to bring a bit of dirt with you to the tread every time you step on with your sneakers. Fear not, itâs just life. But where does that dust wind up? Underneath the tread belt and within the motor carriage. Jog after jog, those little specs will begin to provide the stuff of which friction is made, and thatâs when your belt begins to wear.
A rougher ride also requires more work for your rollers and thus your motor. The smoother the run, the longer the life of all the working parts. The MDF decks on pricier units are coated with a phenolic resin, which is the same substance used on billiard balls. Cheaper units may costs less than those with MDF as a deck. They might have composite or particle board and won’t be coated as well. You can understand why those would be more prone to belt wear and roller fatigue, particularly if the belt is a cheaper single-ply.
Finally, consider that youâll be sweating a bit during your run, and even if youâre just walking, air moisture abounds. Your belt will be getting damp then dry between uses, especially if itâs a foldable unit you plan to roll away into a closet between runs. That dust and dryness of storage when combined with the sweat and heat of the use will make the belt brittle over time if left without lubrication.
- Treadmill lubricant reduces friction between the tread belt and motor, significantly extending machine life.
- Treadmill lubricant helps prepare the machine for storage. Without it, the belt can become brittle and break.
- Preventing a tread belt breakdown is always cheaper than buying a replacement.
What’s the Worst That Can Happen?
The worst-case-scenario is youâll need a new treadmill, which is bad. Warranties on these machines run the gamut of a year to lifetime for the deck and the same with the motor. Most machine warranties give at least 90 days for parts and labor, but not all. But if you consider the amount of force youâll be putting on that machineâs deck, the constant changing of temperature and moisture from hot to cold, plus dirt, you can understand why the deck and motor might simply give up on you without lube.
A quick search online will demonstrate that replacing treadmill belts can add up fast, with examples like a typical ProForm belt running $129.99. Pre-lubricated and 2-ply, it should do the trick given you size it correctly, but that’s a good chunk of change. A replacement 3 horsepower motor from that same manufacturer could run you $300. Replacement rollers trend upwards of $172 and replacement walking decks are about $347. All totaled, thatâs $948.99 without shipping, handling, and time spent installing. If youâre still making payments thatâs a bit much to swallow.
On the other hand, an 8.4-ounce of silicone treadmill lubricant can be had for $8.99 . It just doesnât make any sense to ignore regular maintenance.
Will Any Old Lubricant Do?
Negatory. One should never, ever use WD-40 or other sprays meant for metal parts. Remember, the undercoating of a 2-ply deck is made of material which can be dissolved with these chemical sprays.
Most of your better treadmills when purchased will come with a container of silicone lubricant, as well as instructions for application. Each machine is a bit different, but most are similar enough I can assure you it isnât rocket science. Most treadmill lubricants are made of some kind of silicone-like substance and that’s what you need to use. Baby oil, vegetable oil, or other alternatives are a recipe for disaster.
Precor happens to manufacture a self-lubricating treadmill with a reversible deck, and with that comes a lifetime warranty on the frame and welds, a 10-year guarantee on parts and wear items like the belt, and one year labor. Horizon treadmills meanwhile are now coming with a message system which will flash âLube Beltâ every 300 miles. With the purchase of a new treadmill typically comes a bottle of the manufacturerâs brand of lubricant, and from there itâs easy enough to purchase more online. This is certainly something to consider when shopping for a treadmill.
How Much and How Often?
Yes, there is such a thing as too much of a good thing. You certainly donât want to over-lube the machine. A good rule of thumb is to lubricate every three months or 40 hours. Youâll probably want to use an ounce per application, with half an ounce on each side during the process. If youâre a heavier-than-average person, use the treadmill more frequently for longer runs, or have a particularly dusty house, you might want to adjust a bit.
Keep in mind that even if you havenât used the treadmill in a few months, itâll still require the lube, just like car parts which havenât moved in a while. Older models wonât necessarily alert you to the need to lubricate like Horizon, but you might start to feel differences in the belt or tread. Before any damage is done, itâs best to take action.
Lower-cost units with smaller motors, thinner rollers, and single-ply belts might likewise need more care than some of the upper-budget models with more expensive parts. As a general rule, the shorter the warranty offered, the more responsibility for care youâll be assuming.
