How to Align a Treadmill Walking Belt


One of the most commonly reported issues that treadmill owners run into is that of the walking belt gradually slipping off of one side of the track. This may lead to the belt feeling loose under your feet while running or walking. The dislodged belt may also be visibly set off to one side while the treadmill is in motion.

It's important to keep treadmill walking belts properly aligned for a number of reasons. For starters, if a belt becomes poorly aligned, it could actually pose a danger to the person using the treadmill. After all, a belt that's not properly aligned won't have the right amount of tension, which could lead to loosening and make walkers/runners more prone to slipping. Furthermore, if the belt isn't re-aligned, this could also lead to premature wear and tear on the machine itself. Fortunately, aligning a walking belt on a treadmill may be easier than you think; read on to find out how to perform this repair.

For Rear-Roller Adjusting Belts

Many treadmills have belts that can be adjusted using the rear roller, or the one furthest away from the controls of the machine itself. Therefore, it's important to note that this tutorial will focus only on rear-roller adjusting treadmills.

If the Belt Slides to the Right

If the walking belt has begun to slide off to the right side of the roller, use an Allen wrench to either tighten the bolt on the right side of the roller or loosen the bolt on the left side. Be careful, though. When tightening and loosening bolts, less is more. Perform only a quarter-inch turn at a time. Test your work by turning the treadmill on to its lowest possible setting. If the belt seems to be properly aligned, your work is done. If not, you may need to adjust further; just be sure to do so in small increments.

If the Belt Slides to the Left

If you find that the belt slides to the left of the roller while the treadmill is turned on, then you'll need to follow the same instructions above with one exception. Instead of loosening the bolt on the left and tightening the one on the right, you'll need to loosen the one on the right and tighten the one on the left. Maintain the same gradual, quarter-inch turns and check your work carefully.

How to Install The Schwinn Airdyne Wedge Pin

Installing the Schwinn Airdyne Wedge Pin

The following instructions for installing and removing wedge pins are applicable to Airdyne bike models AD3, AD4 and some Pro/Comp models. Each wedge pin has a flat edge that mates with a corresponding part. All parts that require a wedge pin will have a flat edge in one location. This allows the wedge pin to slide into position. To assemble the eccentric arm and cartridge, slide the eccentric onto the post of the cartridge, install the wedge pin and put the washer and nut on the back side.

Removing the Wedge Pin

To remove the wedge pin, use a wrench to loosen the nut at the top until there is a bit of play behind it. Use a rubber mallet to tap the top until the wedge pin begins to move down through the opening. Once the wedge pin slides easily, take the nut completely off the wedge pin and push the wedge pin out of the assembly. If the wedge pin has been installed on a machine for an extended length of time, it may be somewhat difficult to remove.

Installing Wedge Pins in the Proper Direction

When installing wedge pins during the crank arm assembly on Airdyne bikes it is important to be aware of the direction in which the wedge pins are installed. The crank arms on each side of the assembly should be at exactly a 180 degree angle from one another. It’s essential that the wedge pins on each side of the assembly are installed in opposite directions to ensure the crank arms are positioned correctly. If the wedge pin on the eccentric side has the nut up and the stud down, the wedge pin on the opposite side should be reversed.

Tightening the Assembly

Inside the nut, there is a nylon insert. The nut must be tightened sufficiently for the threads to grasp the nylon insert for it to hold properly. Proper tightening is accomplished by pushing the wedge pin in and starting the nut manually. Use a wrench to ensure it is thoroughly tightened. There should be no play in it at all. As a precaution, check the part after it has been installed for a while to verify that the nuts remain tight. If they are not seated properly, once the machine is in operation, they will begin to move. Even though the wedge pin may be seated correctly, if the nut isn’t tightened properly, there will be play between the moving parts that will cause the system to wear out prematurely.

How To Lubricate A Treadmill Deck Using Liquid Lube in 4 Easy Steps

Video about How to Lubricate a Treadmill using Liquid Lube

  1. To begin, clean the deck and belt by loosening the rear roller bolts 10 turns as seen in the video. It is best to loosen each side five turns and then repeat the process. Now that the belt is loose you can take an old towel and place it under the belt as shown in the video. Move the towel up and down the deck, then using your hands pull the belt around half way to ensure you have completely cleaned the back of the belt. Then remove the towel.
  2. Open your lube packet and use half of the package to make a half circle on the deck, from the front outer portion of the deck toward the center and then back to the outer edge. Use about half the package for this arc. Now repeat the process on the opposite side. Be sure to wipe up any excess oil as it is very slick!
  3. Use your hand to move the belt around some more to begin spreading the lubricant out.Now tighten the rear roller bolts back to the exact amount of turns they were loosened previously.
  4. Power on and start the machine and let it run slowly for a few seconds to make sure the belt is staying aligned in the center of the deck area. If it is not centered correctly, make minor adjustments to correct the issue. Tighten the left bolt to move the belt to the right and tighten the right bolt to move the belt to the left. Now walk on the belt for a minute or so to fully distribute the lubricant.

2014 Seasonal Flu is on the Rise

Gym Wipes, Disinfecting Wipes & Antibacterial Wipes

People who care about fitness should care about influenza. Seasonal flu is a serious problem every winter, and the current trends for the 2014 flu season show influenza on the rise. It can spread quickly anywhere a crowd gathers.

Even a light case of the flu can make life miserable for more than a week, spoiling work, workouts, and play. Yet it is possible to fight the spread of flu.

Protect your members from:

•Flu complications
•Flu downtime
•Lasting lethargy and sub-par performance

Health clubs and fitness centers are especially vulnerable to the flu, because the members all share the same equipment, and often everyone grabs it in the same place. Nobody wants to take the time to worry about germs, but they appear each flu season, and a swipe with a personal terrycloth towel will not wipe them away

The Problem

Germs spread easily where people spend time close together, and people can spread the flu and many other illnesses before they even feel sick. As the CDC says, “Most healthy adults may be able to infect others beginning one day before symptoms develop and up to five to seven days after becoming sick.” Flu virus survives on surfaces too, according to the United States Centers for Disease Control. Yet a few simple precautions will keep your gym from being “Where I got the flu.”

How do you fight influenza? Fitness helps people stay well, but so does hygiene. Providing wipes and towelettes shows athletes that you are looking after their health and safety, and protecting everyone from a disease that can spread like wildfire. Clean and sanitize all the surfaces your athletes touch, to look out for the members of your fitness facility.

The Solution

The three sanitation concerns for fitness facilities are exposed skin, hard surfaces, and soft surfaces. Sportsmith provides solutions for all three.

1.  Anti-Bacterial wipes contain a gentle effective sanitizer especially formulated for use on the body. It smells effective but not strong, and dries quickly, leaving skin feeling fresh. Making wipes available is one easy way to prevent the spread of influenza and other infections among your members:

• Use on hands, arms and legs, wherever you touch equipment
• Safe and effective on facial skin

2. Disinfecting towelettes clean hard surfaces. They kill viruses, fungus and bacteria, including staph. This product is gentle enough to use without gloves, yet highly effective. Use on:

• Metal
• Plastics
• Laminates
• Rubber
• Plexiglass

Flu complications can include pneumonia, meningitis, and encephalitis. These are all rare. However, downtime from the flu is common. Influenza takes its victims out of action for up to ten days, and sometimes longer.

Even when someone gets over the flu, they may still not feel completely back to normal. It can take months before an athlete functions at peak again. Influenza and other viruses can really put a dent in performance.

Protect your members from the flu and many other contagious diseases, and keep your facility sparkling. Take care of your members, with economical body wipes, towelettes, and cleaning wipes from Sportsmith. Your members will know you care.

Best of IHRSA 2013

IHRSA 2013


IHRSA 2013

What could be more exciting than getting a sneak peak on what’s to come in the Fitness World?!! This year at IHRSA all the fitness products and equipment were nothing short of amazing! The only bad thing is we wish we could have stayed longer!

First we got to start off our trip at the Stairmaster 30th and Schwinn 10th Anniversary party. It was great to mingle with some wonderful people in the fitness community! It was great listening to the speakers and having some alumni there to check out how far the Stairmaster has come after 30 years! Did you know that Sportsmith is Stairmaster and Schwinn’s authorized product support center? Yup! So give us a call if you have any questions!

We started our morning off right with an early morning workout by Xerciselab. We checked out the Build Lab class. This is a workout that uses your body weight as resistance. My thighs are still burning from all the squats!

Then we were off to the trade show floor. Oh the smell of new equipment… Ok, maybe it was the Chobani Greek Yogurt we were smelling... Still amazing! We were in awe of all the new technology that has come out for the new equipment. A hot new product we loved? The Grid Mini by Trigger Point- we may not leave home without one now. I was dying to lie down and try it out along with the ColdRoller. Unfortunately the Grip Mini is not available until April. We were also able to hop onto Star Trac’s new TreadClimber®- love it! Some popular items this year seem to be surf board workouts (SURFSET Fitness, FreeMotion Fitness, and StrongBoard Balance), Suspension training (TRX, Jungle Gym XT) and different functional training stations (SYNRGY 360T by LifeFitness and CT8 Fitness Training System by Tuff Stuff Fitness).

CrossFit Open 2013

crossfit equipmentIn spirit of the CrossFit Open kicking off this past Wednesday we thought we would join the excitement! Want to be in the know about CrossFit?  We hope to share a bit of our knowledge and love for the sport with you!!

What is it?

We are so glad you asked! The Open is a worldwide CrossFit event that takes place this year from March 6 - April 7. Each Wednesday a new Open workout is posted and they have until that Sunday to complete the workout.  Participants are able to complete the workout at a participating affiliate gym or videotape their performance and submit it to the Games website (We will touch base on the Games later). CrossFitters are able to participate in the Open as an individual or a team of 3 men & 3 women.  At the end of the 5 weeks the Open’s top athlete individuals and teams in each region will move on to the Regionals.

The regionals are a three day event where the top athletes from each region have to compete in a series of brutal workouts to hopefully secure an individual or team spot in final event, The Games.  At the end of each Regional only 3 men, 3 women and 3 teams will advance to the CrossFit Games.

On July 22-28 The Reebok CrossFit Games will take place in California where the Fittest on Earth™ will battle their way to the top!  To find out more about the Games check out

The popularity of CrossFit over the past few years has blown up. The 2011 CrossFit Open had 26,000 participants which is nothing compared to the 2013 Open which has over 130,000 participants! Every year the competition of the Games becomes fiercer with the wide-spread growth and popularity.

What equipment do they use?

CrossFit workouts include a variety of different products for their workouts. However, you will not find the large equipment you see in everyday gyms such as weight machines, ellipticals or treadmills. Once you walk into a CrossFit gym you will understand that it is not your average gym. It is filled with kettlebells, dumbbells, Olympic bars and bumper plates, soft medicine balls, jump robes (You thought they got rid of those after middle school right?!), Plyo boxes, gymnastic rings and rowers.  CrossFit doesn’t use machines – They make them. You can check out some great CrossFit packages or individual products mentioned above here,

Want to join the craze?

You can find any local CrossFit affiliate on the CrossFit Community site, At any of these locations they should have all the appropriate equipment for your WODs (Workout of the Day) and to train you properly to get you ready for the Open 2014!

If joining an affiliate isn’t exactly your thing training from home isn’t farfetched! On the community site you can learn all the ins and outs of CrossFit. On the training page you are able to learn about different certifications you can receive in CrossFit to become an instructor, they provide a list of exercises with videos and demonstrations and even give you several different WODs to try it out on your own.  We defiantly encourage you to take some courses if you are going out on your own so you know to properly do the exercise movements.

Love it yet?

We are giving you fair warning here… CrossFit is humbling, addictive and intense. If you join a gym the athletes will mostly likely be a second family. The atmosphere at any CrossFit event is more intense and energetic then anything previously experienced. Fellow athletes and spectators cheer on people they have never seen or heard of like it’s their favorite football team about to win in overtime.  Even though CrossFit can be very competitive the comradery within CrossFit athletes is what demonstrates what this culture is all about.
