Drive Belt Installation for Treadmills

The drive belt is used by the motor to drive the treadmill walking belt via the front roller pulley. A drive pulley is mounted on the roller and the roller has knurling or a sleeve to help it drive the walking belt. The treadmill console detects the current speed of the treadmill by monitoring the movement of a magnet mounted on the front roller pulley with a reed switch or by using an optic switch which monitors an optic disk mounted either on the front roller or on the motor shaft. If the sleeve moves to the side, you will not be able to keep the belt centered and many optic disks can be warped if pushed to the side by the sleeve if it moves, but we do have replacement sleeve kits if needed.


Steps to Replace Drive Belt-

1) Remove the safety key and unplug the treadmill from the wall outlet.

2) Remove the screws securing the motor hood and gently remove the motor hood.

3) Using an Allen wrench provided with the treadmill, loosen the two rear roller adjustment bolts until the rear roller comes into contact with the walking board. Turn the bolts and equal number of turns on each side and keep a count of how many turns you made so you will know how to properly re-tension the walking belt.

4) Remove the drive belt from the motor pulley. Place a screwdriver between the pulley and the belt and turn the pulley by hand. Use the screwdriver to guide the belt over the edge of the pulley. Be careful with the screwdriver to prevent damage to the pulley.

6) Mark the position of the front roller axle on the front roller bracket above the front roller adjustment bolt using a Sharpie marker so you will know where to put the bolt back into position. Remove the front roller adjustment bolt if your treadmill's front roller has a pitch adjustment bolt. If your treadmill does not have exposed roller bolts you will need additional instructions. Please see the troubleshooting section on our website for further help.

7) Gently slide the front roller from out of its mounting position on the frame. Do NOT remove the roller from the walking belt.

8) Slip the old drive belt off the roller and loop the new drive belt onto the front roller pulley.

9) Replace the roller back into its slot on the pulley side and re-tension the front roller pitch bolt to its proper place using the Sharpie mark as a guide.

10) Using the screwdriver, loop the drive belt over the motor pulley. Many Icon units originally had the drive belt misaligned by design (if you can believe it). This was to use the side load of the drive belt in order to keep tension lower. It does lower amp draw for the machine and replacing a side load drive belt occasionally is much cheaper than replacing a motor and/or controller so if your original drive belt was off-centered, install the new belt in the same manner.

11) Re-tension the walking belt.

12) Plug in the machine and check the drive belt for slipping. You can use some automotive fan belt dressing on the grooved or contact side of the belt to help it with grip on the pulleys and it will treat the belt as well. We prefer using belt dressing rather than over-tensioning the belt for the aforementioned amp reasons as well as additional stress placed on the drive system parts.

13) Replace the motor cover and test.

14) Make sure the walking belt is not slipping and is properly aligned and your treadmill is ready to use.

I have a Black & Decker sander, model # 7447 and am having problems changing the sand paper.


The 7447 does not have a release lever. To change the belt, you must release tension of the rollers by pushing the front roller straight back until you hear it click and lock in position to change paper. Remove old paper and replace with new paper. Make sure if new paper has directional arrows to install properly.
Now you must release the front roller to put tension on paper. To do this push the front roller from the side that has the adjustment screw. This will release the front roller and allow it to go back into position. Be careful as it pops back quickly and with some force.
Turn on sander and adjust centering of paper with adjustment screw found near the front and side of sander.

Belt stops running although you can hear motor running. How do you replace front roller pulley?


Loosen off the rear roller adjustment bolts, 10 turns each side counterclockwise.
Remove the motor drive belt.
The front roller should now be removable. If you have difficulties, back off the rear roller adjustment bolts 3-4 turns further. Keep track of how many counterclockwise turns so you are able to readjust the belt after replacing the front roller pulley assembly.
Repeat the instructions in reverse once the front roller is in position.

How do I change the walking belt on a Nordic Track EXP 2000?


Hi,

First, remove the motor hood. There are 3 screws at the front, and 2 underneath. The screws underneath will have to be removed by tipping the treadmill over, or pulling the console towards the rear of the machine.

Next, remove the side rails. This is a little tricky because of the cushion adjusters on each side of the deck. If you look underneath the deck, you will see that the adjusters are on rails that are attached to the platform. Remove all of the screws from the side rail and push it toward the rear of the machine while also moving the adjusters rearward. You'll have to kind of move them together until the adjuster slides off the rail. Do both sides.

Remove the rear roller, by loosening the bolts. Don't mess with the front roller unless you intend to replace the motor belt. You don't need to remove the front roller or the walking belt.

There are 4 bolts holding the deck to the frame. The rear ones go through the frame to a lock nut. The front bolts screw into the isolators. Remove them and the deck will come loose. You can slide it out from the walking belt.

Place the new deck next to the old, and start moving the parts over. Make sure the safety decal is on the bottom like the old deck. All of the holes are pre-drilled except for the belt guides. You'll have to measure for these. Now do everything in reverse to reassemble the machine. I'm also attaching instructions on how to adjust the belt.

First, ensure that it is the walking belt that is loose. There is a belt hidden under the hood that connects the front roller to the motor (motor/drive belt). Start the treadmill at 3 or so and carefully apply pressure to the walking belt until it slips/stops. Watch the front roller. If it continues to spin when the walking belt stops, it's the walking belt. It the front roller stops with the walking belt, the motor belt is loose and needs adjusted or replaced.

To adjust the walking belt, locate 2 hex head bolts, one on either side of the deck on the very back of the machine. These bolts will be recessed inside the plastic covers. Your treadmill came with a tool for this, but if you can't find it, a standard (not metric) allen wrench kit will work. It's helpful to have a wrench in each bolt so that you can adjust them at the same time, but one will work.

The allen bolts thread directly through each side of the rear roller. As you tighten the bolts, it pulls the rear roller away from the front roller, tightening the walking belt. This also centers it; if you tighten one bolt, it pushes the belt towards the center of the walking deck away from the bolt you're tightening. So if the belt is too far to the right, tighten the right bolt and it will move towards the center.

Place your wrenches in the roller bolts and turn the machine on to 3-4 miles an hour. Keep your fingers clear of the belt, it will eat them. This method is quick, because you can see the belt move as you tighten one side or the other. It takes a few seconds, but if you tighten the right bolt for instance, you will see the belt move to the left. If the belt is loose but centered, tighten each bolt ½ turn and then get on the machine and see if it slips. The user manual will tell you to pull it up a couple of inches to test the tightness, which is a relative method and doesn't necessarily work. My wife can pull on the belt and get 2 inches, and I can probably get 3 or even 4 if I'm showing off. The best way to test it is to gradually tighten it until you can run on it without it slipping.

You should lube the belt a couple of times a year. You can get them from iconfitness.com

The above instructions is a generic one for this series. A slight adjustment might be required.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I need to replace the walking belt on a ProForm PFTL40070.


Installing An Icon Fitness Treadmill Belt You can save yourself a great deal of time by following these instructions as opposed to those of the manufacturer. Please contact us if you need any further help. UNPLUG THE TREADMILL BEFORE DOING ANY REPAIR!
Step #1- Remove the plastic railing on the right hand side of the deck. Most railings are stapled down so using a flat head screwdriver or another prying device is the easiest way to do it. The plastic is refastened using screws provided with the belt in a later step. If you cannot see the staples, you may need to remove the cosmetic center insert cover first by simply sliding it to the back of the treadmill. This rail is on the opposite side of the front roller pulley and motor. Some of the models aren’t stapled down and with these, you simply remove the rear end cap and slide the rail off the back of the treadmill.
Step #2- Loosen the rear roller and remove the two adjustment bolts. Some models have a spring loaded tensioner on the right hand side so be careful when removing these bolts. After the bolts have been removed, remove the rear roller end cap(s). The rear roller should now simply slide out of the walking belt.
Step #3- Remove the motor hood. Using a black permanent marker, make a mark on the front roller adjustment bolt on the motor compartment side at exactly where it fits flush with the roller so you will know where to retighten it later. The adjustment bolt is on the right hand side of the front roller. Then remove the bolt with a 7/16” wrench. Step #4- Remove the deck screws which should now be exposed since the plastic cover is off. In this step, also remove the staples with a pair of pliers. Be sure to remove all deck and staple debris before continuing.
Step #5- This step is easiest if you have another person to help but it is possible with one person. Lift up the side of the deck that has been loosened and making sure that the front roller is angled toward the deck, remove the old belt by simply pulling it to the side. A few models had a side hand rail that attaches to the side of the treadmill and if you have one of these, the hand rail must be removed first.
Step #6- Install the new belt just like you removed the old belt. Before proceeding, make sure that the belt is in the center of the two metal belt guides that protrude from the bottom of the deck. The guides should be angled where the sides of the belt are turned slightly upward. Sometimes these can get bent during installation so make sure they are contacting the edges of the belt or the belt will not stay centered properly. Step #7- Install the front roller adjustment bolt where you just start it. Do not return it to its original position yet.
Step #8- Install the deck screws.
Step #9- Slide the rear roller back into position and insert the end caps and rear roller bolts. Most models have a small ground wire on one of the rear roller bolts. Make sure to just slide this over the bolt before it is inserted in the roller. The ground wire dissipates static electricity that is built up on the walking belt to help the roller bearings last longer and reduce static discharge on the electronics.
Step #10- Adjust the front roller bolt to its original position.
Step #11- Tighten the rear roller bolts to where the tension on both sides feels even and you can lift the walking belt 2-3” in the center of the belt from the deck surface.
Step #12- Replace the right side railing with the screws provided using a screwdriver.
Step #13- Start the treadmill and align the belt according to the instructions in the owner’s manual or on our web site troubleshooting page under “Belt Centering Tensioning Instructions.”
Step #14- Once the belt is aligned, test the belt for slippage. If the belt slips at all, tighten the rear roller adjustment bolts equally on both sides ½ turn until the slippage is gone. Do not over tighten the belt where it has less than 2” of lift from the deck surface.
Step #15- Replace the motor hood and make sure no odd noise is apparent and that the belt is tracking and tensioned properly.

The treadmill is loose. How can this be fixed?


If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. Follow this procedure: First remove the key and UNPLUG THE POWER CORD. remove motor shroud, then find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability.
If your treadmill is not equipped with a bolt as described above, the drive belt must be tensioned by hand. While one person applied increased tension to the drive belt, the other person should tighten the motor set bolt Tighten the bolt and test. If the problem is not corrected, repeat steps above and retest.
If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. Follow this procedure:
First remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened. Rear Roller Adjustment Bolts


If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley and front roller must be replaced.
Follow this procedure: First remove the key and UNPLUG THE POWER CORD. remove motor shroud. Loosen the rear roller and remove the two adjustment bolts. Some models have a spring loaded tensioner on the right hand side so be careful when removing these bolts. After the bolts have been removed, remove the rear roller end cap(s). The rear roller should now simply slide out of the walking belt.

Instructions for changing the walking belt on my Cadence DX15 treadmill


1. Unplug the treadmill and remove the motor hood.

2. Use a permanent marker like a Sharpie and mark the roller positions on the bolt on the front roller and bolts on the rear roller- not all front rollers have this adjustment bolt.

3. Loosen the walking belt at the rear of the treadmill.

4. Remove the front roller adjustment bolt.

5. Some higher end treadmills use straddle covers that have an undermount or slide mount. If you don't see staples or bolts on the top of the cover, do not pry them up. If you do have one stapled or screwed down, use a flat head screwdriver or similar instrument, pop the plastic deck cover on the right hand side up (if you are standing on the treadmill like you are using it, the deck cover on the right side). If you see screws, simply unscrew and remove the screws. Screws are included to reattach the cover near the end of installation.

6. Remove the deck boltsmost have 3 or 4 bolts.

7. Once the deck is loose on the right side, completely remove the screws from the rear roller. Be careful with the plastic endcaps. The endcaps and the roller need to be removed in this step.

8. One person should hold the deck up and hold the front roller in position near the pulley while a second person removes the old walking belt (some models that do not fold and a very few number that do have a side handrail on the right side that attaches at the base of the treadmill…if yours does, remove this handrail before removing the belt). If you are talented, you can do this with a single person.

9. With one person holding the deck up and holding the front roller in position near the pulley, the second person should reinstall the new walking belt. Once the belt is in place, raise the deck up again and look underneath to make sure the belt is in the center of the belt guides that stick down from the deck underside. When tensioned, the belt guides should make the outside edges of the walking belt turn toward the center of the belt.

10. Replace the rear endcaps and rear roller and start the rear roller bolts. DO NOT TIGHTEN THE REAR ROLLER BOLTS IN THIS STEP.

11. Refasten the deck bolts. Go ahead and tighten the deck bolts fully in this step.

12. Refasten the front roller bolt and return it to the marked position (it was marked in step 2).

13. Replace if you have undermount straddle covers or fasten the plastic side deck cover with the enclosed screws if yours were screwed or stapled down. Removing the staples in the deck with a pair of pliers before reattaching the deck cover is not required but will make it easier to reattach.

14. Retighten the walking belt to the marked positions on the rear roller bolts.

15. Check the walking belt for proper tension by lifting it 2” to 3” in the center of the belt.

16. Test the treadmill for slippage and make adjustments (if needed) for lateral centering or tracking.

17. Once the belt tests good, replace the motor hood.

My belt keeps sliding to the left


The rollers in the front and rear need to be adjusted. If its sliding to the left, than the left side needs to be adjusted out until the belt stops going that way and stays on straight.
