I need to replace the motor belt but i can't remove the front roller of my H140t Healthrider treadmill

If we use the treadmill daily it might need maintenance regularly. Running of 180 hours on the treadmill might lose the belt. Drive belts usually last for longer time of 5 to 7 years.So you have to adjust the tension of the belt.
Keep enough tension in the drive belt
If a user wants to improve the motor efficiency it is necessary to connect the motor to the front wheel which helps the belt to spin.
Too little tension results in slippage, excess heat and high-pitched noise, or too tight belt produces tension causing stress on belts, bearings, and shafts. Prevent premature motor failure by adjusting the belt at a suitable place. The belt should be fixed half an inch of play.
To improve the efficiency of the motor align the belt properly and lubricate it on time. Keep in mind such useful options may help the user. When the belt slips off the track, the friction between the belt and drive pulleys causes the belt to overheat. If you hear a high-pitched noise, it's time to replace the belt with a new one.
How to Ascertain that the drive belt can still be used?
If you test Front-wheel by walking on the treadmill and the belt stops but the motor is still moving, It means that the drive belt is loose and needed to be tightened or replaced.
Keep in mind
There are some exercises that are not suitable for the treadmill like jumping on it. This kind of usage can be rough on your treadmill and lead to your treadmill belt slipping.

Check the front roller. Remove the drive belt and run the motor. If the noise is not there replace front roller.

1) replace the batteries with a new ones and the same type and the correct polaritires.
2) clean the contacts batteries with c. cleaner and retight the springs with a plier.
3) tight and clean the ribbon cable for keypads.
4) adjust the REED swtich,very well, clean it, and tight the
connector very well.
God bless you

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.

1) Lube the deck belt, this produce enough friction between deck vs deck belt, and shut down for to protect the electronic system
2) lube the rollers bearing very well.
3) Test the drive belt and replace
4) Test the motor input voltage, if there are the motor need repair.
5) test the output voltage board, for input voltage motor, if there are not the board is faulty.

This is really tricky job. If you don't want to damage anything it may be wise to call a repairer. It won't cost much ,but worth it.

Hello, It sounds like you have aslipping front roller pully. Remove the motor hood and watch the front roller while you are on it. Once the belt is moving slowly, try to stop the wlak belt by planting your fett for a second, if the walk belt stops, but the drive belt and motor continue to run, the plastic pully is slipping and the whole front roller will need to be replaced.

Hope this answers your question.

hi it seem like the motor is fine but the belt on the motor either needs to be tightened or replaced. best way to find out is to take off the front cover showing the motor and step on the treadmill. if the belt isnt moving but the motor is spinning then you need to replace the belt on the motor. or you can try to adjust the belt. i had the same problem, i just tightened the belt and everything works fine.

you can purchase a new roller from fitnessrepairparts.com or treadmilldoctor.com it needs replaced. The plastic is what keeps the belt in place.

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.
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. then remove front roller and replace with new reverse procedure mentioned above
