Bowflex TC5000 L5 Belt will not move antmore.


Dear Sir:

Hello , I hope everything is fine with your family.

Thank you by your request, and I will help you inmediately.

You have a Mechanical problem, please do the following:


Please do this with carefully!

The motor drive belt is adjusted independently from the walking belt. Some newer models have an auto tensioner which is a lever that has a wheel that puts pressure on the drive belt and a spring on the other end that automatically loads the belt to the proper tension. You should not adjust these since they are preset.

Tension can be affected slightly by adjusting the tension of the walking belt but if you have a slipping problem, the drive belt will require replacement. If your drive belt is too loose, it will slip on the front roller pulley or the motor pulley. If it is too tight, it will increase your amp draw to the point that you may have an electronics or motor problem. Due to this, it is better to be on the safe side and replace a drive belt rather than risk over tightening it. A drive belt is usually $29.99 or less while many parts you can damage by over tightening can be more than $300.

Additionally, too much tension can cause bearing failure in the motor and the front roller and front roller pulley failure. It is better to having the belt a little too tight rather than too loose due to the possibility of injury if the belt slips.

Motor Belt Adjustment- Icon Units

DO NOT REMOVE ANY OF THE MOUNTING BOLTS TO THE MOTOR. SOME MODELS WILL REQUIRE 2 9/16" WRENCHES AND MAY REQUIRE TWO PEOPLE TO ACCOMPLISH THE REPAIRS

Before beginning this repair: Check to make certain that the drive belt requires adjustment. Check out belt slipping instructions or with the motor cover removed, walk on the belt normally and try to stallthe belt to make it slip.
Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. 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. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley.

Step 1- 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. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust.

Step 2- Find the set bolt(s) on the motor. This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting. Loosen this bolt(s) but do not remove. Jack bolt models will have flat mounts and may contain up to four bolts.

Step 3- Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with this bolt, skip to Step 4. If your treadmill is equipped with this bolt (very few are) the repair will only require one person. Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts from Steps 1 and 2 and test your treadmill for slipping. If belt continues to slip, repeat Steps 1, 2, & 3. If a second attempt does not repair the problem, skip to Step 5.

Step 4-
If your treadmill is not equipped with a bolt as described in Step 3, 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(s) that are described in Step 2. Tighten the bolt from Step 1 and test. If the problem is not corrected, repeat Steps 1, 2, & 4 and retest. If problem persists, skip to Step 5.

Step 5-
If you have arrived at this step, let's make sure you have a drive belt tension problem. With the motor cover removed, walk on the belt normally and try to stall the belt to make it slip. Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. 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. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley. If this is the problem, you will notice it because the plastic will usually make a loud squealing sound on the metal front roller. The entire front roller assembly repaired or replaced (see the help topic on replacing a pulley) and the drive belt must be replaced. We suggest replacing the drive belt as well because it is a low cost item and will most likely, have suffered unusual wear from the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced.

Step 6- The belt should be able to be turned by hand at approximately a 90 degree angle from its normal operating position.


Thank you in advance, sincerely. God bless you.

Belt runs with hesitation. stops during rotation and starts again. like it's slipping


If it does this while you are exercising it is one of two problems. First make sure that the walk belt is adjusted correctly( you should be able to pick up the outer edge of belt about 1.5 inches), if the belt is tight enough, then remove the front cover ( 3 screws at fron and 2 or 3 under), start the treadmill with cover off and watch as you walk, see if the drive belt(small one going from motor to front roller),is still turning after you try to STOP the walk belt with your feet. If the drive belt still turns, see if the front roller stops but the drive pully (other end of drive belt)still turns. If so you need a front drive roller assy. Od if the belt(drive) quits while the motor stays running, adjust the motor, or replace the drive belt.

Track sliping


Adjust walking belt tension at the front of the unit using the provided hex wrench on the exposed adjustment bolts located on each side of each front roller. Be sure to adjust both bolts on each roller the same amount as to not disrupt belt alignment. Tighten (turn clockwise) each adjustment bolt in full turn increments. After each adjustment, restart unit and check to see if belt slippage has been eliminated. Repeat if necessary.If slipping feel persists after several adjustments, stop and see if it maybe the drive belt. Remove left rear plastic cover to expose “v” belt drive line and motor. Tighten nut on the motor tension bolt located on front side of motor in 1/2 turn increments until drive belt slippage is eliminated - DO NOT OVER TIGHTEN. Replace cover when finished.

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

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

Belt stops running while standing on the treadmill


Either front roller may need to be replaced or the motor drive belt may need to be adjusted. This problems are caused when a walking belt is worn out and in need of replacement. Too much tension can cause bearing failure in the motor and the front roller and front roller pulley failure.

Motor drive belt adjustment: The motor drive belt is adjusted independently from the walking belt. Some newer models have an auto tensioner which is a lever that has a wheel that puts pressure on the drive belt and a spring on the other end that automatically loads the belt to the proper tension. You should not adjust these since they are preset. Tension can be affected slightly by adjusting the tension of the walking belt but if you have a slipping problem, the drive belt will require replacement. If your drive belt is too loose, it will slip on the front roller pulley or the motor pulley. If it is too tight, it will increase your amp draw to the point that you may have an electronics or motor problem. Due to this, it is better to be on the safe side and replace a drive belt rather than risk over tightening it.

How to remove and replace a motor belt on proform


Hello there. To replace the drive belt (motor belt) follow this procedure.
1)Remove power to the machine
2)remove the hood cover (3 screws on the rear of the cover)
3) loosen the adjusting bolts for the walk belt located on the opposite end of the walk belt from the hood assembly. Loosen the adjusting bolts 10 full revolutions. This will loosen the walk belt.
4) You should then walk the drive belt off of the front roller/pulley assembly by pushing the belt to one side while turning the motor. If you are nable to do this you will need to loosen the 2 bolts holding the drive motor in place.
5) After removing the drive belt you can then slide the drive roller to the side out of the frame and it will slide out the other side of the bracket. This will allow the belt to be removed from the front roller and be replaced.
If you had to loosen the bolts holding the motor you will need to retension the drive belt by pulling the drive motor back while tightening the bolts. This will require another person to help tension while you tighten the bolts.
You can then retension the walk belt using the adjusting bolts and retightening them 10 revolutions.
Good Luck Tim
