You should not adjustthese since they are preset. Tension can be affectedslightly by adjusting the tension of the walking belt but if you have a slippingproblem, the drive belt will require replacement. If yourdrive belt is too loose, it will slip on the front roller pulley or the motorpulley. If it is too tight, it will increase your amp draw to the point thatyou may have an electronics or motor problem. Due to this, it is better to beon the safe side and replace a drive belt rather than riskover tightening it. A drive belt is usually $29.99 or less while many parts youcan damage by over tightening can be more than $300.Additionally, too much tension can cause bearing failure in the motor and thefront roller and front roller pulley failure. It is better to err onhaving the belt a little too tight rather than too loose due to the possibilityof injury if the belt slips.

Dear Sir:

Hello, I will try to help you, inmediately.

Please follow the next step:

1) 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.

2) 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, . 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 If a second attempt does not repair the problem

3) 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.

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.

Take the motor hood off and set aside. Straddle the walk belt and set the speed to 3 or 4. Take one foot and step on the walkbelt hard. While doing this look at the pulley on the front roller. Does just the roller stop and the pulley keeps turning, does the roller and the pulley stop together or does just the walkbelt stop? If the walkbelt is the only thing to stop it is loose. If the pulley, roller and the walkbelt stop the motor belt is loose. If the pulley continues to turn and the roller and walkbelt stop your pulley is slipping on the front roller ( press fit). Two solutions: 1) replace the front roller or 2) pin the front roller to the pulley. Align the pulley roller to the motor pulley by tapping it into position. remove motor belt by loosing motor. Drill 1/8 hole through the pulley and roller. Take a larger drill bit and countersink the pulley hole so the head of a screw will be below the pulley grooves when installed. install the screw. If you mess it up -- turn the pulley and roller and try again. This is a permanent fix for this problem. You may have a little pulley wobble and that is OK.

Pull the hood off. Stand on the sides of the walk platform and start the belt at 4mph. Take one foot and step on the walk belt hard. Look at the pulley on the front roller. Does the pulley continue to turn while the roller stops? If so, the pulley is slipping in the roller (which is a press fit). Replace the front roller or remove the motor belt from the pulley.Align the pulley with the pulley on the motor by tapping with a mallet. Drill an 1/8 hole throught the pulley and roller. Countersink the pulley hole so a small head screw will be under the pulley groves. Install screw in this hole. This is called pinning and is a pemanent fix. If both the pulley and the roller stop together when the belt is stepped on the motor belt is loose. If only the walkbelt stops when stepped on, the walkbelt is loose.

The pulley on the front roller is pressed on. Sounds like you pulley has broken free from roller. The front roller needs to be replaced. A quick fix which I've seen last a long time. First verify that this is what your problem is. If it isn't obvious mark roller and pulley, use machine and see if your mark moved. Sounds like yours should pretty easy to tell. If it is indeed lose, mark where pulley sits on the roller. Remove the drive belt. Take a hammer and gently bump pulley to the side. Apply some super glue where pulley normally sits. Bump pulley back into place and let dry. Replace drive belt and check.
