Replace walking belt - Nordic Track NordicTrack A2750 PRO Treadmill

if it's the walking belt, make sure that the rear roller is parallel to the back of the walking board. Sounds goofy, stand on the mill looking back away from the front of the display. Look down to where the walking belt goes around the roller, the roller should be parallel to the walking board.

Fit new belt ,check for slide adjuster slots.

Questions for analysis:

How old is this machine?
What is the condition of the walking belt and deck?
(most problems with treadmills cutting off during use stem from worn walking belts and decks - replacement is always recommended unless unit is less than 1 year old)

If you are able to walk on the edges of the walking belt (away from the center of the deck), run a test to determine if unit is still shutting off. If not this may be another indication of excess friction in the center (walking) area of the walking belt/deck. The only way to be accurate about this test would be to perform an amperage test, testing the machine unloaded, with load at 3mph, and with load walking on the edges of the walking belt

You need to replaced the walking belt and have a professional reset the drive belt to the proper tension.

Hello, There is no maintenace required. Some people like to oil the walk belt, The manual say to do this annually. To do this you loosen the walk belt and applty some synthetic oil to the walk board under the walk belt, then tighten the belt and the belt will distribute the oil where it needs to go. As far as the walk belt, just make sure that is stays in the center of the walk board. Now your front roller and drive belt. The roller does not get serviced, it has perminently sealed bearings. The drive belt usually lasts for many years, if you remove the motor hood and see alot of black dust, it will be the belt. At that point you need to see why it is comming apart/rubbing. After you determine that, you would want to replace it.

The slipping you are describing could be the drive belt slipping on the front roller or the drive pully on the front roller. To find out you need to remove the motor hood nad get on it and look. What you will be watching is the drive belt as it goes from the drive motor to the drive pully. When you try to stop the walk belt you will either stop the drive belt or stop the walk belt. If you stop both, the drive belt is at fault, if the motor keeps turning. If you stop the motor, the motor or the controller is bad. If you stop the walkbelt and not the drivebelt you have a bad drive pully on the front roller, and need to replace the front roller. When you do this you need to remove the drive belt, this is a ggod time to replace it.



Hope this helps, rate my solution if it helped you. Thanks, Matt

Either the walk belt is loose or the front roller pully has spun. In order to determine which one, you need to remove the moter cover and watch the drive belt and front roller while you walk, try to stop the belt and see which one stops. If the walk belt stops and the front drive roller keeps turning, then you need to put a couple of turns on the rear allen bolts. If the roller stops when the walk belt stops, see if the drive belt(small one going to the motor) stops as well. If the drive belt turns fine,but the walk belt and the front roller stop, you need to replace the front roller, because the plastic pully that is connected to the roller, is pressed on and cannot be tightened.

Unplug unit remove motor shroud then plug unit back in , press start and begin walking on the belt normally and try to stall the belt to make it slip ( planting foot to stop the belt).
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. Here is the procedure for adjusting the drive belt.
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.
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.
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 and test your treadmill for slipping. If belt continues to slip, and if their is too much tension ( you should be able comfortably twist the drive belt 90 degrees ) then replace drive belt. 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, here the procedure adjusting the walking belt.
If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller 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
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 front roller assembly will need to be replaced and the drive belt must be replaced also. 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.

If your belt is sticking there are 2 possible causes. Either the walking belt itself is loose or the drive belt. The way to check is look at the front roller when you step on the walking belt. If the walking belt stops, but the front roller continues to spin, the walking belt is loose and needs tightened. If the front roller stops when you step on the walking belt, then the drive belt needs tightened or replaced. The walking belt can be tightened fairly easily, there are bolts at the rear of the machine that adjust the rear roller. The drive belt is a little more involved and requires removing the motor hood. Check to see what the front roller is doing and I'll help you further.
