I am having a difficult time finding a replacement walking belt for a NordicTrack A2750 pro. I have gone to the website but this particular belt does not seem to be listed (or I am just missing it). Help!

sounds like the belt is loose.there are bolts at the back on either side that tighten or loosen the belt.adjust with belt running about 3mph. tighten both bolts about 1/4 turn each while watching the belt to make sure it is centered. give it about 15 seconds after you tighten to see the adjustment that u make.the walking belt should only be able to lift up a little bit like 1 inch. you shouldn't be able to get ur hand all the way under belt (not running of course).

see the video and proceed according. God bless you

Did you ever figure out an answer to this? Mine is doing the same thing

If you have tightened the belt and it continues to slip it is usually a sign that the deck and belt are worn. You may be looking at repairs that might be more costly than getting a new machine. You can check the deck by sliding your hand under the belt (not running) and feeling the deck surface. If you feel grooves or any rough spots then you need to replace it. The underside of the walking belt will also feel fuzzy like a peach if the fibers are breaking down.
If the machine is not very old or hasnt had much use then it could be several other things causing the slipping/stopping of the belt.

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.

It sounds like you have a bad bearing. If you are not familiar with repairing/replacing bearings on a treadmill, I suggest you contact NordicTrak and have a tech come out and repair it.

Is it slipping side-to-side or front-to-back? If side to side, you can stop this by adjusting the two allen bolts on the bottom fronts sides of the treadmill. If it is front to front, and your treadmill is more than a few years old, the belt is probably stretched and needs replacing.

You can get a quote for a new belt at treadmill parts

you will need to attach star washers to the rear roller bolts, they are having an issue with the lock washers they put on the rear roller bolts. Replace them with star washers. Tighten belt until it can be lifted about 2"-3" in the center.

If the walking belt is off-center, remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left idler roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise 1/2 of a turn. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is centered
