How to Tighten the Belt on a Nordic Track

After continuous long-term use, the belt of a NordicTrack treadmill can lose tension. A belt that's too loose raises the risk of damage to the belt or the machine itself. Check the belt once a week. If the belt can be lifted more than 5 inches off the platform, then it needs to be tightened. It takes only a few minutes to tighten the belt on a NordicTrack treadmill, but doing so can greatly prolong the life of your machine.

Two-Adjustment Bolt Style

Step 1

Look at the rear roller of the treadmill to determine whether it is a two-adjustment bolt style. If there is a head that takes an Allen wrench, it is a two-adjustment bolt style. (If not, skip to the next section) This style of treadmill requires you to adjust two different bolts.

Step 2

Unplug the treadmill and remove the safety key to ensure the treadmill will not accidentally be turned on.

Step 3

Insert an Allen wrench into the bolt on one side of the rear roller. Turn it clockwise one quarter-turn to tighten it. Locate the bolt on the other side of the rear roller and do the same.

Step 4

Pull up on both sides of the belt to check the height. The belt should come up 3 to 4 inches from the platform. Both sides of the belt should be at an equal height.

Step 5

Tighten or loosen the bolts until the belt is at the proper tension. To loosen the belt, just turn the bolts counter-clockwise.

One-adjustment Bolt Style

Step 6

Look at the bolt on the rear right roller. If it has a hex head and a nut located at the end, then you have a one-adjustment bolt style. This style requires you to adjust only one bolt.

Step 7

Unplug the treadmill. Remove the safety key if the treadmill has one.

Step 8

Put a wrench on the nut at the end of the bolt to hold it in place. Place a second wrench on the head of the bolt. Turn the bolt clockwise a half-turn to tighten the belt.

Step 9

Check the height of the belt to make sure it comes 3 to 4 inches up from the platform. Tighten the bolt further if necessary. If it needs to be loosened, turn the bolt counter-clockwise.
