How To Adjust A Treadmill Belt

How To Adjust A Treadmill Belt?


A treadmill is a machine that assists people to continue their outdoor workouts at home. As it is a machine, some anomalies can occur due to continuous workouts.

The machine uses a belt as a power transmission technique and hence, the belt can get loose after a certain period. It is necessary to observe the gap between the belt and the board.

If the gap becomes narrow and the belt and board are getting closer then the belt seems to be loosened. As the belt is a major component of the machine, rapid and effective action is needed to overcome the drawbacks. Adjusting the belt is quite easy and simple.

There are two methods of adjusting a belt. The methods are briefly described below.

Method 1. Fixing By Keeping The Machine On


There are several steps to follow one by one to get the expected result.

Step 1: It is essential to find the required screws to adjust the belt properly. In most of the machines, the screws are located near the roller axis and locked towards the back. Hex screw is commonly used to set treadmills. Hex screws have a six-sided head which requires a special type of tool named Allen Wrench to fix. The hex key is also capable of adjusting the hex screw.

Step 2: You need to turn the treadmill on to adjust the belt. A speed of 3 miles (5 kilometers) is optimum to adjust the belt.

Step 3: After the first two steps, here comes step 3 which is the most important step. You need to turn the screw in a clockwise direction if the belt needs loosening and for tightening you need to turn the screw towards the counterclockwise direction. There are some important notations to be followed.

  • Not more than a quarter turn on each time.
  • Adjust every single screw with a same number of turns.
  • Tight the right screw if the belt needs centering towards the right.
  • Tight the left screw if the belt needs centering towards the left.

Step 4: It is necessary to continue the adjusting work till the belt reaches the center and does not slip. It is also important to make sure whether the belt is centered between the two boards and tight enough to prevent slip.

Method 1. Fixing By Keeping The Machine Off


Step 1: The first and the most important step is to turn the treadmill off and unplug it from the socket.

Step 2: To fix the belt, you need to find the screws that are adjacent to the belt. These are often located towards the back next to the roller axis. Most of the time treadmill is adjusted using a hex screw that requires an Allen Wrench to fix.

Step 3: The screw needs to adjust either to the left or right depending on whether it needs to tighten or loosen. There are some important notations as well which are like the first method.

Step 4: After adjusting, turn the treadmill on and have a check whether it needs more adjustment or not.

Step 5: It is necessary to get going until you reach the final destination. The belt should be located to the center and tight enough to prevent slip. It is important to turn the treadmill off and unplug it every time.
