Belt Installation and Tension Procedure
When you install a new drive belt, the belt will increase in length when it first operates. Do this
procedure again after 24, 80, and 160 hours of operation to get the correct tension.
1. Remove electrical power from the machine. Refer to applicable safety codes.
2. Install the belt loose on the pulleys, or make the belt loose, if it is tight.
3. Measure the outer diameter of the belt accurately. If this is not the first time that you did this
procedure, the belt will be longer this time.
4. Calculate the correct length of the belt when it is tight, as follows:
• If you installed a new belt this day, multiply the length by 1.003. This gives the necessary
length when you make a new belt tight.
Example: 152 inches (3861 millimeters) x 1.003 = 152.46 inches
(3872 millimeters)
• If the belt is not new (operated), multiply the length by 1.005. This gives the necessary
length when you make an operated belt tight.
Example: 152.2 inches (3866 millimeters) x 1.005 = 152.96 inches
(3885 millimeters)
5. Make a loop of the correct length with flexible wire. Attach the ends together tightly.
6. Put the wire loop around the belt.
7. Make the belt tight un,truetil there is no play in the wire loop.
