How do you change a belt on an air compressor?

How do you change a belt on an air compressor?

A: Follow few steps given below:

  • Disconnect the power to the air compressor.
  • Drain the air compressor tank by opening the drain valve.
  • Remove the belt from the pulleys.
  • Install the new belt around the pulleys.
  • Tighten the belt by moving the motor mount toward the pump.
  • Reconnect the power to the air compressor.


How tight should my air compressor belt be?

A: The belt on your air compressor should be tight enough so that there is no slack, but not so tight that it puts undue strain on the motor or other parts of the system. You should be able to depress the belt about halfway between the pulleys with moderate pressure.

How do you check a compressor belt?

A: With the power to the compressor turned off, spin each pulley by hand. The belt should track straight and not slip on either pulley. If the belt is damaged or worn, it will need to be replaced. Check the condition of the pulleys as well – if they are damaged, they will need to be replaced before installing a new belt.

How do you measure an air compressor belt?

A: You will need to know the circumference of both the drive pulley and the driven pulley in order to properly size a replacement belt. To measure the circumference of a pulley, wrap a measuring tape around the center of the pulley (not the edge) and note the measurement. Alternatively, you can use a length of string or rope to wrap around the pulley and then measure the length of string or rope required to go around the pulley once. This measurement can then be converted to inches or centimeters to find the circumference of the pulley. Once you have the measurements of both pulleys, you can use a belt size chart to find a replacement belt that will fit your compressor.
