How to Replace Belt from Air Compressor And about it?

Now days, air compressor size is getting smaller. So, it is not easy to replace the belt of air compressor. And it will make you to use your money to call a technician to replace it. That’s why we are going to give you detailed information about air compressor reviews. Even so, the process is still pretty straightforward and can be accomplished quickly with a minimum of effort.


Materials Required

  • Wrench or socket set
  • Replacement belt


  1. Remove the belt guard. The safety housing around the belt and pulleys is usually bolted to the base and reinforced by one or more brackets. To remove it, first loosen the bolts holding it to the base and remove any attached support brackets.
  2. Remove the old belt. If it has snapped entirely in two it is easy to remove. If it is just frayed or worn you will need to loosen the motor from the base and slide it toward the compressor to get the belt free.
  3. Determine the replacement belt size your compressor needs. If the belt isn’t broken it will be easier to determine the best belt replacement size. Some auto supply stores have belt measuring devices that tell you the size.
  4. If your belt is broken, it is more difficult to determine the precise size. You might need to look at the owner’s manual or manufacturer’s website to determine the proper size belt for your compressor.
  5. Install the new belt on your compressor by placing it over the motor pulley and compressor pulley. The screws holding the motor should be loose, and the motor should be slid as close to the compressor as the slots will allow. If the belt is too tight, do not try to force it. You might cut the inside of the belt, causing it to thump with every turn and quickly break again.
  6. Slide the motor away from the compressor to tighten the belt. You might need a block of wood or an assistant to help hold it taught while you tighten the bolts that hold the motor.
  7. Test the tension of the belt by pressing down in the center between the two pulleys. The belt should be able to be depressed about 1/2 inch. If it is too tight it can burn out the bearings on the motor or compressor. If it is too loose the belt might slip and wear out, or not turn the compressor.
  8. Replace the belt guard, support brackets and attaching bolts. Make sure they are all tight. Air compressors experience a lot of vibration that can cause screws to loosen if not tightened properly. Plug in your compressor and the job is finished.

About Air Compressors

Though we may not be aware of the fact, compressed air is everywhere. The most common type of air compressor that we see is the type that pumps air into our tires at the gas station.
There are a few different types of air compressors, though most of us probably don’t know what they do or who uses them.


There are a variety of air compressors available on the market today. They include: rotary screw, reciprocating piston, vane and portable. Though they may differ in size and shape, all air compressors are built to do the same things. They compress free air.


The air compressors most commonly seen by people are the reciprocating compressor. They are also known as “work horse” air compressors because they are used in a variety of places for a variety of reasons. You usually see these compressors on hardware store shelves, at the corner gas station, at car garages, in home basements and in residential garages.


Air compressors are used for a variety of reasons and can be used for much more than just tire inflation. These tools can also power wrenches, nail guns and spray guns.

Running tools off of air compressors is an easy way to make sure that your tools have enough power and force to complete the task at hand. In fact, tire stores typically use air compressors to power the tools they use to remove the lug nuts from tires. When replacing the lug nuts, one can be sure that they will be tight enough because of the force created by the air compressor, as opposed to hand-tightening the lug nuts.
