How Do You Measure V belt size? Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin string to take this measurement and place it on a steel tape to get the correct length. Next, for “A” Belts (1/2” width) subtract two-inches from the outside measurement to select the correct V-belt.

What are the different types of V belts?
There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (ranked by their sizes 3V, 5V, and 8V), and light-duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L). The letter X classifies their counterpart cogged belt.
What do the numbers on a fan belt mean?
The first one, and the more recognizable one, is the manufacturer's part number, which is referenced when ordering the part. The second, and lesser known one, is a global industry standard number that indicates the size of the belt.

How to measure a V belt?
The easiest way is to use a specialized belt measuring tool, which hangs on a shop wall or can be placed on a counter, and features two jaws: one fixed and the other moveable. Put the belt in the fixed jaw of the tool with the V-section pointed downward and loop it around the moveable jaw. Push the moveable jaw downward until the belt goes from loose to tight and check the reading, which is usually found in the lower right or left corner.

What does the end point of a V belt mean?
The end point of the rotation will indicate the measurement of the belt. Keep in mind that wear and tear can cause V-belts to stretch out. So consult that list of common V-belt sizes and adjust accordingly if your measurement is not an exact match for one of the standard sizes.
Why do V belts squeal?
Among the various belts used in the operation of engines, V-belts are known for their solid traction and transfer of speed to components, as well as their long service life. Of course, no components last forever. If you notice a squealing noise, that could mean your V-belt is worn or cracked from years of use, causing it to slip from its grooves ...
What are the different types of V belts?
Remember that there are different types of V-belts, including: 1 FHP (Fractional Horsepower) belts, which are typically used in very low horsepower applications, such as fans. 2 A-E belts, which are used in medium horsepower machines and with single-belt and multi-belt drives. 3 AX, BX, CX belts, which are for medium and high horsepower industrial applications and single-belt and multi-belt drives. 4 3VX and 5VX belts, which are often used with high horsepower engine drives.
