How To Read V-Belt Numbers. Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2" less for a 4L belt, and 1-1/2" less for a 3L belt. An example would be 4L460, which would be 46" long outside, 44" inside.

Once you have determined the length of the belt you require use the diagram to the right to determine the section.

Available in 3LK, 4LK, 5LK, AK, BK, reference charts above for dimensions.

The fractional horsepower V-belt profile is designed for light-duty applications such as lawnmowers, snow blowers, attic or furnace fans, etc. These belts have a thinner cross-section and lighter gauge tensile cord (Figure 6), making them more flexible and able to bend around small sheaves. Figure 6 — Fractional Horsepower V-belt Profiles

Next, you need to measure the length of the belt. Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin
