How to Measure a V-Belt
- Determine Belt Type: Look at the markings or compare to a standard chart.
- Measure the Width & Thickness: Use a caliper to measure the top width and thickness.
- Measure Belt Length:
- Inside Diameter (ID): Measure the inner circumference if the belt is still in one piece.
- Outside Diameter (OD): Use a flexible tape to measure around the belt’s outer surface.
- Effective Length: The working length, depending on pulley size.
