Descriptions:* The outer fabric wrap is treated with high oil and heat resistance.* Specially designed with twisted neoprene rubber material, heat and chemical resistant.* The belt body is composed of high engineering synthetic rubber.Detail:* Name: V-belt* Model: A-82* Outer Circumference: 82" / 2083mm* Top Width: 1/2" /13mm* Height: 0.35" / 9mm* Material: Neoprene rubber* Color: BlackPackage:* 1 x V-beltHow to measure the V-belt?* Measure the length of the belt with an old V-belt1. Place a mark on the side of an old V-belt.2. Place the flat outer edge of the V-belt on a flat surface. Rotate the V-belt to place the paint mark against the flat surface. Draw a mark on the flat surface to designate the starting point of the measurement.3. Roll the V-belt along the flat surface until the paint mark returns to the flat surface. Place a second pencil mark on the flat surface to designate the point of contact of the paint mark with the flat surface. Measure the distance between the two pencil marks to determine the circumference of the V-belt.* Measuring the length of the belt without an existing V-belt1. Wrap a 1/4 inch nylon rope around both pulleys. Overlap 4 inches of the nylon rope.2. Draw a line across the nylon rope. Make sure the mark crosses both sections of overlapping nylon rope.3. Place the marked nylon rope on a flat surface. Measure the distance between the two marks with a tape measure to determine the required circumference of the V-belt.
