If you need an exact measurement, you can use the following formula:
How to measure a belt for a pulley. Next, we’ll take a measurement of the pitch diameter (p.d.), which is the diameter of the belt itself. Lastly, add all the measurements together. If we need to calculate the distance between the centres of the two pulleys, then we can use the following calculations to approximate this.
With a couple quick measurements you can plug the numbers into this formula to get your belt size! Belts are not measured by diameter nor folding the belt in half. The length of a synchronizing belt, also specifically referred to as the pitch length, can be determined by the total circumference of the band measured from the row of.
The first thing you should do is measure the pulleys outside diameter (o.d). The correct determines on your model/production year. For a given belt length, the distance between the pulley axles can be calculated using the above formula if the diameters of both pulleys are known.
Well get out the tape measure and the calculator. Measuring pulley width is relatively simple. D 1 = pitch diameter of larger pulley.
Push the moveable jaw downward until the belt goes from loose to. Harley davidson uses 1 ½”, 1 1/8”, 1” 20mm and 24 mm wide belts. Measure or find the diameter of the bigger pulley measure or find the diameter or radius of the another smaller pulley measure the.
The most accurate way to measure the circumference of a v belt is with a v belt measuring tool or using a cloth tape. First, measure the outside diameter (od) of the pulley. It's an approximation of the one given above:
