Pulley belts, also known equally V-belts, are safe belts wrapped effectually a set of pulleys that transmit force equally an engine rotates the pulleys. In gild to supersede or install the proper belt for your pulleys, you lot need to take an accurate measurement of the length so you can cull the right i. Fortunately, measuring a caster belt size is like shooting fish in a barrel to practice. If you already have a chugalug that you need to measure, you can employ a flexible measuring tape or read the chugalug codes. If you don't have an existing chugalug to measure, you tin can use the pulleys themselves to find the right size.

1. 1

   Mark a line beyond the belt with a white marker. Agree the belt in i hand and take a white marker or a piece of chalk and mark a line on the exterior of it. Brand the line all the way across the width of the belt.^[one]

   • Make certain the line is thick enough to be visible and won't rub off as well hands while you're measuring.

2. two

   Line up a measuring tape with the line on the belt. Apply a flexible record measure out so you can wrap information technology effectually the surface of the belt. Line up the stop of the tape where the measurements begin with the line you marked on the belt.^[2]

   • Make sure the marker is lined up exactly where the measurements begin, rather than with any metal clasp or plastic that may be on the terminate of the measuring tape.

3. three

   Wrap the measuring tape effectually the belt until information technology meets the marker. Use ane hand to concord the tape measure in identify while you wrap information technology around the chugalug. Keep information technology flush with the surface of the belt and brand sure there aren't any folds or creases that could bear upon your measurement. Continue wrapping the tape mensurate until it meets the other end.^[iii]

   • Keep tension on the measuring record so your measurements are accurate.

   Alternative: You can also use a long ruler or a steel record measure to measure the caster belt by lining up the mark with the outset of the ruler or tape measure, and then rolling the belt until the line comes back to its original position. However, this method may not exist as precise.

4. 4

   Concur your finger where the tape meets the mark and notation the distance. In one case you've wrapped the measuring tape around the belt, apply your index finger to mark where they meet and then remove it. The point where they meet is the size of the pulley belt.^[4]

   • You can make a mark on the measuring tape or write down the measurements then yous have them for future reference.

   Tip: If your pulley belt is old or worn, it may accept stretched a pocket-sized corporeality. If yous programme to replace it, choose a belt that is about 0.5 inches (ane.iii cm) smaller than your measurement so it fits snugly onto the pulleys.

1. one

   Employ string if the belt is on the caster or if in that location is no chugalug. If you're trying to notice the size of a belt that is connected to pulleys without removing it, use a roughly 4 ft (1.2 m) long piece of string. Yous can too employ string to find the belt size using the pulleys themselves if in that location is no belt.^[5]

   Tip: You tin employ either string or rope to detect the belt size using the pulleys, just if you have a rope that's the approximate thickness of the grooves in the pulleys, it will be easier to agree in place while you measure out.

2. 2

   Hold 1 cease of the string on meridian of the belt or ane of the pulleys. Have the cease of the string and choose a caster to place information technology on top of. Use i paw to hold the string in place so it doesn't movement when you take your measurements.^[vi]

   • It doesn't matter which pulley you choose, whether you have a belt attached to it or not.

3. three

   Wrap the cord effectually the pulleys until information technology meets the other end. Keeping the terminate of the string held against the pulley, bring the string around the other pulley until it meets it. Maintain tension on the string so its taut.^[vii]

   • Use your hand to hold the string so it's continued to the terminate.

4. 4

   Mark the string where it meets the other end and remove it. Employ a marking to brand a line on the string where information technology meets the end on the pulley. And then, take the string off of the pulleys.^[eight]

   • Make sure the marking is visible on the string.

5. 5

   Lay the string flat and measure the distance between the end and the mark. Place the string on a apartment, even surface and stretch it out so it'due south straight and taut. Use a ruler or tape measure out to measure the distance from the stop of the cord to the mark you made to find the size of the caster chugalug.^[9]

1. i

   Inspect the surface of the belt to look for a lawmaking printed on information technology. If yous have the chugalug that yous need to measure, bank check the outer surface for a lawmaking printed in white letters. Look for a series of messages and numbers that are repeated in multiple locations along the belt.^[ten]

   • If you don't have a chugalug to measure, you'll need to use the pulleys to determine the chugalug size.
   • If the belt is actually worn, you may not be able to meet the code printed on the surface. If that's the case, you'll need to measure the belt itself.

2. 2

   Look for an A, B, C, D, or E in front end of the code to place a classical belt. A classical belt is the most common blazon of pulley belt and uses the letters A-Due east in the prefix to place a specific top width and depth. Classical chugalug codes are designated by the within circumference. And then to find the caster belt length, you need to add the width of the belt to the circumference measurement designated in the belt code.^[xi]

   • If you're replacing your pulley belt, choose a replacement that has the same prefix so you know information technology fits the pulleys.

   Classical chugalug measurement tips:

   Add 2 inches (5.ane cm) to an A prefix, three inches (7.six cm) to a B prefix, 4 inches (10 cm) to a C prefix, 5 inches (xiii cm) to a D prefix, and half dozen inches (fifteen cm) to an E prefix. For case, if the belt has a lawmaking similar A34, so the exterior circumference of the belt is 36 inches (91 cm).

3. 3

   Identify an FHP chugalug by a 3L, 4L, or 5L prefix on the code. Partial horsepower belts, or FHP belts, are often found in appliances and small machines. Await for the prefix that identifies an FHP belt in the chugalug code. FHP belt codes designate the outside circumference measurement of the chugalug. To detect the length of the belt, use the number following the FHP chugalug prefix.^[12]

   • For instance, if the belt code reads, "4L360," and then the belt is 36 inches (91 cm) long.
   • Choose a replacement FHP with the aforementioned prefix and then it fits the pulleys properly.

4. 4

   Detect a 3V, 5V, or 8V prefix to identify a Deep V-belt. Deep V, as well known as narrow belts, are thicker than classical belts and are oftentimes used in compact drives. Their codes identify the outer circumference of the chugalug, so to observe the length, expect for the number that follows the prefix for an authentic measurement.^[13]

   • For example, if the lawmaking on the belt looks like, "5V280," so the belt length is 28 inches (71 cm).
   • Cull a belt with the same prefix if y'all programme to replace your Deep 5-chugalug.

• If you're measuring the size of a caster belt past using the pulleys themselves, try using a rope that fits into the grooves on the pulley and then you can have a more accurate measurement.

• Use your measurements to assistance you lot cull the proper replacement chugalug if your electric current belt is frayed or damaged.
