Thanks for watching. The belt thickness should be close however you might get some variation between manufacturers and there might be some warping over time with heavy use. The width and length is needed for matching.

2:40 So if a belt happens to be classified as a "classical" belt, then it's measured by the inside circumference rather than the outside, as is done for the FHP and deep Vee belts? That seems like a recipe for confusion... How do you know for sure if it's classical vs FHP? Are the size profiles unique in each type?
For the A belt with the 5/16" height, the calculation of 2*Pi*(5/16) is 1.96, which matches the -2 Delta of inside and outside circumference, but the C belt with 17/32" height is only 3.34", not a Delta of -4". Are those just supposed to be approximations for estimating the inside belt size based on the outside circumference measurement, rather than some exact cross-reference? These are the exact Delta values based on calculations: A 1.96" B 2.55" C 3.338" D 4.712" E 5.694" The C belt is only one that rounds off to a different number than the guidelines given; the other ones seem okay.

(For that particular belt thickness) It would have been good if they stuck to one method; I guess the classical inside method was first, and the FHP came later, and became the preferred measurement.
Thanks for watching. A K belt will just be a specialty belt for the drill press.

@AmreSupply Thanks for the reply. However, I'm wondering also another thing. Let's say I have 3 pulley diameter options and the one with bigger diameter has faster than other 2 pulleys. Can I say it's the optimum velocity between these 3 pulleys? I'd really appreciate it

Does a B belt have more grip--less slippage--than an A belt? I have a wood splitter that slips on the pump pulley with a difficult split using an A belt and I'm wondering if changing to a B belt will improve the grip significantly.
Hi Don, thank you for watching. Overall its best to match the belt width to the intended design. Having an ideal tension (tight but not too tight) and a clean belt will help prevent slippage. If you're curious to learn more this video did a great job explaining how to address slippage. th-cam.com/video/syWiGYDOM70/w-d-xo.html
Great video!!! But i want to buy a belt for my lawn mower. They sais it is a 5/8 belt by 84 inch. But it said "B" and "5L" on the packaging. So it is not really a 5/8? A 5/8 is a 5v belt right?
Thank you, we're glad that you found it helpful! As you can see at 3:48 belts that are 4L will be the same as A. Belts that are 5L are also a B. The width on the B & 5L is 21/32 which is very close to 5/8 (which would be 20/32). So in this case 1/32" difference in width will not matter.
Thanks for watching. To find a matching belt you can enter your model number for your washing machine into this tool: www.amresupply.com/lookuppart Or match based on outside circumference as M belts are designated by outside length.
Sir,i am from India i have a wet grinder and that belt is broken difficult to find the same the belt number is poly V belt 4PJ 745 so what is the alternative i can buy please help me
I’m looking at a pulley that says it accommodates “1/2” ABS belt style.” Does anyone know if that 1/2 inch would be referencing the top width, or the depth of the belt? Thx
Thanks for watching. If it only lists one number than that will be for the top width. You can see here on our website that Deep V belts are listed by top width as the main way of sorting: www.amresupply.com/catalog/3V-Deep-Wedge-V-Belts-HR2G
I am trying to find a Gates Truflex 4LXA720 belt but cannot find it anywhere. Where can I get a similar belt and what size do I need based on the markings?
Thanks for watching. From the number it seems like it is a 4L with a length of 720. If the belt is cogged you'll want to match that. There can be some variation in how these are numbered and what extra letters and numbers are added depending on the application. In any case you can still doublecheck and measure the belt.
Thanks for the video. Any idea what code "O-560" means? The number "29" also appears on the belt, about 1.5" away from the "O-560". It's a belt off of a cheap, imported drill press. The measurements are: 3/8" wide x 1/4" deep x 24" outside diameter.
Thank you for watching! It seems like the O-560 code is likely a manufactures internal number rather than a standard code, it doesn't line up with any codes or measurements that we know of. If you found another belt with a O-560 code or designation, it will likely be a direct replacement.
I know I'm late but better than never. There is, indeed, an O type V belt. At least my drill press from Taiwan is using this type of belt. Just like A, B, C, D... The number next to the designated letter is the inner length (millimeter). You can search for O type V belt on AliExpress.
Hi, can I use a A series belt to replace an 4L-340 belt? May I also know what exact code should I be looking for an A type of belt? I would use it on my old washing machine. I would be grateful if I get a free answer from you. TIA
Thanks for watching. If you have a 4L-340 belt that measures 34 inches from the outside circumference, then the matching A belt will be also have an outside circumference of 34, subtract 2 (as mentioned at 2:57) and you get an inside measurement of 32 inches. That would mean your replacement is an A32 www.amresupply.com/part/4L340-34-inch-X-50-V-BELT If you're replacing the belt on a washer you can also try to find an exact match. www.amresupply.com/catalog/Belts-Idler-Pulleys-637140-AI1H If you enter your washing machine model number in the search on our website it will likely bring up a parts breakdown with the parts listed on the side.

I have a belt that measures 35.3" outside circumference, with a width of 3/8", and height of 1/4". Would that be a FHP 3L belt, since the width is less than the smallest classical belt A size of 1/2"?
Thanks for watching. I haven't seen YP in referenced to V-belts in general. The YP is likely just part of the manufactures internal system of naming. If you can find an exact replacement using that part number then that would be best as it would remove any doubt, but as long as you match the size and length of the belt then you'll be good to go.
trying to piece together a shop fan, took a rope measured 44 inches around both pully's . bought a v-belt 9455 . Measured 1/2 "×46" still to tight. any recommendations. Thanks.
Thanks for watching. If you're able to get the belt over-top of the pulley's then it will stretch with use and will. If it is too tight and it won't mount or won't turn smoothly when installed, then you might need to get a larger belt. The 9455 has an effective length of 45", so the 9460 belt might be a better fit as it measures a bit over 46"
I have an old craftsman drill press. I need to change the belts and they have codes of sr 210 or 4l 210. And the other two are sr 170 4L 170. Any way I can find a replacement for those? Thank you!
Thanks for watching. At AMRE we carry a variety of belts including the 4L 210 www.amresupply.com/part/4L210-21-inch-X-50-V-BELT and the 4L 170 www.amresupply.com/part/4L170-17-inch-X-50-V-BELT
Thanks for watching. That is a hard question to answer as it depends on many factors. If the alignment and tension are right, then a belt can last years without too much wear. In other cases belts will wear down much sooner. If you notice that a belt is wearing down quickly then its often an alignment or tension issue.
Hi Barny, thank you for watching! We haven't done any videos for automotive parts as AMRE is more focused on the parts needed to keep one's property running effectively. To measure a serpentine belt you can take a piece of string, you'll need about 9 feet. Looking at your owners manual or any reference diagram for your vehicle, tightly wrap the string around the path of the serpentine belt and mark the point that the string overlaps with itself. Now measure the length of string it took to wrap around the path of the serpentine belt. Purchase a belt one size smaller than the size you measured. The actual belt will have tension on it, whereas the string doesn't. If you don't have a reference belt, you'll need the same width belt as what fits in the pulley's with the same number of grooves. Hopefully this helps. If you're curious you should check out more videos on our channel as they are just as detailed as this one. For example we have a whole series on water heaters maintenance and repair: th-cam.com/video/BHUPFLbb8NY/w-d-xo.html
Thanks. I have a Earthquake Rototiller # 6015v The belt is a cogged 31315 4XLA. I have found it impossible to cross reference. They designed it so you have to buy one of their 50$ belts. They could have put two of the regular belts on it. Never another Earthquake machine. I did order a AX24 - AX-Section Cogged V Belt. We will see if it works.
@@AmreSupply Do belts come in a designated list of sizes or are they available in a continuum of sizes at the whim of the manufacturers? Like is there a 3L366 belt or some such oddballs, or only in steps of 5?
@@hwingerrr5680 Thanks for watching. It depends on the manufacturer but often there are more sizes in the mid range where there are more uses. Since most motors can be adjust, this covers for slight variations in length. As you get into very long belts, there are less available due to it being more specialized.

I have a v- a-23 belt that I measured the outside to be 23 . Everything I find on line says it’s 25 inches long ! What did mean by subtracting 2 inches ? I’m not sure what I’m missing!
Hi Craig, thank you for watching. An classical A-23 belt should measure 25 inches in circumference on the outside and 23 inches on the inside. A 4L-250 FHP belt will have the same exact measurements. Its strange that a belt with A-23 printed to measure 23inches on the outside, but for getting a replacement as long as the measurements are the same then it will fit.
Thanks for watching. An M type seems to be more of an uncommon type. It's not one that AMRE carries and there is less information available about it. The M-type is likely shaped and can be measured as one of these classical shapes but might have extra properties such as long life, or extra strength for it's size.

Thank you. Very helpful to know how to get the proper measurements and what the codes mean.
You're welcome Keith! We're glad you found it helpful!
Does a B belt have more grip--less slippage--than an A belt? I have a wood splitter that slips on the pump pulley with a difficult split using an A belt and I'm wondering if changing to a B belt will improve the grip significantly.
Hi Don, thank you for watching. Overall its best to match the belt width to the intended design. Having an ideal tension (tight but not too tight) and a clean belt will help prevent slippage. If you're curious to learn more this video did a great job explaining how to address slippage. th-cam.com/video/syWiGYDOM70/w-d-xo.html
Great video!!! But i want to buy a belt for my lawn mower. They sais it is a 5/8 belt by 84 inch. But it said "B" and "5L" on the packaging. So it is not really a 5/8? A 5/8 is a 5v belt right?
Thank you, we're glad that you found it helpful! As you can see at 3:48 belts that are 4L will be the same as A. Belts that are 5L are also a B. The width on the B & 5L is 21/32 which is very close to 5/8 (which would be 20/32). So in this case 1/32" difference in width will not matter.
I need a washing machine belt M with an inner circumference of 25 inches. What belt should I buy, is it M 25, M 26 or M 27? Thanks for this video.
Thanks for watching. To find a matching belt you can enter your model number for your washing machine into this tool: www.amresupply.com/lookuppart
Or match based on outside circumference as M belts are designated by outside length.
Sir,i am from India i have a wet grinder and that belt is broken difficult to find the same the belt number is poly V belt 4PJ 745 so what is the alternative i can buy please help me
Thanks for watching. We don't have a parts list or cross reference with that particular number so we can't give you an alternative part.
I have a belt that is marked as L4 1177 K, what is the length of this belt? Is it 117.7” long?
Thanks for watching. There are a lot of different numbering that can appear on belts. It's best to measure the belt following the steps in this video.
I’m looking at a pulley that says it accommodates “1/2” ABS belt style.” Does anyone know if that 1/2 inch would be referencing the top width, or the depth of the belt? Thx
Thanks for watching. If it only lists one number than that will be for the top width. You can see here on our website that Deep V belts are listed by top width as the main way of sorting: www.amresupply.com/catalog/3V-Deep-Wedge-V-Belts-HR2G
3V and 3VX belts are 3/8" or 9.5mm wide belts ( not 1/2" wide as mentioned )
You are right, thank you for spotting that. The pinned post has been updated.
Thanks for the video I have a belt marked ak 34 what is the k for
Thanks for watching. The K likely stands for kevlar.
I am trying to find a Gates Truflex 4LXA720 belt but cannot find it anywhere. Where can I get a similar belt and what size do I need based on the markings?
Thanks for watching. From the number it seems like it is a 4L with a length of 720. If the belt is cogged you'll want to match that. There can be some variation in how these are numbered and what extra letters and numbers are added depending on the application. In any case you can still doublecheck and measure the belt.
Thanks for the video. Any idea what code "O-560" means? The number "29" also appears on the belt, about 1.5" away from the "O-560". It's a belt off of a cheap, imported drill press. The measurements are: 3/8" wide x 1/4" deep x 24" outside diameter.
Thank you for watching! It seems like the O-560 code is likely a manufactures internal number rather than a standard code, it doesn't line up with any codes or measurements that we know of. If you found another belt with a O-560 code or designation, it will likely be a direct replacement.
I know I'm late but better than never.
There is, indeed, an O type V belt. At least my drill press from Taiwan is using this type of belt.
Just like A, B, C, D... The number next to the designated letter is the inner length (millimeter).
You can search for O type V belt on AliExpress.
@@namtrieunguyen7630 Thanks for the information. It was helpful.
Hi, can I use a A series belt to replace an 4L-340 belt? May I also know what exact code should I be looking for an A type of belt? I would use it on my old washing machine. I would be grateful if I get a free answer from you. TIA
Thanks for watching. If you have a 4L-340 belt that measures 34 inches from the outside circumference, then the matching A belt will be also have an outside circumference of 34, subtract 2 (as mentioned at 2:57) and you get an inside measurement of 32 inches. That would mean your replacement is an A32 www.amresupply.com/part/4L340-34-inch-X-50-V-BELT
If you're replacing the belt on a washer you can also try to find an exact match. www.amresupply.com/catalog/Belts-Idler-Pulleys-637140-AI1H If you enter your washing machine model number in the search on our website it will likely bring up a parts breakdown with the parts listed on the side. Here's an example: www.amresupply.com/lookup/304244/2305336

I have a belt that measures 35.3" outside circumference, with a width of 3/8", and height of 1/4".
Would that be a FHP 3L belt, since the width is less than the smallest classical belt A size of 1/2"?
Yes that would be a FHP 3L belt as listed here: www.amresupply.com/catalog/3L-F-H-P-V-Belts-HR2
Very informative! BUT, my Snapper lawnmower uses a 7158101 YP belt. Do you have any idea what the YP means ?
Thanks for watching. I haven't seen YP in referenced to V-belts in general. The YP is likely just part of the manufactures internal system of naming. If you can find an exact replacement using that part number then that would be best as it would remove any doubt, but as long as you match the size and length of the belt then you'll be good to go.
Ok, thanks for the reply.
itaintmebabe99
most snapper blade belts are a six sided belt.
Randy Deskins OK, so you don’t know either !
trying to piece together a shop fan, took a rope measured 44 inches around both pully's . bought a v-belt 9455 . Measured 1/2 "×46" still to tight. any recommendations. Thanks.
Thanks for watching. If you're able to get the belt over-top of the pulley's then it will stretch with use and will. If it is too tight and it won't mount or won't turn smoothly when installed, then you might need to get a larger belt. The 9455 has an effective length of 45", so the 9460 belt might be a better fit as it measures a bit over 46"
I have an old craftsman drill press. I need to change the belts and they have codes of sr 210 or 4l 210. And the other two are sr 170 4L 170. Any way I can find a replacement for those? Thank you!
Thanks for watching. At AMRE we carry a variety of belts including the 4L 210 www.amresupply.com/part/4L210-21-inch-X-50-V-BELT and the 4L 170 www.amresupply.com/part/4L170-17-inch-X-50-V-BELT
Good morning , i want to ask how long lifetime of vanbelt
Thanks for watching. That is a hard question to answer as it depends on many factors. If the alignment and tension are right, then a belt can last years without too much wear. In other cases belts will wear down much sooner. If you notice that a belt is wearing down quickly then its often an alignment or tension issue.
So have you done a video on how to measure automotive belts (width and length) when all you got is the engine (old belt long disappeared).
Hi Barny, thank you for watching! We haven't done any videos for automotive parts as AMRE is more focused on the parts needed to keep one's property running effectively. To measure a serpentine belt you can take a piece of string, you'll need about 9 feet. Looking at your owners manual or any reference diagram for your vehicle, tightly wrap the string around the path of the serpentine belt and mark the point that the string overlaps with itself. Now measure the length of string it took to wrap around the path of the serpentine belt. Purchase a belt one size smaller than the size you measured. The actual belt will have tension on it, whereas the string doesn't. If you don't have a reference belt, you'll need the same width belt as what fits in the pulley's with the same number of grooves.
Hopefully this helps. If you're curious you should check out more videos on our channel as they are just as detailed as this one. For example we have a whole series on water heaters maintenance and repair: th-cam.com/video/BHUPFLbb8NY/w-d-xo.html
Thanks. I have a Earthquake Rototiller # 6015v The belt is a cogged 31315 4XLA. I have found it impossible to cross reference. They designed it so you have to buy one of their 50$ belts. They could have put two of the regular belts on it. Never another Earthquake machine. I did order a AX24 - AX-Section Cogged V Belt. We will see if it works.
Thanks for sharing your experience. Keep us posted if it works!
@@AmreSupply
Do belts come in a designated list of sizes or are they available in a continuum of sizes at the whim of the manufacturers? Like is there a 3L366 belt or some such oddballs, or only in steps of 5?
@@hwingerrr5680 Thanks for watching. It depends on the manufacturer but often there are more sizes in the mid range where there are more uses. Since most motors can be adjust, this covers for slight variations in length. As you get into very long belts, there are less available due to it being more specialized.
Why two v belt using some applications, for example lathe machine, can we use single belt
Thanks for watching. Using 2 v-belts is a way of transferring more power with common, less expensive belts rather than using a single larger belt.
What size belt. For 48"husqvarna
Thanks for watching. For that belt you should be able to measure it and determine the size based on the instructions in this video.
23100-GK1-0030-Bando do you know the standard size of it?
Thanks for watching. That is not a belt that is in our system. You should be able to measure that belt using the steps in the video, or do a google search as it might be within other databases.
Hey sir,, can i ask what is the centimeter of A-33??
Thank you for watching. The dimensions of a A-33 belt are listed here: www.amresupply.com/part/4L350-35-inch-X-50-V-BELT You can convert any measurement using an online converter or google.
I have a v- a-23 belt that I measured the outside to be 23 . Everything I find on line says it’s 25 inches long ! What did mean by subtracting 2 inches ? I’m not sure what I’m missing!
Hi Craig, thank you for watching. An classical A-23 belt should measure 25 inches in circumference on the outside and 23 inches on the inside. A 4L-250 FHP belt will have the same exact measurements. Its strange that a belt with A-23 printed to measure 23inches on the outside, but for getting a replacement as long as the measurements are the same then it will fit.
what are M belts like M-21?
Thanks for watching. An M type seems to be more of an uncommon type. It's not one that AMRE carries and there is less information available about it. The M-type is likely shaped and can be measured as one of these classical shapes but might have extra properties such as long life, or extra strength for it's size.

some id's have a "W" at the end ... what does the "W" mean?
Thanks for watching. That isn't too common and might be just a manufacturer's addition. do you have an example of a code with a "W" at the end?
@@AmreSupply I see the W as a subtext. 4L 300 W. Some suppliers have the normal names and another set with the W at the end. So they must be different.
@@MrJazzohjazz The W likely refers to the belt being "Wrapped" meaning its made with an additional material that increases its strength.
@@AmreSupply I really appreciate your replies and they have been helpful. The fellow at NAPA said the W means a higher quality belt .... So .... I purchased the $L300W and will try it out tomorrow. Again, thanks for your help.

Pull this video and put out a New Correct one.
Thanks for watching. We have posted the correction as a pinned comment so that it is visible. We can tell by the comments and likes on this video that many people are finding this video helpful even with a typo present. If we remove the video it would lose all views, comments and interactions. Re-uploading it would mean the new video would start from scratch and wouldn't show up in the search and is unlikely to generate the same kind of views. That would mean thousands of people would not see the new video and the net benefit to people would decrease.
@@AmreSupply I thought you could simply 'cut' out the erroneous audio and substitute correct stuff. I didn't realize it would sink the ship. Good info as is.
@@gordbaker896 It would be helpful to be able to swap out parts of videos but in a way having videos on TH-cam unchangeable prevents deceptive practices. Content creators would game the system for viewership, post one thing then swap it.
