Finding Belt Size based on Numbers

[Rustyshackelford]

Hi,
I replace my belts a few years ago based on the suggested sizes and I want to buy one size smaller on two of them. How can I find the number belt I should buy if:
Goodyear gatorback 15591 is one size too big
Goodyear gatorback 15461 is one size too big

I googled belt size charts to no avail. Thanks in advance

Can you find some crossreference numbers that are the same as those two belts? Reason I ask is that some belt makers code the length into the part number. IE an xx945x belt may be 94.5 inches long. So get the Goodyear belt number chart and look at it, they are usually arranged from smallest to largest (most are anyway) and look for a pattern that would indicate a half or one inch increment. In your examples it might be a 15581 and a 15451 that would be an inch shorter than the two you have.

It looks the 3rd and 4th number is near the length

Goodyear gatorback 15591
Belt Length (in): 58.50 in.
Belt Width (in): 0.438 in.

Goodyear gatorback 15581

Belt Length (in): 57.50 in.
Belt Width (in): 0.438 in.





Goodyear gatorback 15461
Belt Length (in): 45.50 in.

Belt Width (in): 0.438 in.


Goodyear gatorback 15450

Belt Length (in): 44.50 in.
Belt Width (in): 0.438 in.

In the future just google the belt number ,find the specs , then google "gatorback belt Belt Length (in): 44.50 in. Belt Width (in): 0.438 in." . All I did was take inch off the spec for the belt you posted .

Most brands and part stores use standardized numbering. 15 is the series which is equivalent to the 7 series in gates which is roughly a 3/8 most common for old school vbelts. NAPA of course likes there own unique way to number everything....... 17 series translates to a 9 in gates and are usually 1/2 wide most common for heavy duty and some automotive.

Serpentine belts have a numbering system on number of groves and overall length.

next 2 numbers in the middle is the circumference 59 or 46 inches. The last digit if not zero is a fraction of the length so maybe 59 1/4 & 46 1/4. These are not exact caliper measurements but you get the drift and very easy for a counterman to give you a different size based on your request.

Unfortunately there are probably two dozen + sizes in between a 46 & 59 inch belt. Run a string in the the pulleys and measure to give you a benchmark to start from.

See link for Gates info. Once into belts you can see dimensions etc.

Had to wait to get the link at work! May not be needed any longer, but good info/resource to have.

On other machines with unknown belt numbers, I've just brought the old belt to a parts store and used their sliding belt guage.

Find the belt that works and note the number then cross to other manufacturers.

View attachment 716313Find the belt that works and note the number then cross to other manufacturers.

That works if there is enough belt left to measure or the belt isn't stretch to far. I got one of those , I don't think I have ever used it . It was left behind in a old auto parts store that I do building maintenance on .
