Default Re: V belt, How buy?

Chain auto parts stores have the belts listed by size, but the guy behind the counter does not know it.

Belts are listed by width & length in the part number. The width is described in 32nd inch increments. A 15/32" wide belt is a "15", a 17/32" wide belt is a "17", and so on. Odd numbered 32nd sizes are standard.

The length is also part of the part number. A 29" belt would be a "290". A 34 1/2" belt would be a "345"

So, a 15/32" wide 29" belt would be a 15290, sometimes listed as a 15-290, or they reverse the number (dayco) 29015. But the size of the belt is always buried in the part number.

The length of the belt is listed at the gauge line, which is about .100 below the top surface of the belt.
