Count the teeth on the big pulley. It's probably a 80 tooth pulley and your ordering belts for a 100 tooth pulley, or 100 tooth pulley and ordering belt for 120.
Jeeez. you ordered a notched V belt which is not the right type.
The teeth fit into the pulley grooves.
you need a toothed metric timing belt.

A little too small? Are you sure you've loosened the 3 bolts on the belt tensioner cam and rotated it?
If you don't have the adjustment wrench you can use a big flathead screwdriver on the cam adjustment.
The 570-5M-15 belt is the right size for 100T pulley.
lol ya I loosened them and used the tool. I watched a video on youtube and the guy was able to easily roll his belt on but mine... is there a size a little bigger I could buy? it would just need like 10 to 15 more teeth. I also learned that they aren't stretchy not even a little
