will this blower belt work??

will a 14mm belt work on 13.9 pulleys? thanks Dave

 

Only for a couple of teeth, after about 4-5 teeth it won't line up, the belt won't wrap around the pulley correctly, and will cause excessive wear and will eventually will want to part ways with said pulley .
Hope this helps

 

thanks andy..Dave

 

I'm assuming the 14mm and 14mm GT2 belts are different? We've run 14mm GT2 belts on 13.9 pulleys with no issues.
