Since I carry heavy loads of ice fishing gear with tracks in deep snow or slush the poor belt takes a beating. I would narrow up a belt in one season. After talking with customer support at Timken they recommended the UA495 designed specifically for Argo. I’ve got two hard seasons on it with next to no wear. This belt has been replaced with the even heavier UXP495. Since this belt is a hair thicker it requires no engine table shims, unless you want it super tight as I tend to run it. Hopefully someone can benefit from this.
