I just took my 2012 Outlander 1000XT in for an oil change/ service today and had the dealer check out my belt and clutches. They greased the one-way, cleaned the clutches and installed a new drive belt. I kept the old belt as a spare as it looks pretty good and has 1700 miles on it. When I got home I noticed the old belt has a different part number (280 360) than the new one on my bill (715 000 302). Does anybody know why the part # is different? Is it an updated belt? How is it different than my stock one? I tried searching the forum but came up with nothing.
