Could be, they also said that it would run with no teeth at all. What did you do to strip that many?

Reminds me of the first second and third year of the XP blowing belts. i'd carry at least one of each.

i do find it kind of funny.......I remember getting flamed last year about mentioning the fact that if the belt were to break......and now we have proof that it isn't indestructible as some led people to believe.....you have no way to stop!
great design putting the brake rotor on the jack shaft.......bwahahahahahah!!!!!!

I'm actually wondering now how long till the first law suit is filed by someone unable to stop due to a broken belt and causing a crash........PEOPLE......SOMEONE IS GOING TO DIE! or at least get severely maimed

That really surprises me. We run that type of belt drive system on all kinds of big industrial equipment and I've yet to see a failure like that.

so your industrial equipment has a 50-60 pound track spinning at 60-70 mph and then in a split second, by grabbing a fist full of brake lever is required to stop instantly? something is going to give and I believe those pictures^^^^^^^show the weak link
Polaris even admits that the belt is designed as the weak link.......spare cog belt it is. It's nice to be proven right.

Is an xp the only sled you've ever owned? Never broken a chain before? See if you can figure it out from there.

How do you plan on stopping when you your chain breaks?! I'm sorry but it's the same problem. Chains break and belts break. Motorcycles use the same system, and people have been putting on after-market belt drives for a while. This picture shows that only the teeth have come off, and even on those broken sections there is still some traction left between the belt and the cog. Polaris has stated that even if all of the teeth were to be stripped there is enough tension on the system that it will still function properly. So it comes down to the belt actually snapping, which is just as likely as a chain snapping.

my point was that it probably doesn't see the abrupt changes required by a sled drive system......maybe, but I doubt it
actually no......only one I haven't owned is AC. Yes, I have had a chain snap. whats your point? chain on my XP snaps and I can stop because the brake rotor is on the drive shaft...........maybe you missed the point that the brake rotor on the 2013 belt driven poo's is on the jack shaft........Now lets see if you can figure it out from there

I do completely understand your post. Guess where the brake is on Polaris' 2012 chain case...the jack shaft. As I said in my post, it's the same system.

Wait you guys have no breaks when your belt goes? Oh my. I'm surprised that's even legal. Would never get away wih that on a motor vehicle. Oh I blew a driveshaft no breaks look out!!!!!!!!!!

Is Doo the only Manuf. that mounts the brake on the drive shaft ?
Yeah I get it. Your quite clever. Why do you think I brought up the xp in my original post. You should probably start a thread warning snowmobile owners who don't have a xp that they are going to die. That's approx 50 years worth of snowmobiles. That's a big task. But I'm sure your up to it. If the belt drive doesn't hold up that sucks. Don't be such a alarmist dude.

The brake rotor has been on Polaris' jack shafts for well over a decade !
Were did you come across this picture of the damaged belt from ?
