Kurt's Polaris gear down kit failure

[nort10]

I'm sorry to hear about your belt. I just wanted to share my experience with the gear down kit....I've got 450 miles on my gear down kit and I ride hard steep technical terrain (on and off the throttle). I don't have a turbo on it my sled, it is a 2014 pro 163 with Kurt's gear down kit & clutch kit. I think every one that rides the steep and deep (off and on the throttle) should really spend the money and get this kit. My clutch belt has 500 miles on it now, I put a new one on 50 miles before the gear down kit and it looks great yet. My first belt lasted 174 miles before I put the new one on and I've never got much over 300 miles on a belt before I would lose rpms/performance from a belt. I believe the gear down kit lowers the belt temps and this is the result in better belt life for sure!!! Also riding my friends stock 2014 pro 163 and back to mine I really noticed the difference in throttle response.

Kurts Polaris gear down kit

I'm pretty sure this is not a TKI kit, like the post reads Kurts Polaris gear down kit. Notice their is no belt tensioner.

Looks to me like a foreign object got in there for the belt to break like that. I would love to inspect both sprockets.

Have you contacted Kurt's and if so how have they responded?

Heat! I have heard of just about every brand of belt or belt system failing when its that close to a turbo. One particular failure on a popular aftermarket system failed in a matter of miles just heading up the trail....turbo heat. He added a heat shield and it has been flawless since.
I wouldn't blame the belt or a flawed design for this failure, theses belts just cannot tolerate much heat.

Nothing foreign was found in engine bay I'll pull the pulleys and post pics.

Agree 100% with the pipe at 1000 degrees about a inch away that belts toast, do your self a huge favor and convert it to a chaincase

You have some of the most knowledgeable guys on the forum repeatedly telling you that the exhaust heat is definitely a potential problem, and likely THE problem.....it is worth putting some weight in to that.

Kurt also told me..."No break-in. Ride the crap out of it out of the gate."


The tear goes across a couple teeth on the belt. Without personal inspection, the picture looks like some foreign object cut that belt.
But, with the turbo and heat being so close it's hard to ignore that possibility.

 

[seanc]

ok. so why does BD sell this kit? why did kurt build this sled for me like this? shouldnt be breaking belts like this...

 

[2XM3]

if it were mine, id wrap the turbo exhaust pipe with the really good circle track heat wrap, run a blanket on the turbo and build a heat shield around the lower area.....put on a new belt and go have fun. Or just slap on a new belt and go ride till it breaks again then do the heat wrap, who knows it may in fact never ever break again. What had Kurts said about it??

 

[05900]

shouldn't couldn't wouldn't....I'd wrap pipe ( keeps heat in ) good thing, blanket exhaust side of turbo ( keeps heat in ) good also. If it is uncomfortable for your ungloved hand it's to hot for the belt.
Maybe not next ride but probably the next or maybe the one after..

Strange. I talked to Tom Kobza yesterday. He told me heat was not an issue with his belt system. That the stock Pro seemed to produce more heat and once swapped to his system guys were reporting cooler temps. I asked him if it was necessary for a heat shield or or venting. He didn't seem to think so.

Also, he claimed the only belt that had been reported as stripped or torn was from a snow crosser.

 

[seanc]

i will try to wrap the pipe and see what happens. strange that BD would come out with this kit WITH a problem. and kurt is selling them all set up.

 

[Jaynelson]

Have you asked "Kurt?" He's the one who told you to try and break it sounds like...might want to get his thoughts?

 

[polarispro]

We are running the TKI kit on several pro's and some xm's, no problems at all just great results. Tom's kits and craftsmanship is seconds to none and he is super cool to deal with. Give him a shout it will be worth your time. www.tkine.com
