New Belt drive fail

Status
Not open for further replies.
Just a quick point on belt vs chain drive...

At the end of the 2011 season I rode in the spring on my '11 Pro and blew up my chain and gears. We were jumping in heavy slushy snow. I thought my track was ratcheting but I lost some teeth on the top gear. I lost all the oil when we tore it down on the trail. That sled rode another 20 miles with no oil on three teeth! Finally it was too hot and all the teeth went. Polaris covered new gears and chain but made me pay for the oil.

My point is that I would have much rather lost a belt. I wouldn't have had the heat issue. If the cogs let loose I likely would have been able to get the sled up to speed and cruised out. If someone had a belt at the truck they could have gone back and picked it up. I like the progress of the belt even with the growing pains.

EXACTLY!!!


Your chain situation could of easily gotten worse as well trying to ride it out. Wedge some parts and break the case. Your talking some hours to repair now not just minutes to change belt.
 
--The drivetrain does not need to be protected by a belt drive. It handles a chaindrive without issue.

--People will just have to wait and see if the belt drive suits their riding style, overall, it should be OK but still a higher maintenance item than a chain drive due to being more conscious of riding style and belt replacement

--I just have a recurring thought of climbing a chute or steep hill, getting some air and coming back down under load and stripping it out. Then what? Certainly can't climb, do you still have brakes?

--With a low HP motor at altitude and lightweight chassis, it may be fairly reliable. I think other aftermarket versions allow for more stress due to having a belt adjuster and more contact surface area of belt on gears.

I had issues, see my post above. Winner = belt.

We don't know this yet (failure rate of belts). In my case it would have been much more to pay for all the chain case parts. Winner = belt

If the cogs are failing but the belt is intact then you still have brakes. In my case with the chain it locked up. Then when we removed it I had no brakes. Winner = belt.

I too would have preferred a tension. Tell this theory on low HP to the funny car/dragster guys. Biggest hp motors on the street. I really doubt that a Doo or AC at 10 more HP crosses the threshold for using a belt!
 
What is different about the Polaris belt than the belts being used on some of the aftermarket sleds over the past several years with bigger tracks and more power? I have heard of belts breaking from alignment issues but I have not heard of them stripping the lugs....or maybe it's one of those things that just isn't talked about. Is it simply a belt construction issue?
 
If there is a issue my guess is that it will be related to poop belt design. It will be cured by buying a quality aftermarket belt vs running what ever poo found that will be the cheapest belt that meets there needs. Worst case scenario the aftermarket will come out with a bolt on tensioner.

Not sure about the belt life yet cause we don't really have any real life experience other than you virtual experts of course, but if you're right about the belt drive being better suited for low hp, imagine how perfect it would be on the Doo. The 10 hp more delivered thru the backwards design clutch will result in way less stress on the final drive, as is evident in the snow.

The belt used in the Direct Drive is the same belt they have used in there Victory motorcycles for years. Not some cheap belt that would just meet there needs....
 
So are there more pictures of this? Is there anything to show there wasn't a stick or rock or something jammed in there? Are the pulleys in pristine shape?

We'd love more to the story.

the belt shown above is off of a buddies of mine, if it happened durring a climb (which is/was the rumor on the other forum) then he was begging for it as the other pic i will post here shows how much snow there was. nobody is going to be able to give any real feed back on the belts this early in the season. (other than the demo tour last year which i personally rode one that had over 1200 miles on it on the original belt) i would account the three belt issues that i have seen including this one so far to lack of dealer knowledge on set up, running the sled on a sled lift with the belly pan rubbing on the bottom of the belt, or riding in to low of snow conditions and hitting something under full load with the track. if you look closely at the outside cogs of the belt in the picture it at least appears that they are rubbed off or ground down in the same area as which the inside cogs have the issue.

obviously not enough snow to be climbing ANYTHING

I thought the Victory belt was only about 1" wide and about 5 feet long with a sprocket about 12" in diameter? Or do you mean the same belt mfr?
I'm not sure the loads on a bike belt drive are anything like the sled setup.?? The bike belts are puny by comparison but seem to last forever with a huge belt-to-sprocket contact area.
 
Same MFG and same design, material, strength, but your correct probably not a belt off a specific model motorcycle as the belt length would be of coarse longer.....

Have you ever broke a chain? I have on my Doo...exploded the entire case + cover + gears + chunks out of the brake rotor and belly pan. No brakes and I was going downhill into a corner on my way back to the truck. $1,000 damage + a scary few seconds. At least the belt would be an easier and cheaper fix with theoretically less drama and damage to the sled.

--yup--

--Was climbing up a steep mtn, chain broke, motor revved, brakes didn't work, sled rolled backwards, track locked up, handlebars were over my head, let go, tumbled down the mtn, sled literally flew by me 3 ft in the air upsidedown going backwards as it rolled / bounced passed me down the mtn. Got towed out, did not break the chaincase. --Fun Day--
 
I don't know if the belt drive will be good or bad or whatever....

But this one time, on the mountain, I saw an exploded chaincase on a guy from Spokane who rode Fish Creek (it was supposed to be a one day trip).

Broken gears, broken chain, broken chaincase on the side of the mtn above Leo Lake. (Yeah, that's a long way in).

He doubled up on his buddy's sled for the ride out.

Instead of going back to Spokane, he spent the night in Missoula.

Bought some gears and a chain the next morning.

Rode back in the next day (doubled on buddy's sled of course).

Replaced gears and chain, reinstalled pipes (It was an 800 Ultra) and rode the rest of the day without chaincase oil or a cover.

LOL.

THAT was a MESS.

LOL.
 
Continuation of belt drive fail thread

FFS.........this site still hasn't figured out that charging is retarded?

please continue this thread in here so that all those that refuse to be bullied into paying for something that should be free to the members and paid for by the advertisers can see it

thanks and have a nice day!

One thing that Polairs has not been guilty of in the past few years is using cheap or poor-quality belts.

The Mitsuboshi 3211115 belt is the highest quality and most durable belt offered on the market.. And standard on ALL PRO RMK's

The Gates cogged belt is the same type of belt with specific dimensions, as the the ones used in harleys and Victory bikes, and by C3 and CMX in their sled stuff.
 
really?? oh that's a great way to start a thread. this isn't going to go off topic at all. give me a break.

my response, to your overly angry, sand in the v-j rant, well the info must not be that valuable, to you, if you are too cheap to pay for it. there are multiple other FREE sites you are more than welcome to visit. i'm sure they would be happy to have you. get over yourself and either pay up or move on. have a nice day.
