snapped my helix in 1/2!!

[backcountryislife]

Hey, has anybody had this problem? I just had my helix snap (couldn't figure out what the vibration was till the sled wanted to start in 6th gear!!!) and not sure if it's a more common thing than I thought or if I should be watching out for it.

also curious for opinions on what kind of helix to run, I've got a 141 1000 with 185 or better hp, but ride at 10,500 or higher. I have a 36, tried & didn't like a torsional 34(didn't try to tune at all, just slapped it on from Qrieff's sled on sunday) and had a 44/40 for a while but it went through belts even worse than it does now.

btw, if anybody wants to sell a 09+ helix, let me know. If I could find one cheap I'd be up for trying about anything.

Rode with a guy Saturday thats 10 m8 did the exact same thing. The strangest thing we've ever seen, but perhaps there is an issue. Who else has seen this?

What failed first, the helix or the screws fastening it to the sheave?

I snapped the helix on my 07 m1000. It was the stock helix and I think the bolts backed off first and then the rest let go. Oh well I wanted the rktek setup anyways.

the helix itself snapped at the legs, bolts were fine.

Got a 40/36 coming from BDX to get me going, but I'm open to suggestions for anything different to try.

last year, i had some extreme heavy vibrations, had no clue until i got home and removed the secondary.....helix was almost ready to pop off and shoot parts through my side panel, lucky i found it before hand......and this was maintenance induced on my part, tried to use cheap screws from home depot after i did a helix exchange.....all bolt head snaped off, as if the OEM parts are not cheesy enough

are you saying the helix bolts were still tight and the helix split in two?

im having one hell of a time clutching my 2010, not sure my 43/36 is any better then the stock straight 36...and the torsional idea sounds good on paper, but i noticed zero difference when i tried one, it is nice to have the tweakable belt deflection when you change a belt

sidenote - i purchased about 80 of these suspect bolts a few weeks ago, never have enough

My guys bolts were fine, helix just snapped in half with bolts still in...

One of the guys I ride with cracked one on Saturday, clean through one arm, we didn't notice loose screws, I'll have to check.

Are you guys running a shift assist, i know they can bust because the bolts but i am wondering if yours didn't bind and even with the shift assist it could bind if bearings were bad, with the 09 and newer i would definantly add a shift assist those helixes look weaker with the reverse notch, how do the rollers look?

I broke three on my 07 M8 and my dealer could not figure it out. They all broke on the arms and the bolts fine and tight on everyone.

I sheared all 9 bolts on my secondary and blew it up. This was a complete warranty issue but today I blew up the spider on my primary. Complete BULL ****! I run a 2010 croosfire 800 withe the 141 powerclaw track, usually run @ 10k + elevation. Not happy with all the clutching issues! Been through 3 primary springs, a whole secondary, 4 belts, and now a primary. WTF

 

[Frostbite]

Do you guys have any pictures of the carnage? I'd like to know what to watch for on mine,

We you running the stock secondary spring or something stiffer?

I have the Skidoo Purple spring I'd like to run and it's a L O N G spring that may add a bunch more pressure on the weak spots on these helixes. Hum?? Maybe I'd better hold off for a bit?

Thanks for the information.
