Big break

[Bigwin]

last night on the lake , the Apex let me down at the worst time over 3 inchs of ice,,,,,.end result, in sequence.belt blew into 1 inch pieces,,,,.bushing i figure let go on the inner sheave of the secondary, in turn destroyed my buttons, ramp , helix, , pushed out the bushing on my helix,, completly kerfuckled everything.seen this happen on friends Turbo's, and Supercharged. time for a big change this spring..sled only has 3700 kilometers. anyone else have this similar meltdown.

What have you messed with? This just doesn't happen when the clutches are in proper tune. Sounds self induced with clutches or alignment that is out of tune.

hey...damn that sounds bad...

were you on lake o bays?.....man there isnt much ice out there im hearing....Dean said he ran it and it wasnt a pretty site!...lots of water i guess???

so did you blow the belt then make a mess basically?...ive seen it in deep powder....but usually its a belt with over 1000K on it.....was it an older belt??....makes a big mess i know!

Ive been running mary lake here abit,but its not too thick at all and really slushy

heat

i had the same thing happen to my rx 1. it was my own fault i was trying to run a green secoundary spring (that work realy good for the 660) and the belt would slip while running on the trail heated up the secoundary so bad that the bushings came out of the helx and melted the plastic shoes. what a mess and hot wow . plus melted the belt.

Improper clutching that causes too much friction
that causes too much heat that sooner or later
results in metal fatique like yours!

Ok this is what I did.. Nov I replaced my bushings on my Dalton Helix and my inner sheave on my secondary. I though there was a little to much slop and I had approximately 1700 miles on them hard lake running so there cheap replace them... I red lock tite them reassembled and drove it 5 to 6 times.Last week are lake was finally looking like we where going to get on it so I took off my Dalton setup reason's unknown ,put in the new stock Primary spring,stock helix that was machined in 06, stock weights,and the kicker a new White secondary spring, wrapped to 70 degree's oh and also a new Carlise belt,keeping in mind I just took off a old Carlise belt. Reshimmed everything properly and way I went onto the lake.The rest is History.The only thing that Dean and I did cause his was the same dilimma last year was to disturb those bushings mainly on the secondary and also both had on a Carlise belt.

I have heard that the ultimax 3 belt was prone to failure. I have been testing the ultimax xs and seeing huge wear with it. It may be possible that the bushing tightened up with loctight and caused the clearance to shrink and stick with an increase in heat. In an Attak the black/white driven spring is only tightened to 60 deg.,3-3 using stock clutching. Any time you wrap the driven tighter it builds heat. Something is not right with your setup. I would assume this is in an apex. Try using 100% stock clutching if its broke in, including the 8DN belt. I think it will run 5000 miles for you without even batting an eye.

This exact thing happened to me on my SRX years ago except my secondary bushing pushed through to my jackshaft bearing taking it out as well. The cause of my mishap was going to aftermarket slider shoes in the secondary. Thinking I was saving a few bucks, turned out the aftermarket shoes can’t take heat and melted away when I was WOT in soft snow for a long period of time. Literally mushroomed the little shoes and through my secondary out of wack spitting out the bushing.

I only use OE Dan especially when Iam rebuilding prime's or sec's so that blows that theory.as far as wrapping the white spring by 10 more degree's I don't think that would make this thing self destruct. especially the White spring...BUT MAYBE""Iam not ruling anything out.. I had 8 miles on the belt.I just put on the new Carlise,, had 1000 km on my old Carlise..I am wondering weather that bushing didn't hang up. Due too the loctite.. Its just habit to me to use it...Once these sleds come with Harmonic Balancer's I"ll throw away my numerous bottles of assorted coloured loctite...Dano don't forget about the Chile fest this weekend at McCann's also let little big guy Dan Baker know.
