I was at local doo dealer today and they had a Rene 850 on floor. Once I pulled the clutch cover I could see the clutch alignment out by a mile just by looking at it.

What is a Rene?

Renegade. I am in Michigan right now so summits are not common.

Can you just pull all of the plastic from the cover and put the belt in your pack? Or does the oil tank become vulnerable?

I personally would be looking at what is creating the belt heat. Gearing, clutching, belt alignment etc. To me, pulling felting and having to put holes in everything is wrong for a new $15000 sled. Scuffing the clutches and belt and any cleaning is good.

I was looking at my 850 and noticed the side panel fits around the clutch guard so tight I don't think cutting holes in the guard will do much for air circulation. May have to put vents in the panel around the clutch guard area to let the hot air outside.
My 2 cents Tar

This is a total replay of 2008/09. Venting/cover mods/gearing/clutching are all band aids. Each one will help in small amounts and a full combination of above will almost work, but bottom line is heat is generated from alignment. You can never have perfect alignment in entire rpm range when you have solid secondary. Motor and chassis flex under different loads and conditions. How many guys you hear that did a floating secondary and still blow belts?

Alignment can be one of the problems but I wouldn't say that is the problem completely.
Heat is slippage, and that can be a combination of a few things.
And yes you can achieve this with out a floating secondary.
Have for years. Lol

I see you your signature you have a 2012 XM. As I said above, the 12s have longer secondary shaft. Very few 2012+ summits had issues. If you have a pre 12 your alignment is off, guaranteed. I have never seen one that is in. If you have belts last thousands of miles on an XP, hats off to you.

Had 2008 , 2010 ,2012 and now 2016.
Never have wreck a belt on any of them with lots of miles and big tracks.
Learned years ago to use clutches that work and transfer them ? Lol
Keeps things simple and no issues .
Secondary has never been floated on any of them.

So you were not using a stock clutch setup? Then that makes sense. Anyone that says the XP did not have a belt issue is in denial. Seems to be all to common with the Doo folks (which I am) that they never wanna admit there is a problem with their loyal brand. I have run into ppl that swear they have zero belt issues (but replace a belt every 750 miles) look at their alignment and tell they they are out. Give them a kit and the belt last 1000's of miles. I for one fell for the "there are no belt issues with XP's" and bought one. 100 miles I would get outta a belt. On top of puddles of coolant, bad fuel gauge, ****ty heated grips, etc.... The sled was a pile BUT it always started. Something I see my Cat and Poo guys struggle with. But with the XP disaster, I will wait a few yrs to buy one. Been there, done that.

First year sleds are always trouble.
Never again for me either as have fell into that pit a couple times. Lol
Last year before model change seems to be the best and the cheapest.

Truth to that I feel as well, had a few first year sleds.. first year Xp, first year Etec, always a few bugs to work out, that r&d overlooked.. no different in trucks, tractors, combines...

Now saying that, the only reason I never did the G4 was for the track.. sure look strong thou..

Wapow · Dec 25, 2016

I had an '08 XP that went in for warranty work way too many times in the first season (two failed driveshafts!). And I too vowed to never again buy a first year sled. I was dead set on getting a '16 holdover T3, but then I rode one for the first time two weekends ago, and came away thinking it wasn't much different than my current sled ('09 XP modded to full XM chassis). So, I started looking at other options and wound up buying a G4. The hype and real world ride reports got me believing that the improvements over the T3 were worth the extra cost and first year sled gamble. The XP had similar hype, but it didn't deliver. After one ride, I can confirm that this rig does. I'd read a bunch of comments about the G4's throttle response, but they didn't do it justice. I was trading back and forth with an XM and the G4 is just way more fun to ride. The XM feels like a 600 in comparison. I'm really glad I didn't buy a holdover T3 (at least for now).

venting

I'm a flatlander and removed what you guys are removing. I added some hole to help let the air out.

Summit74 · Dec 26, 2016

After trimming the bottom of the clutch cover, I feel in need something to keep snow out of the footwell on the clutch side. Anyone else come up with something to keep snow from being kicked through into the clutch compartment.

Vertical-Extreme · Dec 26, 2016

Expert advise lol. Hey guys take your brand new sleds, rip **** off
And cut / drill holes all over them until we actually figure out whats wrong with them.... Nice work skidoo. At least in 2012 cat was giving away free belts like candy

In cats situation, it was an out of spec part from a vendor that supplied it. Some were good parts from a different vendor but the ones that were bad had people modifying braces and vents to fix a problem.... Good luck. Not sure if that is the case with the G4 though... I think I'm finally gonna rip out all the foam on my 16 t3... Water drippage on clutches no beneu.

Vertical-Extreme · Dec 26, 2016

I wondered if it wasn't the same issue on the doo's. It seams so random. Maybe 2 different suppliers on the motor mount rubbers or something. Different durometers of rubber ???
