How many of you trimming the bottom's of your clutch covers? Rasmussen says cut, Norona says dont cut,,,, I'm kinda lost on this one :face-icon-small-con
To cut, or not cut.. that is the question

Depends, If it started busting belt after belt I'd rather say the sled is stock/ unaltered and try to get my belts covered under warranty. That's just me.
I'm with you, not sure if I should cut or not. I'm going to wait before cutting. The theory of it pulling air around but only if the guard is in not cut. I got a little breakin ride today and the clutch's seemed fine.
I cut mine last year and had 852 trouble free miles on one belt

Didn't cut mine and all trouble free miles.

I like to inspect my belt periodically through out the day and It’s a lot easier to get the cover off once it’s been cut.
I only blew one belt last year, but pulled a cord on three others that if I didn’t see would have ended up in a million pieces.

when its cut, it is so much easier to put the guard back on
These things build so much clutch heat I don’t think it matters either way.

Yeah, what did they call the running temps of the clutch ? 10% lower due to the zero friction primary? Sure.
Cut the bottom section that has the piece of foam on it, it is 1 inch by 2 inches it allows the air to escape, the guys who drilled holes everywhere might as well take it off, the cvt cover is designed to pull the air out through the left foot well. if you cut the bottom off you might was well take it off, something I don't suggest, it has nothing to do with belts blowing on 2017 model years some guys went through. If it was then it would have happened on the 12-16 model years. Keep the cvt cover intact but take out all foam and felt and in clutch area...
Ok, so cut the tab at the rear where the small rectangular piece of is on the bottom.
Yes exactly, if you look in the left foot well with the cvt cover installed you will see it blocks that left footwell a bit, just cut around the foam, not any more, the rest is structural there. that will increase the air out, which gets rid of the hot air, and belt dust as well.

Just picked up 850, this belt cover is a joke to get off, need to be better than that, or it will get a full mod delete, is there any trick to removing it or something we can cut off to make it much quicker..
What about all the engine covers, the big one from throttle body's to secondary.. Why is engine to shielded from airflow? Is this a noise compliance from factory or is needed with belt cover for air movement..
I'm use too having maximum air flow threw engine compartment with vents and holes.. This thing is like Fort Knox for air flow..
Anyone else have a look a like crack on bottom of bulkhead? Is this brp quality control or designed like that!! Should they be welded up!!

Can you post a picture of what you mean?
Also, are you saying to take out the foam and felt inside the cvt cover but leave the foam that's inside the side panel itself?
Thanks.

Take a look at the thread below and you will see the same thing. It’s not a crack and doesn’t need to be welded.

For getting off the clutch cover put your hand between the cover and flat piece by oil tank to get cover out of the notch and pull up and out. At first it was a real pain to get off, now no big deal.
So a question. How can the clutch suck cold air and exhaust hot air out the SAME opening.
this is funny...the doo cover is useless. Cat and poo have nothing , wide open and their clutch temps are alot cooler. They have not gone the route of noise suppression yet
It does not do that, your posts are mostly negative. Sorry that you don't get it. Cut it off if you believe that to be the best, I can't stop you from that. I have seen some of your other posts on Dootalk etc, you might be an awesome sledder but that does not translate into giving others advice that is not correct. It is the biggest issue with these forums lately, guys saying what they think is an issue or problems, which in fact has nothing to do with a particular issue. I know it comes from ego, but again it does not help the majority.
Once you have the cover off, you will see a a screen in the front that sits right behind the oil tank and there is some opening toward the inside (engine) in the same area where the belt draws the air in from under the hood (ribs on the outer side of the belt and rotation) and exhausts the air through the left foot well; some air stays in the guard and goes up over the secondary sheave to cool the belt and the secondary. There was an explanation for better cooling with the enclosed belt guard by skidoo when they first went to this type of design way back when.
Last year someone suggested putting a piece of sticky backed aluminum foil tape over the latch area on the front of the belt guard to help visualize the area and ease in the removal of the guard, it is easy after a couple of attempts.
I have cut off the bottom of the plastic at the back of the guard as suggested by Dave but not the part as suggested by Rasmussen, I believe the bottom off the belt guard rests against the belly pan to reduce movement and rattling etc on my 2017. JMO
