850 Polaris with the New Arctic Cat TEAM Roller bearing Drive Clutch

911 cover will help unless there is previous damage.
Dan can make your new covers with the massive bushing like 911 cover?

As an addition to your weight concern, I was considering custom ordering a tungsten balancer ring thingy to add more weight to my ctec2 clutch. I agree with you about not enough weight.

What ever happened with this?
I saw the roller bearing on the Polaris ATV clutches and wondered why they didn't use them on the snowmobiles myself.

2022 Polaris will have a roller bearing drive clutch. Clutch looks like and is very much like the Polaris RZR turbo clutches..

it should come with a carbon cover

 

[volcano buster]

The only roller bearing I see in the RZR clutch is what appears to be a belt landing bearing (#10) for the idle position between the sheeves.

What is its overall purpose?

 

[DITCHBANGER]

Can run the belt deflection tight. Belt sits higher in secondary like starting in a lower gear without all the squealing.

Good thing they have those turbo clutches dialed in so they dont explode or anything...

That makes a lot of sense. Tightening up the belt deflection to just below the point where the track starts rolling at idle with the tail off the ground is a common approach; obviously, you can take that a lot further with a rolling sleeve. Any idea if you still set deflection using the straight-edge and ruler? Makes me wonder if there's any reason you couldn't just run it all the way out with the roller bearing...

We will work on it this summer!

Will the new clutch have the wide pin, RZR type weights?

I will measure, but the spider has Huge buttons rather than the SS sliding plastic of the RZR clutch..

so your putting a 3lb heavier clutch on the sled? i thought the idea was to lighten it up? Can someone shed some light on this

 

[Betterview]

A heavier clutch better matches the new lightweight crankshafts on todays new motors. It has to do with harmonics and engine and clutch longevity. True that a lighter clutch can give a little quicker rev response, but it will come at a reduced lifespan for both the engine and clutch. The P85 clutch is already very light and in many applications works better with the electric start drive ring attached.

But the Patriot does not have the porkchop lightweight cranks like the HO 800.

 

[Betterview]

Are you sure? I am rather certain the Patriot 850 snowmobile engine has the porkchop style crank.

New Lightweight Crankshaft
All-new design is strong and stiff while maintaining low inertia.

• Larger clutch taper design for durability and serviceability
  • High capacity bearing

Okay sorry, I must have been wrong. I got my info early when they released the motor and it was being compared to the 800HO which specifically said it was pork chop style. The 850 only was referred to as "light weight" but someone on here gave actual motor weights it is was definitely heavier. Likely just the beefier components.

Hey Hey Hey !!! Are you a mind reader ?

I just bought a New ZR 8000 Sno Pro last Wednesday, got the track studded and clutches machined up and installed a set of proto type adjustable weights with slick shift washers and a full driven set with full progressive machined Helix, slick shift washer.

Taking it on its maiden testing run this week end up in Northern Minnesota.

I will post some pics next week.

Oh ! Also installed heated seat and a few other cool things !

Two years ago I machined up a few sets of Proto-type adjustable weights and demo'ed a New M 8000 at the Big Horns and I absolutely Loved the Roller Drive clutch.... I have been testing different Cat Adjustable weights since 2018

This sled will be tested this week-end Normally aspirated and then it's getting fitted with Flat Lander Turbo system to test our new Cat / TEAM Turbo Adjustable weights

We are sneaking into the flatlander Pump Gas Turbo market.

We have been testing a Polaris Rush 800 Axys with pump gas at sea level with great success,

we have the Polaris flatlander set up dialed in..... this week end we are going to push the boost up 2 more pounds and see if our turbo head will handle 2 more pounds on pump gas.

At current boost on pump gas with 24 / 37 Gearing it will put the speedo on 122 to 124 mph with ease.

finally !!! Giving the 1000 Yamaha' s a whooping !! ??

Fun stuff !!

Next summer is going to be a fun Flatlander Turbo Year !!

Thanks, Dan

I dont know about you but I am jealous of what Dan does to make his living..... ok, back to another bullshit conference call! I'll check back later

it's a hard pass on taking off the best most consistent clutches in the snowmobile world to put a cat clutch on that a company that has been plagued with clutching problems for the las 15 years .no
freaking thanks
