Only difference between the two is the bearing, the S has a one way bearing which is way less reliable.

You can however run the S belt on any 800, matter of fact the Gates belt we sell for all 800 is the same dimensionally as the S belt.

Maintenance would be the key to the bearing.

Could be the shaft it runs on is damaged now.

We carry a HD primary clutch from Team industries if this is something that interest you.

Todd,

Good points, but I've looked inside a new two-way bearing and a new one-way bearing, and I can't see anything obvious that would make one last longer than the other.

I'd also bet that with 12000 miles on a primary clutch, that probably doesn't have air filtering on the CVT inlet...the primary clutch is completely worn out!!

Pirate

 

Here is why I think the one way wears out faster, it does work and the other one just rolls.

So it stands to reason a one way could damage the shaft therefore the new bearing will get worn out faster.

In a rhino clutch there is a big one way bearing, if you put it in a wore out wet clutch where the surface is messed up the new bearing does not last long.

Todd

 

Todd,

You could be correct!

I got about 3 seasons out of my first one way bearing. And sadly, it was the whole clutch worn out due to the dust.

Pirate

 

Coming from you, someone I respect on this forum as being knowledgeable about clutching, I will take that as a compliment!!!

Todd

 

Todd,

You are more than welcome!

Tough thing for me is I keep my education growing at the school of hard knocks!!

Wish just once I could read about a problem before I learn the hard way!!

And a couple of hours a day on this forum hasn't gotten me ahead of the curve yet!!

But I keep trying!!!

Pirate

 

I totally understand that. I just try to solve issues that most people have with the average mods. We can do that pretty easily with the clutches and Dalton kits we offer. They cover most people. Sure there are mods and people we can't cover but they need something special.

Simply based on the business model we have, we stick to what provides the majority of owners a solution. The other would take a actual bring it in and let me fix it solution or something time consuming and custom.

the shaft of the clutch is fine, the service center at the dealer said that they are replacing the original 08 rzr $70.00 brng with the newer rzr $18.00 brng. but if you don't do your home work you would by the $70.00 brng. like I almost did, at that price I will have a few on hand

 

the new part # you want for the primary clutch brng 3514609

 

well I was so exited, got my parts today, sad to say the dealer was wrong on the new upgrade brng . the original is abouit 2" tall. the new is about 1 1/4" so I guess back to ordering the original, bummer I wanted to ride.:sad:

 

You know, I went to Polaris Parts | Polaris Accessories | ATV Parts | Ranger Parts | RZR Parts | PolarisPartsDealer.com PolarisPartsDealer.com Athens, OH 888-284-8219 and looked up that part number. Sure enough, its a Primary clutch bearing. But must be for an new machine.

So it goes. The clutch bearing is one part that I keep a spare around...just don't know when I'll need it, and my dealer stocks very few parts.

Just sayin'

Pirate

 

thanks, it is what it is, looks like I will have to do the same thing.

 

Now...if you want engine braking going down hill. Get the one-way bearing. It works great. No more having the clutches free-wheel going down a long slope.

The one-way bearing is PN 1520836

If you want the "Dual Sensing EBS" like quads have, then you need the EBS helix for the secondary clutch. I don't have my parts book handy...but if you're interested lemme know.

Pirate

 

You have used a one way bearing without using the EBS secondary?

 

I got the new shorter brng to work, (call me a hack if you want) since the new brng was only 1 1/4 long needs to be 2" I took some 3/4 masking tape and wrapped it around the old brng brass bushing side and cut it a lil extra and filed it flat. a lathe or band saw would be nice to use, and installed old brng none cut side towards the new brng with a fiber washer and another fiber washer on the cut side of the brng. the bushing I made doesn't need to spin it only hold the sheave centered. the new brng is almost like a wrist pin brng encased, has needle brngs almost wide as the brng. and I put a lil real expensive grease from ski doo just for needle brngs, $50.00 a small tube, they use it for the bottom ends of there motors, seems to work fine,

 

Well...you'll find out if it works.

I'd like to see pic, or sketch, of what you did to use the shorter bearing. Remember that clutch spins at engine RPM!!!

I was warned not to add grease to the bearing. Wonder if that was to assure the extra grease wouldn't be an avenue for dust to get into the bearing.

Let us know how your solutions works!

Pirate

 

it works fine, don't throw away your old bearing, it would be nice to have someone with a mill or lathe to just make a 3/4" brass bushing to make up for the shorter bearing, even the new brng has a small amount of grease from the factory, I will have to figure out how to make a sketch and post it, the org brng has a needle brng side and a bushing side, cut the bushing side about 3/4" buy an extra fiber washer that is used on the clutch so you will need three, (I always replace them) if someone made that bushing they would make some good money selling them, not sure how they bush the new clutches, looks like they only use one pic for all the years, and the brng they show next to this short on is the bushing that presses in the moving clutch sheave. same part # as mine shows on the 08 rzr.

 

Thank you so much for the tip. When I received the new bearing, I was super confused. Used your idea and it's working great. Unfortunately I taped off right on the line and cut, so mine was a blade shorter than it needed to be. There is a little extra play, but still plenty of landscape for the belt to rest on.
Two quick questions....
Can you buy a spacer? If so, is it part number 1 (3514492 BEARING-DU,1.75ID) when looking at the primary clutch schematic layout?

Also, what is the best way to get a primary clutch apart?
The first two that I removed using a clutch puller both came apart before the clutch even broke loose. I purchased another online, but the bearing is seized up and I can't for the life of me break the clutch loose.

Thanks

 

So is this thread saying that i can put a primary clutch from a 2008-2009 on my 2012?

 

2012 800 S did not come from factory with "one way bearing".

Oh sorry bout that. This is my first rzr. Just assumed it was the bearing bc it grinds when putting into gear( you kinda have to force it) and then when in gear it whines and moves without giving it gas. Just wondering if the 08-09 clutch will work bc for some reason theyre much cheaper and appear to be the same

 

Yes, an 08-09 clutch will work in a later model year. But if you are grinding and moving when putting into gear you have a different problem and a new clutch won't solve it. Hunterworks has described the problem and the solution here: https://www.hunterworks.com/grinding_into_gear_creeping
