Wow - that sounds like a great upgrade. I need to check that out to see if it would work on an 08. I think the clutches ie: primary and secondary, are different. we'll see.

Better engine braking? I think it works great as is. I can creep down most hills just fine, if I get going to slow and it disengages, just blip the throttle to reengage and it works real nice.

 

I don't know about you but I find when going down steep rough terrain it's difficult to hold the rpm at a point where the engine brake stays engaged. It's very annoying for me.

For that price that cannot be both clutches and a belt. Maybe the secondary and a belt. I can't see any reason to change the primary for EBS, that is all done in the secondary (helix).

 

Actually engine braking is mainly a function of the Primary(one -way bearing). On non-EBS primaries the the bearing(on the shaft and between the sheaves,where the belt rides when the primary is disengaged at idle) free spins both ways allowing the secondary to over speed the primary. On EBS primaries the bearing only spins one way like a sprag clutch,ie when the clutch is disengaged and the belt is riding on the bearing the secondary can spin slower than the primary but not faster(unless the belt is slipping on the bearing) resulting in engine braking.

I just sumbled on this thread as I was searching about EBS because I think my RZR4 would be more fun if it had true EBS, blipping the throttle on steep hils or having to ride the throttle or having it suddenly let loose is a PITA imo.
I'm thinking I might be able to get away with just replacing the non-braking bearing with a braking bearing but I need to do some more research. It probably won't be that simple with my luck.

This kit included both clutches and a belt, I have the clutches and belt they took out. I think they gave me a pretty good price for being a regular customer.

babits primary clutch is 358.00 alone no weights or springs

 

The clutch disengages much soon on the 2010 models than compared to the 2009's. I know I have both. On my 09 the clutch slows it down nicely and it will barely freewheel so you rarely have to use the brakes. My new 2010 freewheels way sooner and i have to use the brakes a lot more....

We had the same problem, I was always stopping to shift to low gear in the 2010, and my son would just keep going in high without using the brakes in the 09. We were looking for an early (pre October 2008) clutch when the dealer suggested this kit.

Yes that's one of the things I don't like about my 2010. I don't know why they messed with the clutch, the clutch on the 09's were great.

 

I have heard the engine braking is in the one way bearing in the primary, and I have heard it is in the helix in the secondary. Not really sure how it works, but I agree that it is a PITA riding without EBS on hilly trails. Let us know if changing the primary bearing to a one way works for you.

 

The helix may be different on an EBS set up,and I saw a few post here that some machines use the secondary only for EBS and some use the primary onely..well I am pretty confident that there is no such thing as a Polaris with secondary only true EBS. I think that some people think that keeping the RPMs up to keep the primary engaged is EBS...that is engine braking but is not how the "Engine Braking System" functions...EBS allows engine braking at idle with the primary sheaves disengaged from the belt via a "one way bearing".
I've read that you can put in a one way bearing from an '09 S(part # 1520836) and get engine braking at idle...but $130 is pretty steep just to get the part and learn it won't work. Knowing what I know about Polaris clutches it is believable. If someone wants to send me one I'll pull mine apart and see if it will work lol. Otherwise I'm going to continue researching before I drop that kind of money on an experiment.
Someone here probably knows for sure??

 

C'mon surely someone knows a fix for the downhill free wheeling pain in the arsss clutch that is on my 09 le, I can tolerate the going out of "gear" but it is rough as hell when it re-engages at the bottom of the hill. Does anyone have a parts list of needed items or should I look for a used sportsman "clutch"?

 

Does that clutch kit affect Top End.

I didnt check the price on babbits site because they dont have the little box where you can plug in a part number LIKE ALL THE OTHER SITES DO:rofl3: I sent a email to them a few times requesting one no reply...

Does this clutch kit fit on the 2010 RZR-S also?

Thanks

 

I'm going to look at putting the one way bearing out of an 09 S in mine when I pull it apart to put a clutch kit in it..need to have the parts in my hand to know if it will work. The one way primary bearing is the main piece responsible for engine braking at idle. At idle the primary sheaves release the belt and it drops down onto a bearing on the center shaft...a non-EBS 2 way bearing will let the belt overspeed the primary with no resistance...that gives you the freewheeling. The one-way EBS bearing is just that...a sprague clutch of sorts it only turns on the shaft one way...when the belt contacts the bearing and tries to overpseed the primary the bearing locks to the shaft and the belt can only go slower than the primary...but can not overspeed it without the belt slipping on the bearing surface. If the one-way out of the 09 S will fit then that should improve engine braking dramatically. About $120 or so to find out lol.

Sounds like a good plan I hope it does work, thanks for the description on how the braking works.

I think if that above kit will work on my 2010 I will just buy one and keep it in my spare parts box sooner or later the clutches will break or wear out chances of that happening at home are slim lol

Let us know how you make out.

 

Anyone try out the one way bearing yet?

 

Anybody know if the engine braking kit will work on my 2010 RZR-S ?

Any updates?

 

From what I can see when looking at online parts breakouts it looks like the '09 S Primary does have a one way sprag type needle bearing ... cost about $130.00. Vs the 2011 having a free spinning needle bearing in the Primary ... cost about $15.00 ...

BUT

The Secondary clutch looks wayyyy different 2009 vs 2011 .. So I would be tend to believe that both clutches would have to be changed for full EBS??

Check it out by searching the 2009 S, and 2011. I used PartShark.com - Motorcycle Parts, ATV Parts, UTV Parts, PWC Parts, Powersports Apparel, Motorcycle Accessories for OEM and Aftermarket.

Secondary helix design will determine how strong engine breaking is..one way bearing in the primary is what allows engine braking at idle (when the primary sheaves have released the belt) the work together...but the one way bearing is a must have for engine braking at idle...so you could have engine breaking at idle without an "EBS " helix but not without the one way bearing.

Cool

 

the 900 seems to have a good clutch set up or mines worn already it feels soft not like the 800s ,even at the slow speed where the 800 bounces your head like Wiplash im going with the DDP clutch kit as it comes wit hthe cut helix and adjustable weights so you can tune yor clutch to work better for YOU,ie faster or slower ups and downs

 

Yes the 900 set up has good manners..for the most part..nice smooth engagement and operation at low speeds, not jerky...some people dislike it's aggressive engine braking, especially at moderate to high speeds.. has an EBS helix, no one way though so it still freewheels near idle. The DDP kit uses a non-EBS helix... Still has some engine braking but doesnt feel like you hit the brakes everytime you let out at higher speeds like the stock set up does.

 

Does this kit come with the team roller secondary?

 

Anyone tried the one way bearing yet?? Several of us here in the Mt state need EBS!

 

Hey Hayseed,

I don't know for sure ... but from watching a John Deer Combine variable speed pully setup years ago .. there was very little to no belt grip on the face of the belt .. more on the edges of the belt ... so I don't think changing the center bearing to one way bearing would do much??

Then again .... I was going to start an Optimists club ..... but diden't think it would work?

Waiting on a response, anyone?

 

opcorn:

 

Not to hijack this thread but i'm the exacty opposite. I have an 08 and i want to do away with engine braking all together. When my primary bearing had to replaced i was pretty sure i installed a newer two way bearing hoping this would help, but its exactly the same.
So, is their anyway to get rid of it completely?

 

The center bearing only controls engine breaking at idle..when the primary is disengaged..when the primary is engage the engine breaking is a function of the secondary helix. If you want to reduce engine breaking across the board call Dale at Dirty DAWG Performance he can lead you in the right direction.

 

Does anyone know whther this kit would work on a 2011 RZRS?

If so, would the weights be the same, or could you switch the weights from the 2011 RZRS primary over to the primary on the kit?

 

I had a 09 RZRS, that supposedly had the one way bearing, I can tell you that it went into free wheel very quickly with any let off of gas. I put an EBS Helix in from Dirty Dog on the secondary and that gave me EBS all the was down to idle, could not get it to free wheel at all.

 

The helix controls your power from the secondary to the tranny, it also controls the shift out and backshift of the cvt and by this I mean where the belt rides on the secondary per rpm.... Withought having one in my hands to see and compare I can't say how it works.... I wish dirtydogs or epi would get on here and shine some light for us but then if they told us what we need to do we wouldn't be buying there helix right?

 

So true!

 

I have a 2012 rzr 4 800 is there a part or parts that I can get to have ebs?

 

Hey ToddR,
I have a 2011 RZR 800 with EPS, (eps don't matter but just wanted to brag) that I swapped out the primary clutch roller bearing with a one way and it did NOT give me engine Braking.

To get the Engine braking you will need to order the secondary clutch assembly with the proper helix in it. Now be careful, because I noticed that some of the 800 Sportsman ATV's have a Left handed thread bolt to hold the primary on ... and my RZR has a right handed thread bolt .. and sure enough the engine's rotate in the oppsite direction's ATV vs RZR .. who woulda thunk!!

Possibly a primary and secondary from a 2010 RZR would do the trick?
