EBS is essentially a one way bearing in the drive clutch. You can remove the cover and reach between the sheaves and rotate the bearing with your fingers, if it rotates both directions it is not EBS. If it rotates one direction only it's EBS. That's the simplest way to find out without driving it.

 

Thanks for the input appreciate it!

 

That's with the belt off too by the way.

 

The thing with ebs, is when things are failing, it gets MORE effective. If it engages with a bang when you hit a certain speed on deceleration, your secondary needs attention.

I realized mine had a problem when the ebs started to chirp the tires on pavement when it had decelerated to 20mph, and letting off the gas at anything under 20 was a head jerking and banging affair... Previous to that starting it was doing it at 10mph, but not as bad.
When I asked the dealership that sold me mine used why it jerked us forward with a bang when it hit 10mph on deceleration they lied to me and said "they all do that".
Turns out, there should be no jerking or banging on deceleration. With a new secondary clutch there is no jerking at all, just smooth deceleration from whatever speed to a stop on level ground or even slight downhill. If you aren't getting that, your secondary is messed up.
The one way bearing doesn't come into play all all till you have decelerated to 5mph or so.

 

this sounds like exactly whats happening. When my secondary exploded for the first time it started to hit the EBS way harder, like you said chirping tires or skidding on gravel. It usually doesnt act in a severe fashion until I am down to that 5 mph (my machine is in KPH ~10) but it is now very harsh. The one difference i notice this time is that I am not having any issues with shifting...well yet anyways. I will try and get the secondary looked at asap or do you think its best to just redo the clutches again?

Cheers,

 

He was wondering how to tell if it was EBS that's why I brought up the bearing. Yes if it's "banging" or there is severe jerking when off the throttle the secondary is at fault especially the helix and rollers.

 

Also to answer your very first question, all 2017 900 trail models came from the factory with ebs standard. So unless your first replacement secondary clutch was a non ebs model, you definitely have ebs.

 

thanks, that was exactly what I wanted to know!

 

Hi @CanadianLurch! Did you find a solution to this problem few years ago? Our rzr seems to have the same problem and no help from the local service… I would highly appreciate your response 🙂

 

Clutches were gone...soon learned these clutches self implode every 3500 miles no matter what I've done. High / low gear etc. I've got 14,000 miles on it now probably on clutch number 5 including testing a duraclutch. I now have 2014 rzr 900 xp clutches with Dalton clutch kits and hunterworks upgraded secondary in both of my rzr 900 trails. That being said I am about to swap a mother clutcher set onto my ranger as I can get the whole setup for like $700 for primary and secondary. Take a look at those

 

Ok, I highly appreciate your advice! Could you check the following clip (

), does it look familiar when the clutch is dead? Have you changed the belt every time when changing the clutch?
