do you guys think that the engine braking on the 500 makes a big difference? if so a good difference or bad.


thanks again

 

Referring to my 2001 SP500 user's manual I don't see a word relative to EBS. I do however see an entire section relative to PVT (Polaris Variable Transmission). They seem to be referring to the same thing.

Any idea or am I missing something in my manual.

Thanks

Have a 2001 500HO with EBS. Would not buy annother machine without it. Can go down 45 degree slopes without using brake. Wife tried it, liked it, and was upset because her 2001 Sportsman 400 did not have. It does now. Reccomend any one interested - get it. [img]i/expressions/face-icon-small-happy.gif[/img]

 

Yes I agree.

What I am trying to find out is the difference , if any, between EBS and what is referred to in my manual as "PVT" (Polaris Variable Transmission) Both appear to be one and the same.

My manual refers to PVT but not to EBS.

Any Ideas ?

Thanks

 

yeah PVT is Polaris Variable Transmission and that aint EBS which is engine breaking system and dont hav e anything to do with PVT.....pvt just means you dont have to shift it like a manual..

 

Right - My 2001 SP500 has EBS but EBS is not metioned in my owners manual, PVT is. In fact the manual says quote "The PVT system rotates at hight speeds, creating large amounts of force on clutch components".

 

I guess I'm missing something. When I go to the Polaris website and look at the specs for the various machines, I fine the below information. Seems the EBS is a system withing the PVT. I was confused by the fact that the EBS is not listed in my owners manual. Now I understand: The PVT is the transmission and the EBS is a system within the transmission. Makes sense.

PVT is what makes the machine go. The mechanics are almost identicle to a Snowmobile transmision - increasing engine speed causes centrifical force to tighten front clutch on belt which forces the belt further out on the clutch thus changing rotation ratios between front and rear clutches.
EBS (which requires different front and rear clutches and belt) uses a similar process, only in reverse. When rear clutch starts to free wheel (ie: going down hill or rapid release of throtle) it tightens on the belt and keeps belt locked on both clutches and thus uses engine compression to slow machine down.
May not be exactly accurate in operation but okay in principle. [img]i/expressions/face-icon-small-wink.gif[/img]
