I heard from the dealer here yesterday that Polaris will have all wheel ebs in 07 but only on the X2--why i do not know and neither did he, if his info is even correct. We ride a lot in the mountains and the only complaint I have is no all wheel ebs on my 800 for going down tough hills. I want you engineers out there and/or you mechs who actually work on these things to tell me how we can convert these to give us true all wheel ebs on demand. I have looked at the wiring diagrams and understand the lay out of the front armature and coil in the front diff. I also understand that supplying a constant voltage to the coil for an extende period would burn up the armature and Hilliard. True? Not true? and if Polaris does have this on the 07 they must have solved the issue. The Grizzley now has it and I want it. Give it to me>[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

i'm not arguing, but just something to ponder... do those hills require any turning? If both of the front wheels are locked in 4wd so it is true 4wd, then turning the handlebars will be very difficult while descending.

have you tried using low gear while on a descent? Mine would just about lockup the rear tires and maintan 2-4 mph downhill on the hatfield trails. I think you could run an additional wire to the reverse override button and make the front wheels engage by holding that button-- just a thought.

 

Thanks for the reply. There is the rare turn occassionally and yes I have used low. When the surface is one that promotes wheel traction the ebs works pretty good. But when coming down hardpan, loose gravel or any other surface, which we have a lot of here as it is dry, where traction is limited the rear tire slippage can make for an interesting rodeo ride. The override button is a good idea or a switch either of which solves the method of engaging the awd but the question remains, why did Polaris not make such a system? Is there a problem with burning up the mechanism if engaged for a somewhat longer time or are they sacraficing this to prevent accidents due to difficult steering?? More ideas???

 

Come on now---someone else must have dealt with this issue and knows something to do about it. All suggestions happily received.

 

my best guess as to why polaris never did aw ebs is most people cannot turn the handlebars when AWD is engaged unless on very slick surfaces such as much or ice. If they had a front diff that was 3 1/2 wheel drive for downhill and awd for low traction enviroments, we'd all be happy. Lemme think on this some.... perhaps a pulsing system where the wheel alternate would be the best solution (since the EFI already have computers on board).

anyone else?
