How does the Polaris 4WD work
i beleive it kicks in when the rear wheels spin so much faster than the front wheels, i think like 1/4 a turn or something. i am not sure on exactly how much though. and no, the AWD isnt speed sensitive, it kicks on when the rears slip. also, you can turn the AWD on at any speed so long as your rear tires are not spinning and are moving the same rate as the fronts. hope this helps

How does the Polaris 4WD work
Hey, thanks alot for the tip.
I just got a 500 and this is not too clear in the Manual.
I was told by the previous owner (err....NOT a mechanically-inclined young man!) that the machine HAD to be stopped AND in neutral to engage the AWD, otherwise it could trash the tranny. Well, that did not make too much sense to me, since the button is huge and easy as hell to push accidentally (which my wife has done twice) and it gave me a heart attack, but did not seem to make a sound or affect anything.
So as long as you are not spinning the rears, say on ice or mud, and THEN engage the AWD you are OK?

Yeah, I found the Magic yellow button before I found my Owner's manual.

Originally posted by me:
As far as restrictions, the AWD will not engage when RPM is over 3500. When the switch for AWD is "On", you are really in 2WD until the rear wheels slip a little, then you're in AWD.
I know people said this, but just my 2 cents.
I am not very good at explaining things, but i will try a more basic explanation. There was i thread i was in awhile ago with a good detailed explanation, ill look for that next.
When you turn on the awd switch, you are not actually engaging the front wheels. You are really just giving them the ability to engage when needed.
The front axle turns 20% slower than the rear axle does while moving. So when you have traction, the front axle turns 20% slower than the front wheels.
When the back wheels lose traction, they begin to spin. THis causes the front axle to speed up as well. When the front axle "catches up" to the front wheels (which were turning faster until you started slipping and slowing down) the hubs engage and lock the wheel to the axle, giving 4wd. When traction is recovered, the pressure is taken off of the front wheels and they disengage. (Rarely they get stuck in, explaining the problem when the handlebars pull to one side sharply until you reverse, unjamming the hubs).
