well i was playing in the snow today and while in 2WD mode mine jumped into AWD.(only when the rear tires were spinning alot though.) It went in smoothly though so I just kept it in AWD. On normal ground it never did that. What does that mean? Whats wrong? Like I said it only did it when the rear tires were spinning alot faster than the fronts.

 

a few weeks ago there was alot of post on here about the awd issues and i think i read some thing about if the rear wheels spin past a sertin speed or so many time the awd will kick in to stop wheel spin....now dont quote me cause im not 100% sure about it

 

That's exactly what my ATP is doing. Anytime there is excessive rear wheel spin the front wheels engage. I was doing donuts in the snow when all of a sudden the fronts locked with the rears at speed and sent me rocketing off in whatever direction I was pointed at the time. I damn near drove up a tree. Later I found out that by putting the wrong kind of fluid in the front end when I changed the fluids out I had caused the rubber coating on the armature plate to swell or something, which causes the fronts too lock whenever you get fast rear wheel spin.
The damn owners manual is a little vauge on what type of fluid goes up front, they actually use two different names for the crap. Anywho I ended up putting the same fluid up front that I used in the tranny and that's NOT what it takes. Live and learn, I am just hoping theres no damage to the Hillard mechanisim, I really don't want to drop $400 or $500 into the thing right now...

I hear that. I know that definately have the correct fluid in mine though. (on demand hub fluid)

 

Sashton-my 04 700 did the same thing with donuts. Fronts would occasionally grab. Haven't noticed on my 06 or the 99. Never did any damage.

 

Good to know, Thanks

 

The only problems I have heard about on the Polaris AWD is the boots don't hold up. My brother has a 05 sportsman 600 and the front inner and outer boots have been replaced twice and the rear inner and outer once. Good thing he bought the extended warranty. Whatever bike you buy will have some problems. They all do. Just make sure you spend the extra money for the extended warranty. If you never use it then great but my brother has over 3,000 in repair bills from the dealer that he did not have to pay for because of the extended warranty.

 

Qball Thats the same way I F"d up the front end on my 02 700.Used the wrong fluid.And riding it like it was a sport atv.Polaris makes a great atv in my mind the best on the market but they well test your mechanical ability from time to time.

 

The reason the front wheels lock in when the rear tires are spinning real fast is that the Hillard clutch rollers "fly" out and lock in because of centrifugal force. The springs that hold the rollers disengaged can't hold the rollers back with that much tire speed difference.

The Hillard clutch "kinda" locks in when you are running 50-60 mph down the road also but the rear tires are turning faster or pushing the fronts.

Even if you were spinning the rear tires at that speed the front tires would lock in at a speed barely faster than the rear so there is no chance of damage to the clutch.

The way to keep this from damaging the drive parts is to not spin the rear tires only really...really fast.

 

Hmmmmm But I used to be able to spin the rears all day long without the fronts engaging. Before I put the wrong fluid in the front.

Oh and on the original topic of the post I haven't driven the Polaris 700 or the Grizz 660 but I have driven a King Quad. All in all it felt faster and more powerful than my wifes '05 Sportsman 500HO but not by the margin I would expect. The neat thing about it was the steering, the engineers at Suzi did their homework on that steering setup because it was almost effortless. Much lighter than either of my Polarises??? what's the pleural for polaris? Polari?
