I'm asking this question for my uncle.....He has a 2007 Sportsman 500.

He explained to me how the AWD works....If you have the AWD "On"....the front hubs are not engaged until the rear wheels slip. is...rear wheels not traveling the same speed as the front.

He wants to know if there's a way to change something (possibly the wiring) so the hubs engage and stay engaged when the AWD switch is on regardless if the rear wheels are slipping.

Any info would be appreciated.

Thanks

 

dont the sportsman 800s have 2X4, AWD, and 4X4? if so you might be able to wire one of those onto your atv. i would like to find that out myself too.

 

i dont have mine yet, its on order, but from what ive read the rears hardly slip at all and its locked. keeping them locked all the time would make for harder steering from what ive read. i think they lock if the rear spins only 1/5 of a revolution more than the front, thats hardley anything.

 

yep, theres a youtube vid where a guy puts his in awd and just barely spins the back tires and the fronts engage, its a true 1/5 turn.

The front wheels are always engaged. The front diff is where the AWD clutches and roller bearing is located. With AWD on the awd clutches are activated and awd roller bearing wedges when 4wd is needed and releases when not needed, works similer to a Detriot Locker. The front wheels can rotate faster than the rear but never slower. This is whet makes the AWD system so nice.
also the front and rear diff are geared slightly differant to allow the roller bearing to disengage quicker.

No

No the AWD engages mechanically when its switched on. It has a roller bearing which wedges to lock the front axle. There is no way to lock this manually. If it does get damaged and stuck in 4wd you can't turn the atv and the driveline will bind.
Polaris AWD is true 4wd and very easy to use, although it is more complex than other brands.
Sorta like comparing a Wrangler 4wd system to the Grand Cherokee AWD system.

 

Disregard what I wrote.

 

Why would you want 4x4 on full time you would not be able to steer and use more fuel....the only way i would think of it is if i had power steering but still would not want it....

 

Two front wheels rotating at the same speed,even power steering would not help the control much.
