If mine I'd change it at least every 50 hours. Couple ounces of fluid is a lot cheaper than the parts it lubricates!

 

Not on the 2001 it has two stronger metal cages in each locking front hub, much stronger then the newer single plastic cage in the locking front diff.

I hit the awd by mistake while the rear wheels where spinning and it held up where the single plastic roller cage would of blew into a thousand pieces.

But still never hit the AWD button on the fly unless both the front and rear wheels are spinning at the same speed.

Some people do not realized a Polaris is aways in 2wd even with the AWD engaged. Unless the rear wheels lose traction the ATV is always a 2wd.

 

good stuff fella's appreciate it

 

hence the phrase, "on demand awd"

 

The manual for my 06 Sportsman 450 say it is safe as long as your front wheels are moving(not just rear spinning) and you are under about 3,200 rpms.

 

even if the fronts are moving, you pretty much need the back wheels being the same speed to be safe. once you go above the rpm's/speed then the awd wants to kick back out.

 

My advice is to invest $5-10 in a Owner's Manual. It will give you the basics you need.

 

Its impossible to have the front wheels turning without the backs wheels turning. Unless you stand on the back brake and lock up the rear wheels only.
