I too had the same problem, did a spring swap, no change. Apparently their is a spacing that is measured between the magnetized plates. This is about .001" and was adjusted by my dealer. Running synthetic ATF helps too. More R&D for Polaris to look into, if it wasn't for us owners, how else would Polaris find out?

 

Hi polcat2

My 96 Scrambler has a bent outer shaft (wheel wobbles in 2wd) The dealer says you have to buy the whole assembly--axle,u-joint and cv. Did you have to buy all of that too or did you manage to buy just the outer cv & shaft? The dealer wants $179.00. Did you do any better?

No real new news here but I have the same problem with my left front hub on a 99 Scrambler 400. Recall anyone?

Hi, Sweetcorn. I have one more silly thing to try. A friend of mine worked on his 4wd system without a torque wrench, and we learned something. I suggested I go to my shop & get one, but he said we could just 'guess' it. Here is what we found out. If the axle nut isn't torqued properly, the 4wd will not work properly. If it is too tight, it grabs sometimes whenever it wants to, and if it is loose, it takes a long time to engage. Or was it too loose that made it grab whenever it wanted to. I wish I was taking notes!!! GROAN!!!
Anyway, to make a long story short, it could be caused by something as simple as improper torque on the axle nut. Try tightening or loosening it a quarter turn & see what happens. Otherwise, it is likely the magnet being too tight, which involves taking apart the whole darn thing to check the magnet poles. Take a straightege and compare the inner and outer poles. The outer pole is kind of a sleeve that can be moved in and out around the inner pole. You want it (the gap/clearance) to be from zero to one thousandth of an inch. Check 3 or 4 places around the edge to keep it as even as possible.
Hope this helps.
Hope this helps.

 

Once he unplugs the electric, and the wheel STILL engages while in two-wheel drive, the problem probably isn't the magnet/components. Something may be bent elsewhere...
Sweetcorn, check for bent parts(prop-shaft, outer-shaft, hub-assembly etc), then check wheel-bearing play. Engaging can be caused by the bearing being too tight.
Has this machine taken a hard hit?
I paid 250 for the complete half-shaft (I think) and you can buy just an outer shaft for around a hundred bucks..

Well I switched the hillard assembles to see if it was the clutch or magnet(if it was the clutch the other tire would do it) put it back togather and both tires worked fine. I held the throttle wide open and the fronts never engaged. So I am stumped as to what the problem was, I always use a torque wrench, so I do not think that was it. I guess I will keep an eye on it and see If it keeps working.

 

What did you torque it to ?

 

I think somehow you managed to set the clearance properly, sometimes a little hammer blow will do the same thing...
