Sheepdog, that is kind of what I was thinking. Since I can feel that ADC working it must be wearing on it
Also if it is there and working it might even effect the fuel economy of the bike on a trail ride.

I noticed on the 08 that they did have that additional switch to disengage the ADC.

I may look at following your steps on that mod if you post it when you are done.

As far as 2x4 vs AWD, I would think like in a rig like my Ranger, having it in 4x4 all the time widens turning radius, actually contributes to more trail erosion, and of course lowers fuel economy. And if you know how to drive a Posi or a good Limited slip diff there aren't too many "normal" trails you really need 4x4.

And with this bike feeling to essentially have no differential, rather a locked axle in the rear it only really needs that additional awd to keep traction in the bad stuff.

So like picking the right spot to cross a mud hole, plan ahead a little bit.

 

just like todays new awd cars the awd w/ adc or w/out works only when it senses the rear wheel slip so yes you can leave it lock in all the time w/ out harming. but like shepdog said for us who like the control of it i never ride w/ mine locked in and only put it in when ive gone as far as i can and then w/ the wheels stopped i then switch it in. when wheels are spinning, or sliding never lock it in as it was stated front end damage will happen.

 

BigBros,

We already know that the gear ratio for the front axle is 20% lower than the rear axle, meaning that the front wheels will turn only 8/10 of a revolution compared to one full revolution of the rear wheels. (or 4 full revolutions of the front for every 5 full revolutions of the rear).

RickCJ7 was able to speak with someone at Hilliard about the ADC fron differential. When AWD and ADC are on, there are clutch packs in the front differential that will attempt to lock up both the front axles upon decelleration. This will cause the ATV to slow down more aggressively than in 2X4/ EBS, due to the different gear ratios from front to back. The accelerated wear comes into play as the discs in the clutch pack fight to lock up the axles while the terrain/traction work against it. The clutch packs will continue to work until either the wheels come to a stop, or the ADC system is overridden/deactivated/turned off.

I've done about 20 hours of slowplowing this season, which we all know is repeated short stop-and-go runs in forward and reverse. Imagine this, that EVERY TIME I let off the gas, the ADC system has been activated. What happens when ADC is activated is this:

1) the ADC coil attracts an armature plate and a cam, which spin with the front differential input shaft and drive a pump,
2) the pump pressurizes fluid, which operates two pistons in the front differential,
3) the pistons squeeze against the clutch packs and attempt to lock the axles.

Being that I was operating at a max speed of 10 mph on flat ground, there was absolutely no need for ADC, but since there was no option to turn it off and still have AWD, it ended up working all that time, for all those cycles, for nothing. This undeniably causes excess wear, and IMO is the main reason Polaris made the new switches so ADC could be turned off with AWD still on.

I will soon have the best of both worlds.
