The newer models come with this feature.

I am going to put a switch on the wire that grounds the ADC coil, so I can have AWD without ADC when I want to. Basically I don't want ADC unless I'm actually on a descent.

I tested this idea by disconnecting the ground wire from the ADC coil, and it works just fine. So now all I have to do is wire up a switch between the coil and the connector and all should be good.

I'll take pics as usual and write up a tutorial for anyone else that might want to do this.

 

since i dont have the opition like yours sheep was id the differnce you have when the adc is locking in vs not having it locked in. i really didnt check it either way on mine. ust wondering.

 

I can't wait to see pics with instructions....I would like to be able to disable it as well. I like it, but only for downhilling!

 

If it wasn't for snow plowing, I probably wouldn't bother with it. First of all, I plowed a whole year with my non-ADC non-EBS 500. It plows a lot better because it keeps it's momentum when you let off the gas. With the 800 (EBS and ADC) when plowing as soon as you let off the gas it wants to stop, this is due to 4-wheel braking. I suspect that some might just say not to let off the gas until you want to stop, but I find that it is simply a PITA having to deal with this braking when you don't really what to use it.

The AWD/ADC system being the way it is, and proven with my recent video of the front and rear wheels rotating at different rates, ADC is like a hyper automatic braking system. When it's not needed, it shouldn't be on in my opinion, and thats where the switch comes in. I believe that being able to have it off when you don't need it will save lots of wear and tear on the ADC system.

More later.............

 

You can deactivate the ADC but you can't turn off EBS. Engine Braking System. You'll still come to a stop, maybe a little farther if the rear tires are sliding.
You can ride around all the time with AWD/ADC on it will not hurt anything.

The only catch with the video is that as soon as the atv would move forward, the front and rear tires would be turning the same speed and the front wheel drive will override and instantly disengage.

sheepdogMSP8117,
Not trying to be a ***** *** but I just want to make sure everyone understands the way the AWD/ADC work.

 

yea im pretty sure he knows that. yea buddy i wasnt thinking of you plowing snow and i totally understand what you mean. thats why i asked YOU why because i figured you must have a pacific reason. thanks sheep.

Yep, I knew that. The front and rear wheels turning at a different rate while in AWD defintely explains why the ATV will come to a stop on its own while going down hill without using the brakes. Another way to show exactly how much braking effect the ADC system has, try this. When you're stopped on a downhill grade with no brakes on, just move the AWD switch to 2X4 and you'll start moving under EBS only.

That's a good point. But only if the rear wheels are not spinning. Makes one wonder why Polaris changed their switch to allow the operator to turn ADC off, had to have done that for a reason other than mere convenience.

This is the very thing I'm trying to accomplish as well. We're all here to help and learn from eachother. But I do have a fairly clear idear on how the AWD, ADC, and EBS systems work.

I'm just happy you didn't fill your post with exclamation points. LOL! [img]i/expressions/face-icon-small-wink.gif[/img]

1st the AWD coil is activated when the awd switch is on and 4wd engages when the rear tires slip 1/5 revolution and the override clutch wedges, correct?
2nd the ADC coil is activated when the switch is turned on only if throttle is closed, under 15 mph and in gear, correct?
What about the overide clutch in ADC? I understand that it wedges when the fronts are turning faster than the rears and then the ADC pump applies pressure to the ADC clutches, correct!?!
I've noticed that my atv will steer easy most of the way down except when its really steep and sliding, I figured that is the ADC system operating correctly and allowing the fronts to engage and disengage as needed just like the rear does.

I'm going to research this a little more and let you know what I find out. I have a new ADC front diff coming I can easily hook power up and see how it works.

I have EBS on my Srambler and I can wedge the front diff and decend steep hills but it is very hard to steer when it's wedged.
My X2 will steer easy if its not sliding.
I found this, don't know how accureate it may be:

There is a electromagnetic coil on the pinion that causes an armature plate splined to the pinion shaft to be attracted to a lobed plate. The lobed plate then runs at pinion speed. The lobe plate rotates and powers a small hydraulic pump that applies pressure to a piston that surrounds one of the output shafts. This piston presses against a muli-plate clutch. The clutch locks the two axle shfts together and locks the spool with the over running rollers to the output shaft. Since the front axle wants to run slightly faster than the rear, this causes the over running rollers to lock to the ring gear.

So if both front and rear have traction and are turning the same speed the over ride clutch should release, although the ADC pump is applying presure and locking the axles together, correct?

 

The ADC system doesn't overrun like the AWD system. I'll be busy doing family stuff for the next several hours, I might have more time tonight to better explain this or find the supporting documents.
