seriously it dosnt work, the hillard is mechanically engaged, not electrical. besides if you lock the AWD system up and go on dry pavement, your going to grenade your differential

 

Gates,

OK I understand what you are saying because I thought the same thing before I talked to hilliard to find out exactly how the system worked and I thought a remote switch would lock the front end on my command. To prove that voltage is supplied anytime the switch is thrown disconnect the two wire connector going to the centralized hilliard and place a voltmeter in the connector toward the switch. turn the key or engine on and check the voltage after you throw the switch to awd. You will see approx 12v showing that voltage is going to the hilliard any time you throw the switch (unless the rpm is at 3100 or above in which case the computer prevents voltage from going through the switch until less than 3100 rpm). What that does is energize a coil that magnetically pulls a circular armature keyed to the roller cage and places the roller cage in a position for the rollers to grab the axles when it mechanically senses the 1/5 rear wheel spin. What you are hearing is the coil pulling the armature and cage into position not the rollers engaging the awd on the axles. In fact to answer your question of how do I think they check the voltage to the hilliard, the service manual employs the exact method I described to check to see that voltage is getting to the hilliard when diagnosing awd problems because voltage must be constantly supplied when the switch is thrown. If you want to verify this further talk to hillard---hilliard.com and then get their tech number.

 

Well I guess you learn something everyday. I did take apart a hillard clutch before and kind of know how it works. Just when you think you have something figured out someone proves you wrong. Does anyone know if some of the newer vehicles that are awd have a hillard type clutch in them. I'm just curious. Sorry for thinking I knew everything.

 

No need to apologize. We come to these forums to exchange information and ideas. I have even talked to tech departments at dealerships who were under the same impression. At least you were ready to accept the information unlike some others who will simply maintain their position no matter how wrong. I have learned tons of good info on here. My understanding of the operator lockable systems like on the grizz is that it uses an electric solenoid device to employ the locking mechanism. The BRP uses a fluid system ie Visco-lock to do the same. I'm sure there are some other make owners who would know more though.

 

hey gates59,wayout here,that was on the2001 magnum 500 rmk, they used the same front diff as bombarier,it's called visco lock,not the same thing,you are right..wayout,out....................

 

Huh?????

So I guess it wasn't just me whew

 

wow, i thought it was just me...

 

I first thought I needed a translator because of my inability to recognize a cogent thought from that post but since others have had the same problem I think I'm with you however I believe he has been dippin into the profits in the 'shine from the backyard vat.
