iv nevr had problems with my 03 400 out lander my visco will lock instantly even be for the tires rotate iv never had problems with mine in mud but this winter when i barried it in a 8 foot snow drift the the left tire that was down the farthest was locked up and wouldnt turn

 

thanks for the replies, more curious than anything

 

I had the chance to use my viscous locker yesterday in Moab, on slickrock. We had a couple of sport quads with us that couldn't climb one of the rock ledges on a trail we were doing. I had to hook my Outlander to the sport quads with a tow strap, and tow them up the ledge. All four tires were making smoke, on solid rock. I've had no problems from the viscous locker on any of my Can Am ATVs.

 

They have gotten better. The newer can ams lock easier and are more true than the older models. Here's a video showing the year differences. They use a 2007- 08,then use a 2010 model. Along with a thundercat. This video is NOT intended to show who's is better,but to show how it works and the year differences. YouTube - ‪ARCTIC CAT Front Differential Lock and Can-am Visco-Lok‬‏

 

I couldn't watch the entire video but thanks for posting it.

I would still take the viscous over a manual locker. (and a CanAm over an AC )

I don't know about all of them but most lockers only work in low range and are rpm governed and I think thats a joke.

 

I believe both the Polaris and Can-Am systems can be switched to 4wd on the run and that both are not speed limited. I know I've had the X2 up over 50mph in the snow. No problems. Not sure what limits the machines with the button to lock the front end have.

 

I have both a cat 700 and can am 500. For extreme trail riding(out west) and hunting i use the cat. For fun,trail riding I ride the can am,unless my wife goes along then she rides it since its hers anyways. Im pretty sure the diff lock on the cat works in high gear as well.

 

Can-Am visco is functional all the time, even when vehicle doesn't move or run as it is operated by silicone based oil and left-right front tire revolution difference, not by switch nor limited by vehicle speed. Now that said, visco activation is by revolution difference and speed difference between front tires as on old models, if I spin the front tire with my hand and do it slowly, I can spin it all day long (I tried with my old and thought it was broken until I took it to sand pin and gave some gas)

I tried same with new 2011, one front wheel up and other side down on ground and while turning by hand, the tire on air didn't spin freely as the visco is already dragging it and beginning to lock, if I whacked the tire to spin it faster, visco locks up and wheel stops turning.

The main thing is that is requires constant steady power to keep the visco locked which means these machines requires a tad different riding style than ON-OFF front lockers.

On Can-Am's only operator controllable function is the 4x4 switch to switch between rear wheel drive to four wheel drive and back, even that works on any speed on low and high range.

 

My friends Suzuki is goverend when the front locker is locked, I b elieve that the others with manually locking front diffs are too with the exception of Polaris and CanAm.

Both of those ATVs will allow for the front tires to rotate at different speeds while cornering and manual lockers will not and that greatly affects steering.

I would like to have a viscous locker in my Rubicon.

 

A little long and boring, but a good video. Think the Visco could have done better with a little smother throttle. The guy was "on-offing" it too much. Think he was scared...

I really like the Visco QE in my Rene. I find it just as good as my old Polaris set up. In some ways better, because it doesn't do that annoying one hub locked steering pull thing when going from forward to revers sometimes
