It's a viscous coupling. The viscosity of that gloop sealed inside there is affected by the heat created by the friction when there is a difference in the speed of the 2 sides of the friction plates. The gloop turns to a heavy jelly which acts as a binder to lock the plates together. soon as the friction goes, it starts to return to the previous state.
+Derek Burns I read up on viscous fluid and if its overheated for too long it basically turns rock hard, in turn ruining the fluid and now you get a full on locked diff
It's my understanding that they are called a visco lock because the fluid heats rapidly from the friction between the clutch discs during wheel spin and actually expands enough to cause lockup. I have a Subaru Outback with a viscous rear and mid diff and thats kinda how Subaru explains it. I'm sure it''s a little more technical than that but I think that is the basic jist of it.
Do you have an older visco-loc unit to inspect? They are bolted together instead of welded together. Also, FYI that you probably already know about, there are a couple of guys converting the visco-lok to a true electric locking differential and calling it the Halo Locker. Something about using a GM 4x4 actuator to switch between locked and open with no limited slip in open mode.
That heavy viscous oil under the seal I wonder if it has the same effect as my RC car the heavier you go the more the diff locks up the lighter you go "weight of viscous oil" the more it free wheels.
So it’s a open differential that provides power to both front wheels and when one happens to spin it provides the same power to both wheels. Don’t know when it would be 3 wheel drive
2012 commander 1000 my machine was pulling me all over the place in 4x4 kept lining it up still pulling canam said I need to change visco lock well I guess the tires need to be toenailed out not in and it works like a dream my bike is in very mint condition 8000 miles but I drive it to work everyday only snap ring for junk ass gorilla axles only problem I've had.
I've been have a issue with my Visco lock my Maverick will steer to the left really hard when the 4x4 is on I have a 2015 maverick max any ideas what the problem could be Some times 4x4 works other times the left wheel will never spin
yes you are right i have cut a couple of these apart the only real difference that i can tell between the qe and the old no qe is is the the qe has a couple more plates
+AULTimate OUTDOORS I know you put some miles on you can am I'm thinking really hard about getting one now that I cant find anyone in my stat that has or will get the highlifter for me I have had Polaris forever and awd is awesome I'm nervous about this front diff style when its working does it really work as gd and how many mile do you have on the front diff now that you have to replace it?
Good video,,, have you had any problem with your key not being recognized Ii only Good video,,, have you had any problem with your key not being not recognized
I'm from Brazil and I have a can outlander max max 2015 2015 it is noisy in visc lock in heavy situation I would like to know I can use 85w140 gl5 mineral lsd to try to reduce the noise differential 705401511
thanks to mudnwheels for the vids, and special thanks to ffrostking if I can find a halo, the only real complaint I've had about my xmr 1000 so far (she's still low km) is the lack of full lock up.
Never had a problem with mine rear diff I’ve had problems replaced mine at 300 k and again now at 5500 k I’m rebuilding it my self bought new gears waiting for them to come in not sure about the shims tho can am told me service said not to put anymore shims but the mechanic told me to put more shims will last longer and make less noise my rear diff always howls since new it’s a g 2 xmr
No. Problem is one wheel has to actually spin.. in the air before you are locked. In the needed situations you literally stop your forward progress while it "spins up" You loose all momentum.
On my stock 2015 Outty 800, I had it in 4WD and spinning in the mud, only 1 front tire was spinning. The visco never locked, but it made a very strange noise. It only happened once, I wish I knew why it did that.
The locker is activated by the right front wheel. If the left is spinning the right one won't engage. The right one is the "driving" factor of locking the front diff
Hey wonder what would happen if you weld the spider gears like the drag racers do it should be locked and you wouldn't have to worry about the visco lock engaging and you would have true 4wd
that sounds like the clutches in the visco are shot. please send me an email to mudnwheels@gmail.com we have a new product launching very soon that will take care of this issue and is a very affordable solution
I have the same problem but only right front tire turn the left side don't move unless manually locking the front diff My machine it's 2021 Outlander 1000 xmr this same "fix u mentioned work on my ?
My crown and pinion ..i thought it was visco ..its not . U sell any front diff parts like the crown and pinion.. clear as day in 4x4 on gas then off u can hear .on off gas clunk clunk ....and only in 4x4 ...go into forward drive from neutral clunk same into reverse ... .. Need to check my gear set ...
I get that you need power in skeg but I still think can ams are weak besides the motor. the motors are really good but everything else is just poor quality
I've worked on all machines, we are the most popular area in manitoba for riding. the 1 thing everyone complains about there can am is the time it takes to lock up. and climbing a small log is a chore even with a newer QE model
I have a 2018 Mav Trail 1000 dps. It will not seriously rock climb here in the West Moab, Rincon, Choke Cherry Rock Garden New Mexico... period! I talked to Halo yesterday and they aren't sure that there is room for the "actuator" in that machine, but it will fit in the housing. I'm going to find out asap even if I have to drive to Mo. Machine is excellent overall... but useless for rock crawling. My 2010 RZR does better and my Wildcat Trail with full locker eats up the hard stuff. Shame on Cam-Am
