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.
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
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.
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
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.
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
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
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
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
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
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
+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?
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.
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 ?
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
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 ...

My visco lok was the culprit on my 13 can am outlander 650 xmr. I installed a torq lok locker.

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.
Also because the viscous fluid lets the wheels move separately at slow speed and locks them up at high speed (due to fluid dynamics)
I wish there was a torsen diff available. The are awesome and have no clutch to worry about.

Thank you for this video, very interesting.

Yep. Would have to cut it in half; and possibly add another clutch plate or two to tighten things up in my own opinion.
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
When mine breaks I will just get a torq locker. 6K miles and still going strong.
torque lockers are great. i have some install vids that you will find more than usefull when the time comes

Halo locker makes a front diff locker

Good info about that visco clutching being separate from the gear oil. How long befor you split one of those cases, and video the inside of the visco?
thanks for the comment. i will get on the cutting the visc lok apart soon... stay tuned
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
I’ve been hearing they brake on driver left axel a lot ! Just broke mine matter fact !
When mine breaks I'll see if I can get some info on that.
yes sir thanks for watching
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
Check ur drive shaft sbefore reinstall new diff
Hi.I want to replace the gel in my viscoLoc . Tell me please, what should be the viscosity of the silicone gel

It was deemed defective and replaced under warranty.
My viscolock never worked. Purchased a new diff and it still wouldn't lock

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
+Canam Matt yes sir that would work the only down side i see with that is that it would not turn very good when in 2wd
+Earl Smith im not sure what you did. did you take any photos?
Can I just add the torq locker and that should Eliminate the visco?
When my vis-loc kicks in and tries to spin the 4th tire all it does is growl. its trying to turn it but it wont. Is it done?
sadly yes that growling noise is the sound of the visco lok slipping
+mudNwheels will I have to buy a whole front dif? and will this visco lock break and leave me stranded or will I be able to go in 2 wheel drive?
you should always have 2 wd actually 3wd
+mudNwheels thanks for your help man!

Hola,soy de México,mi Can am commander 1000,el diferencial delantero,solo hace fuerza una rueda,alguna ayuda para resolver ese problema 😵💫
hello your visco lock is bunt up we have a product to fix that and save the rest of your front diff. send us an email we can hook you up
@@mudNwheels ok, what's is your mail?thanks for the answer
Does it have like a primary tire that has torque,,, say like is the left tire have primary torque- the the right tire get grip. ????
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.
I have a question I got and p
07 outlander the front drive shaft and 4x4 will turn on but none of the tires will spin
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 ?
good info! Thanks....
this is why I ride a 15 Rubicon with a real locker that gives you true 4wd not 3wd
yes this is one of can ams week points but we have a ways ro make them better now. also i will put my 3wd can am up against your honda
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
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 ... ..
