Ps last line of the second paragraph.
Ps last line of the second paragraph.
I feel like I'm speaking a different language to you. I have no idea what you on about.
For me this is an ok explanation of a viscous coupling:
It doesn't even mention a difflock.
Jeez, all I did was ask what happens to the viscous coupling when I engage difflock and none of you has been able answer with anything but vitriol.

Cos you are dense and havent googled it like suggested you dont get it. The last line tells you wot ya need to know: both axles are turning at the same speed. Difflock.done.
ON A VEHICLE WITH A VCU THERE IS NO MECHANICAL DIFF LOCK.....
The Viscous unit by the method mentioned IS the difflock....when one axle turns faster than the other the VCU starts LOCKING UP to ensure both axles start turning at the same speed.....
I did not answer '...with vitriol...' I answered your question of how the VCU works....
Simples....
No, obviously you didn't answer with vitriol - this is your first post since I asked my question. Thanks for that.
I get that the viscous coupling will lock the axles together when there is a speed differential. In that case, the answer I had earlier is wrong - my rear wheels (or at least one of them) should have turned when my 2 front wheels were driven. No?
So then what happens when I engage difflock? Now, just to be sure we're talking about the same thing, I have taken some pictures:
What effect does moving that lever have, if any, on the viscous coupling?
I'm not asking what 4WD is or what the difference between a land rover and a range rover is, give a guy break FFS.

YOU ARE STUPID!!!!!!!!!!! AND THERE IS NO VISCOUS ON YOUR VEHICLE!!!!!!!!!!!!!!!!!God....No, obviously you didn't answer with vitriol - this is your first post since I asked my question. Thanks for that.

Yours won't have a VCU fitted as you have a mechnical Diff Lock....No, obviously you didn't answer with vitriol - this is your first post since I asked my question. Thanks for that.

With the Diff Lock Disengaged, your fron axle and rear axle will be able to turn at different speeds hence why on a rolling road, your front axle and prop can turn with no effect to the rear axle and prop....
If you had Diff Lock engaged by moving the lever to the left, when you turn the front wheels the rears will turn at the same speed as they are now locked thogether through the Diff Lock.
Vehicles with a VCU or if the Diff Lock is jammed on...should not be used on a 2 wheel rolling road as this will damage the Transfer Box as the rears won't be able to turn....as such braking tests should be carried out using a Force Gauge (can't remember the name) positioned on the footwell and then driven and braked on a quiet stretch of road....
If you have a later Classic , P38 or L322 which has the VCU or Torsen system....and your MoT tester tries to use a 2 wheel rolling road for a brake test....drag him out of the car, beat him with a broom handle then take your car to someone who knows what they are doing!
Thats the Hand Brake Drum that acts upon the Rear Propshaft...Thank you, Saint.V8. That was a very clear answer. And not a single childish insult in there! Double thanks!
I was under the impression that this was my VC:
So now I'm not sure what it actually is. Difflock mechanism?
YourMechanical Diff Lock is contained in the Transfer Box bolted to the Gearbox.
Even if yours had the VCU, the VCU is internal to the Transfer Box with no external indication at all....
OK thanks. I have a much better understanding now.
I had googled viscous coupling, as some users politely advised me to, and the images I got looked a lot like that handbrake drum.
viscous coupling - Google Search
That'll teach me for googling stuff.
Now, I must say that most of you have made me thoroughly sick with your intolerance and unpleasantness to a stranger who had the misfortune to ask a question that was obvious to you, but not to him.
So you'll be glad to hear I won't be back.
Or I might come back with a different user name and you'll be nice to me because you'll have no idea, eh, goon?

From those images, it is an easy mistake to make, but the Range Rovers VCU is internal to the Transfer Box with no external 'drum' to see...OK thanks. I have a much better understanding now.

I do hope your tirade has not been aimed at me, a I try to be as informative as possible (most of the time)....
PS: the VCU is Item no 4...

its a high possibility. Unless ya a dick.you'll be nice to me because you'll have no idea, eh, goon?
Absolutely not! I would hope that would be obvious from context!
As for the others, they have reacted exactly as I expected them to do. *chuckle*
so your not leaving then?

I have just read this whole thread and can see where the confusion has begun right at the beginning. This guy got a great description of how a VCU works but then a slip up up let him believe that he had one.

I'm surprised to see that a 93 plate RRC has a manual diff lock ? My 92 plate has the borge warner transfer box with VC. (factory 200 tdi) Was there an option when new ? or has our man got a conversion
