Where can you get the plates from as this seems to the elusive item to find.
Does anyone know who made them originally, someone must be supplying them.

They're cleaning them, not replacing them I think..

SDP had them made I expect (Laminae or similar they tend to be called in German tech speak)

They can wear off the particular surface finish, and with severe failures, wear or warp even worse (I believe)

We shall see just how "hard" the facts are when I get my next email at work. Until Monday, Tchus!


I don't need hard facts 8) , I'm just curious if they are really as hard as you think :mrgreen:

Sorry Christian, I was being a little too careful with my information :oops:
Herr Weber says that you need very accurate weighing equipment. That's OK, we have laboratory scales accurate to 0.01g here in the workshop (ex-hospital). He assures my friend that all the information necessary to up the VC will be supplied in a pdf, which curiously is in English...The 100 vicosity fluid is reckoned to be a suitable replacement for road use - this is what they refer to "soft". They do have a second fluid for "hard" or "sport" VCs, but he recommends this only for hard offroad driving.
The starting point for a good vc rebuild starts with accurate weighing. If it's blown the seals out (lost fluid) or wrecked the plates, it is probably dead (he says) but 8 out of 10 should be fit to refurbish.
I wonder if the original fluid blend was to achieve a "multigrade" effect. After all, as the front diff warms up, so does the VC and this must affect it's performance characteristics. What are they like to drive in really cold conditions (Scottish winter/Norway) until it all gets up to working temperature? DO VC's last longer in the frozen North?

I would imagine it was almost certainly to get the correct viscosity, from two readily available 'stock' viscosities, by mixing pro-rata quantities

Karl, living in South Devon, you don't know what "really cold" means :lol:
PS you never mentioned you had a Tristar before... :rofl

:lol: Then again you were "only" visiting...good to see you're putting some mileage on it, now it's in your ownership.
Serously, I was wondering if VC's do last longer in colder climates....

I reckon keeping the oil level right is very important as thats how the VC gets rid of heat build up.

We need to drill and tap a hole for an oil temp sender, and see where the heat build up occurs, motorway or off road.

I prepared a document for the wiki of IG16" some years ago, but did't post it because of some missing information. I'll write a new revision with all my information I can give you.
I'll have it translated into English and will post it here. Please be patient, it will take some days because I'm busy at home at the moment.

I'll NOT tell you the viscosity, because I promised to keep it as a secret to the people who whispered me some numbers and told me some other details. You can call me old-fashioned, but I won't change this - trust must stay trust.

Some short information in the meantime:
- I have never heard of different viscos for different countries/different temperature - the spareparts number is always the same.
- the visco needs some temperature to work correct. I notice that in winter, when it's cold here.
- its more torture to the visco to drive on a highway than offroad
- sorry to tell you @silverbullet, that your hardfacts are not meeting the original details. They may work for users with a decoupler, but never ever can be compared to an original visco. The exact scale is ok, but just as long as you know exactly HOW MUCH of the ORIGINAL fluid should be filled in YOUR visco.

Greetings, Christian

That is why Weber said that if they have leaked, you are in trouble...I quite understand that your source of information needs to be kept happy - trust is indeed trust.
It's a pity, because I would like to give the information to everyone and blow the roof off this whole secrecy thing.
I would be happy to pick up just 10% of the work, knowing that I had built a good test rig and had happy customers.

I have 2 sources. One unfortunately left us some months ago, and the other is a good friend (he has direct connection to some VIPs :wink: ).
Sometimes it's very hard to keep a secret, but I promised.

VIP's? Mine are my wife, children, family and oldest friends.
There's nobody "important" in any hobby/scene, just useful individuals.
Sorry, but I don't do eliteism.
