VC (viscous coupling) rebuild videos

A German site showing videos of a viscous coupling rebuild!

Interesting stuff. I wonder if I could attempt this on the VC that came off my G60, which had obviously leaked out a lot of its oil.

Thats interesting, I wonder where they got the VC fluid from?

Well, in the video that he describes the materials needed for the rebuild, he mentions that he ordered the Silicone Oil from “Reiff Gmbh”

http://www.reiff-tp.de

Here is the page in their webshop that lists the silicone oils that they offer.

The silicone oil is made by “Wacker”, according to Reiff’s site. Let me do a little searching for a firm that sells the correct viscosity in small quantities, as it seems that Reiff only sells the 100,000 viscosity oil in 25kg pails, at 700+ Euro a pail. [xx(]

(Having German as a second language is useful sometimes.) []

Would it be worth doing a group buy perhaps? I’d be into it for sure. How much liquid does one VC need? At say 500g (no idea if this is correct) we’d need 50 people to come in at 28 euro each. I’d happily pay up to 40 euro for a portion. Could work out profitably for the person doing the portioning.

this is interesting

group buy could be great, but 50 people is a bit much i guess, we’re a small crew here

does this have any effect on the speed of the VC lock? is this gooey oil uprated or stock?

[86 Syncro]

According to the video, that is the correct oil viscosity for the VC, I don’t think that going with a different viscosity oil would do anything except make the VC not work properly.

Found one selling it in 500g tubs. [8D]

Wow, brilliant!

A Twix goes to whoever on here is the first to post their VC rebuild pictures. []

[Housey]

hmm. do we know exactly how much is needed? or is that something one simply have to figure out of its own?

(weigh the with internals before cleaning, then reweigh it cleaned to figure out how much weight it has lost during cleaning?)

[alexisblades]

I’m sure I’ve read somewhere that it needs to be filled less than 100% full, to allow for expansion, and avoid overheating the fluid. I’ll have a look for the info as I’m sure I’ve saved it somewhere.

[86 Syncro]

according to the link at the top of the page, it’s filled with 278g of oil.

[Housey]

yes, but thats the T3 VC, are the “newer” ones the same?
