Meanwhile it’s common, that the splines of the VC housing are a weak point and often worn out. Effects of worn splines are not serious in the first place (except […]
You may wonder why we started to offer a special VC-setup for stronger engines (TDI, Subaru…). What looks like a sophisticated marketing strategy was actually born out of necessity: We […]
As recently requests for overhauling the T4 viscous coupling are piling up, we want to give you a short overview, what we are currently working on and what the main […]
As we mentioned in the last section of this blog article already, a working viscous coupling will always relieve the gear box from a certain amount of load – even […]
Inquiries like this are quite common, since the intended functioning of a viscous coupling often could not be experienced.
The other day I could examine another tiny part about the “oil-sucking” issue. My understanding is, that it’s a design failure, where the extrem high thermal expansion of the silicon […]
In the last weeks I got a few inquiries regarding due to the activation-time of a viscous-coupling. Typical questions looked like these: How fast activates a working VC? My VC […]
After a bunch of inquiries on how to remove a VC, we decided to document the process of replacing a broken VC. The background for this approach is the official […]
After improving the Viscous-Coupling of the T3-Synro with a special valve and solving the oil-sucking-problem I was thinking about how to make our VC even better.
In order to test the accuracy of the baking oven method for overhauling viscous couplings, I ran an extensive test session on one of these units on the test rig. […]
