In which situations is a Viscous Coupling active?
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 […]
Are blue or black quad-rings better?
Answer: Totally equal, you should better pay attention to other things…
“Oil-sucking”- a design failure of the T3 VC
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 […]
Why does an old viscous coupling stink so miserably?
Anybody who already opened an old VC knows what I mean – the offensive smell of the deep black silicone fluid. But why does it stink so badly?
Testing of a “baking oven VC” #2
After having tested a so called baking oven VC months ago, I decided to test another one due to verification resasons. I got the baking oven VC from a german […]
VIDEO: How fast activates a CO2-VC?
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 […]
Progress from Austria: Co2-VC
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.
A warning to all VC drivers using the “baking oven” method
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. […]
