I agree.
If the stock fan clutch setup was so good you wouldn't need to "tune-up" the blue hub clutch...
IMHO the blue hub is the finest clutch that I have ever worked on. The machining and fit are first class, they can be disassembled, refilled and the valve tuned, where most other clutches are mostly/completely pressed, swedged together, disposable.
They missed on the fluid spec for the US market, for our use. My guess is that they went with the thinnest fluid possible to make a quieter, smoother operating engine and for the fact that most are used as grocery getters. This isn't unprecedented, the later model Taco's came with a light clutch, if you complain about overheating and/or towing they change the clutch. IIRC one is green hub the other is orange, the only difference I can see between them is the fluid thickness and color of the hub paint.
The upside is that the blue hub is "tune-able", by simply changing to a thicker fluid, you have a very robust, effective, reliable and simple fan setup.
