What I did do was to hold it very gingerly with a pair of vice grips, being very careful not to deform the pulley and then fix the vice grips with a screwdriver. It's not elegant, but it worked.

Yes, there's a special tool for that but vice-grips are just as good . . . in other words, whatever works!

The adjusting bolt was frozen and too delicate to muscle out, so I ground the bottom nib off and the VCF adjusting pin now appears to be fully extended.

Sorry, don't understand what you wrote . . .

The pin pushes on an internal 'switch' (clutch) when the bms is cold (ie no bend) and DISABLES the VFC (It's not "VCF" . . but VFC for "viscous fan clutch"!). When the bms reaches it's 'bend' temp (100C or more), the bms now is bent and this releases the pressure on the internal clutch causing silicone to flow and LOCK-UP the fan.
If you mean that you ADDED the bolt/nut as shown in MENU#20, then the answer is "yes", the VFC is fully engaged IF there is silicone in the VFC. If not it won't do anything.
You will KNOW that it is locked as soon as you start the car; the 'swooshing' from the fan will immediately alert your ears. It was because of the constant air-noise that I modified the method.
