Paul, the actual removal and replacement took a lot of force on the shaft. It
is a very tight fit.
It was definitely not comming off and the metal collar was in perfect shape.
The old one would only have come off at the bearing not the shaft. That was my
worry.
Also when the pump was off I checked as much as I could that the pump bearing
felt OK. If the pump goes I am pretty sure my fan will NOT come off. But then
that's on my car as only I know how good/bad a job etc. was done.
Maybe in a couple of years I'll go with the electric fan when I get around to
adding some more bhp. Also it was close to 8x more for the electric fan.
Also there's the view that some folks might want to keep the car as close to
the original as possible.

keep a close eye on any recently replaced fan clutch.
...stop and think for a moment.....
If you were able to press it on in place, why wouldn't
just a little wear on that tiny sliver of metal let it slip
off while being spun at high speed.
It happens. Ask any parts yard guy, how many
damaged radiators he's seen.
Don't for a moment believe that this is limited to LBC's.
When water pump bearings go, they go abruptly. I've had fans
with pulleys attached, end up in front the radiator after passing
through it. The bearing had literally cut through the shaft
in under 1000 miles.
