Not at all.
Are the belt(s) off?
The single belt driving the water pump and alternator is still on.

That's right. There is free rotation of about ten degrees but the pulley,
including the outer rim, and bolt are moving together - there is no apparent
play either fore-and-aft or sideways. The pulley can be turned by hand
without turning the crank and at each 'end' of the free play, it comes up
against something solid.

It's hard to see if the lock tab is present but the head of the centre bolt
is definitely moving with the pulley.
Just FYI, this is a donor car which has been standing in a field for three
years or more. Six hours tinkering got it running again and at a 500 rpm
tickover, the (steel) fan - which is missing the rubber collars from its
mounting bolts, clatters like crazy. If the crank is making a noise, the fan
drowns it. Higher than tickover and up to 3,000 rpm, the engine runs as
sweetly as you could wish.
Hope this clarifies the problem.
