Clutch disassembly

[Phil C]

I've done this before, but can't remember how. Maybe it's an age thing. I've got the (1965 B40F) clutch on the bench. How do I get the clutch centre out of the chainwheel? (I've bought a new chainwheel and need to swap it.). Thanks in advance.  Phil

Tap it through with a hide mallet being careful not to loose the rollers.
