Surprised it's a Wipac rotor not a Lucas but that's an incidental. The rotor itself is keyed to the shaft and once the nut is removed using the method described by Rob C it should just slide off. Just take note of how it's on there with regards to the spacers before removing it.

Thanks Primary chain still on I have tried in gear brakes on heating it bashing it after 58 years it is not going to give up easily. I might just try leaving the Wipac rotor on and use the new Lucas stator but will talk to Lucas tomorrow before I try that.
