Thanks David and Dave for your suggestions. It has crossed my mind to pour boiling water over the remnants of the rotor arm to try and heat up the sleeve to expand it so the rotor arm can be removed. I do not think this area has any delicate electronic components, but I would like to check on this before I try this approach.
David I have tried to reply to your PM but received the following bounce back

Many thanks,

Unless you know for sure otherwise, it's safest to assume that all modern distributors have delicate components inside such as for example a Hall Effect sensor.

Also bear in mind the engine is at somewhere near 0C at the moment, 100C water from the kettle could easily cause a crack, whether immediate or the start of one so when it warms up - pop! Also if the heat-gun didn't shift it, i doubt boiling water would either, if anything because the plastic doesn't have the same sort of coefficient of expansion as the steel shaft it sits on, might even make it tighter!

The other option is a freezer spray on the end of the shaft. Give it a good long spray or several long ish bursts, wait a minute or so and then try shifting the plastic. Same idea but in reverse really.

Worth requesting to have your post count bumped.

I am pleased to say that our 440 is finally running again. It looks like the rotor arm or distributor cap were faulty. It was a battle to get the old rotor arm off. It was necessary to drill into the sleeve of the old rotor arm which eventually allowed a screw driver to crack/split the sleeve - see photo attached.
This is the first time I am pleased to replace a component with a metal sleeve by a plastic one !
Thanks to everyone for your assistance.
Cheers,
Martin

Default Distributor Cap removal

The cap on our Olive (440) is stuck on- the lower torx headed screw has got the thread chewed out and is not removable- any suggestions?
thanks
