How to change small pulley on kenwood KM020?

I need to replace the small drive pulley on my Kenwood Major Titanium Km020. Doesn't appear to have a pin so I'm presuming it's a push fit but it doesn't want to come off. Any ideas?

Apparently it's friction fit.......

Have you actually got the replacement part?

Can you see how it fits?
