Restoring 2 Group Rancillio Z9
I've already posted on HB forum but I'm hoping someone here might be able to assist.
I'm currently in the process of restoring a Rancillio Z9 lever machine and I'm having issues dissasembling the spring assembly.
In particular, I'm having trouble removing the copper head at the bottom of the assembly which holds the rubber seals.
Does anyone have experience with these machines who could offer advice?
