Subject: rebuilding a Nuova Simonelli Aurelia
 

I'm embarking on an ambitious rebuilding project to resuscitate a dead Aurelia three-head commercial machine.  I love challenges and learning new things, and I love coffee.  I realize that this is a long way from PIDing a Silvia, but I expect that I'll enjoy the challenge.

I'm just starting into the project and it's not even fully disassembled, but thinking ahead, I have some questions.  I've found parts and operating manuals and the like, but I can't find detailed specs on things like springs and o-rings.  I realize that I could just buy factory replacement parts, but I started to wonder about things like the springs in the steam controls.  I suspect that somewhere these springs were specified with a certain size and spring tension.  Likewise with the o-rings, I suspect that a temperature range, hardness, and critical size specs could also open other purchasing options.  Can anyone provide me with more detailed specs on springs, o-rings, and the like Nuova Simonelli machines - or point me in the right direction?  Yes I have searched the Internet with no success.

Also, I need some porta-filters.  I can easily find a Nuova Simonelli OEM replacement parts from a few sources, and a vendor or two on Amazon and Ebay, but I'm wondering if I'm missing any alternate sources.  I can't find many options.  What portafilters from other machines will fit the Aurelia?

Good luck with the project, it really isn't a lot harder than the PID/Sylvia mod, you need to take a lot of pictures though to remind you how everything was connected before you took the machine apart.

Parts are where you find them, much like used espresso machines. Used equipment dealers would be a good place to start if you have any in your town.
