Rebuilding a rancilio z9 (220v) and rancilio MD 50

Hey guys,

I picked up a z9 this morning with the MD 50 grinder, they were used over 10 years ago in a coffee shop. I need some pointers on what to look at and what to be careful for, if anyone has done it before. Both are quite fifty, but the owner (friend of a friend) said that they worked great last time he tried. I have unmounted the metal, am planning to repaint. Will be posting pictures later

I rebuilt an old VFA a while back but not a Rancilio. I would start by dipping all the piping in descaler and taking the boiler in to get acid dipped. If you need any replacement parts cafeparts.com sells them all for a great price. Also make sure during the rebuild that you replace all of the gaskets, washers and screens.

Great find.
One of my ongoing projects is a 4 Group Z9.

Suggestions so far, from what I learned.

Take care of the parts, not everything is av. e.g. Boiler fill !!
I powdercoated everything. My paint guy suggests to go to the powdercoater, because it will be more durarble.
I avoided acid dripping I'd liked the factory NI look more that a CU look after acid dripping.
