I recently started a restoration on a La Pavoni P/TRE 2 group 110v unit. While it is large, it is 110v, and has an internal pump. When I received it, it appeared to be in pretty decent shape. Missing a few small parts (including the portafilters) but nothing major that would make it unrestorable from a cost standpoint. When I started tearing into it I found some items that are concerning me.

The boiler sat in the unit crooked and only had a mount under one side. Initially I thought this was by design, but as I looked at it closer it appears to have pulled down on all the copper lines, either moving or bending them slightly. While I can't find many pictures of similar units, the ones I see don't appear to have a mount band strap on the plate side of the boiler. So now I'm not sure if it is supposed to have a mount on the plate side or not. The mount it has is simple, so making one will be trivial (if for no other reason than to support the boiler weight.) Any ideas what is supposed to be on that other side?

The unit was not drained and the Procon pump froze. The flat plate on the pump acted like a freeze plug and bulged out. I think this probably saved the pump as I don't see any cracks. I think it can be rebuilt. I'm hoping. $40 for a pump is OK. Any more will just add to my ever increasing parts list.

My biggest concern is the boiler. While it appears to be in decent shape (I have not pressure tested the HX yet), there are 2 aluminum shells or clamps that go around it, and sit on the other end of the boiler flange from the big copper end plate, and bolt to that plate. These 2 parts (I don't know what to call them, so I'll call them clamps) are heavily corroded, warped, and one is broken (you can see in the picture below.) I really don't think I could use either of them, and if I used one, I'd have to find an identical one as they overlap. Does anyone know a source for these? I have not seen any at the parts websites, but I have not contacted them either. If I have to make my own, I'll have to come up with something out of steel plate.

Overall, I think it is still restorable (at a reasonable cost.)

Comments, suggestions welcome! Here is a few pictures of the unit.

Those metal clasps hold the side of the boiler attached to the rest of the boiler, once you unscrew all of those bolts you can open up the boiler and descale it properly.

The problem is that the way it is now with that piece broken like that, it will not be water tight and will leak.

From the looks of that it is VERY possible that the heat exchanger inside is busted as well.

Your best bet right now is to open up the boiler (by unscrewing all of those bolts around the circumference) and taking a look

If the HX is intact, you may be able to weld the "clasp" back on (but it has to be perfectly straight to keep the thread orientation correct.

If the HX is burst, I hope you didn't pay too much for this big paper weight

I've pulled the boiler out and apart, and it appears to be in good shape. I don't see any damage around the HX tubes.

The metal clasps are toast, and they are aluminum anyway so I won't be welding them.

Is there a source for used parts for La Pavoni's anywhere?
