Gaggia Classic Rebuild
« on: 22/09/2016, 07:43 PM »
I've had a few projects on the go lately - clean and fix up a Boema single group I bought (in the hope of setting up a coffee cart), doserless conversion of my Compak K8 (mostly done by my mate), and a full refurb on a Gaggia Classic. The Gaggia is the only one that's fully completed so I thought I'd share. (The Compak is good enough to use but needs some finishing touches like a PF cradle).
I've rebuilt a Classic in the past. That was a long drawn out process as I was learning as I went. This time was quick and easy. I found this one listed on Facebook for cheap and thought it was worth a punt. It had been in storage for a couple of years with coffee still in the filter basket so it was a bit grubby and the whole area from the dispersion disc to the filter basket was in a bad way. The good news is that once I finally got all the gunky parts out and disassembled the machine I found that it was in good nick internally. I took the opportunity to give the boiler a manual descale while it was apart as well as give the whole machine a good scrub inside and out. I then rebuilt it with the following replacement parts and mods:

• Brand new brass dispersion disc
• New group gasket
• New shower screen
• All new seals and o-rings inside the unit
• Upgraded to a Sunbeam EM5900 steam wand with modified tip
• OPV set to about 10bar static pressure
• New water tank lid (the old one was missing)
• A couple of new bolts (just where needed due to corrosion)

I used it for a few weeks while my good machine was away at the service centre. It was working really well and making great coffee. The only thing not working is the light on the brew switch, which IMO is just a distraction anyway.

Here's a few pics:












I love coffee. It's as simple as that.
