Posted Sat Feb 6, 2010, 8:43pm Subject: Gaggia Evolution wand mod using V3. Not pretty.
So, I finally got tired of my broken plastic POS steam wand on my Gaggia Evolution. I started looking around for a replacement and found all these links about a modification. The only problem is that none of the links seem to work. Maybe I missed a good mod post somewhere, but I couldn't find it. So here's what I did.
Tools you need. 2 small crescent wrenches for all the fittings. 1 6" P2 phillips screwdriver Pliers to remove valve knob. Wrap it with tape, dishtowel etc, so you don't scratch it.
Bought a Silvia V3 wand at http://www.espressoparts.com/R_1054N Went to Home Depot and purchased A-715 and A-776 in the brass section. picture #1 Removed top of machine. Removed coupling at steam valve. Unscrewed copper tube from steam wand. Bent copper tube to my liking. If I were to put this wand in the original spot, the length of the wand would put the tip on the counter, so I bent the tube so it would come out the side as shown in Picture #2. This puts everything up high. You may want something different. Remember to make it far enough from the valve so you don't burn your fingers. I used a 3/16" rat-tail file to file down through the side, then put the lid back on and filed so the cover would have the other 1/2 of the hole and I would have a guide. 1/2 in the side of the machine and 1/2 in the cover. Picture #3 Assembled the parts. Screw A-776 into the new wand using the white knuckle/ball washer provided with the wand. The direction the washer sits is pretty obvious. One end will also seat into the brass fitting. I would use good teflon tape for these two pieces, not the junk Home Depot sells. If that's all you can get, then use it. Do not over-tighten! I did it just enough so the wand is sturdy and can be positioned in any direction without flopping back down. Screw A-715 into A-776 and screw original copper tube onto A-715. I left the original o-ring inside the copper fitting because the parts seem to line up. Use crescent wrenches on original copper tube and A-776 to tighten A-715 between the two. Screw copper tube back onto steam valve. Put lid back on. Make steam several times to check for leaks.
Yes, it's ugly, but I got rid of the cracked Pannarello attachment.
Having looked at other Gaggia machines, I believe these pieces will work for others. Just remove you copper tube from the steam valve and go to Home Depot and try the parts listed.

Just looking at your fine work you did there on coffee geek...thinking about trying to do it with my Saeco Sirena that has a panarello wand...Right now I am just using the steam wand w/o the panarello sleeve part and its a 'tad' too short...did you notice any increase or decrease in your steam power with this new wand? I am just wondering if there would be a decrease given all the couplings possibly? Any info would be greatly appreciated.

So basically you are tightening straight onto the wand to keep it tight enough? I know that at least in the commercial Rancilio wands they have a spring and a rounded sort of washer that pushes the wand into the collar (well the o-ring in the collar) to keep the seal. This makes it so you can keep it much looser. I don't know if that works for your current setup if you even had one. But just a thought.
