La Pavoni Europiccola snap ring rust issue

Check the the piston seals are facing away from each other, so one seals for the up stroke and the other for the down. I pack the lube in between the 2 piston seals. Also lube the piston shaft so it slides well through your new seal. This is my pick for the likely source. Also check that the piston sleeve is smooth and no sediment or scale build up is present as the new piston seals might grip a little more?

I manged to break the remain piece in two with a pic tool. All seal in group head now replaced... yeah... works like it should....
Now when a pull a shot or is it push with this machine.. ;0
I get creaking sounds. I think im lacking lube somewhere...
I lubed the piston, and both the pins that hold the handle in place... not sure where the creaking is coming from...
might have to take it apart again and have a look.

thanks timmyOriginally posted by timmyjj21 View PostIf the ends have rusted, the rest of the ring may have as well. This can make it easier to extract if it breaks apart. Options include a dental pick to get behind the ends and try levering it out, or creating enough of a dent in the ends to get purchase with the circlip pliers. If really keen and cocky, you could use a Dremel cutting disc...but I wouldn't!
the rest of the clip does not look rusted at all.. ;(
I've tried a pick tool but no luck so far.
I don't like the idea of Dremel cutting disc.
I wonder if I can file it down in the centre and then try and bend it....

the new clip is below the broken off bits to show how much is left in the groove.
Here is the group head with the left over clip just visible.

i got the washer out first. Bent it up from behind, then was able to get it past the snap ring.Originally posted by samuellaw178 View PostAh, I see the problem. I had assumed the snap ring is out because you managed to get the 4-hole washer. A picture will definitely help, it really depends how much of the snap ring is left intact. Can be quite challenging if you have the ends broken and the body sits flush in the groove....
I am curious though how were you able to get the washer out without the snap ring out?
Then the gasket was easy to get out past the snap ring as well.

Sounds like you'll have to get a grip on what's left of it somehow and twist it out of the groove

Wonder if an old dental pick may do the job?Originally posted by databear View Post
There is no way to compress the ring to get it out. The grove is very thin so getting something in there to pull it out is not easy.
I'll try getting a pic tool or something.

Yes I want to replace it for sure... I have the parts ready to go..Originally posted by samuellaw178 View PostIt's a common issue. The fix is to replace it with a stainless C clip that doesn't rust
I just don't know how I am going to get the old one out, now that the ends of the ring have broken off and only the center bit remains in the grove.

Pics might help a little to get a diagnosis from the la Pav experts here, but I suspect Sam is right. Dig it out and then replace with a stainless equivalent ideally or get a like for like from a parts mob.
Alternatively you can take it in to get it done, will likely end up costing a few $$ though.

La Pavoni Europiccola snap ring rust issue
Hi
I have a pre millennium Europiccola and have taken the group head apart to replace the seals. All was going fine, I was able to remove the piston and shower screen from the group.
When I got to the section in the group where the piston seal is, the snap ring which holds in the four hole washer and the piston gasket was rusted.
The two ring sections at the end of the snap ring just broke off with no effort.
The rest of the snap ring is still there in the grove. I manged to get the four hole washer and the rubber gasket behind the washer out, but have no idea how I am now going to deal with this snap ring.
Any ideas would be great.
thanksTags: None
