Rancilio S24 Portafilter Gasket replacement

Postby hudsterboy on Fri Apr 22, 2011 3:46 pm

Hi there,
About a year ago I picked up a used S24. I'm finally getting around to doing some work on it. The group leaks at the PF heavily during a pull and I figured it's the PF gasket. I purchased a replacement gasket and shower screen. I'm just not sure of the best way to get the old gasket out. I'm worried about prying it. I don't want to break anything. I guess I could cut it out?

I should also mention that I've looked at the other threads about gasket replacement for other machines. Should I assume the same applies to this one (with some degree of judgment).

All I have is a parts list (with diagrams) for reference, so I don't really know any gotchas.

Also, while I'm working on it, anything else I should do? I don't see a lot of scale. These things had water softeners.

You can put some screws in and then pull the gasket out by the screws. Don't go so deep that you gouge the metal.

Given what you have said regarding the leakage, I would remove the entire grouphead from the machine. Now I agree that this is "easier said than done" but it sure will make GH gasket replacement easier. As you can see from the parts diagram, there is one small o-ring that probably should be replaced if you go this route.
Skål,

I have had good luck in the past using a corkscrew to remove a very old and dry grouphead gasket. I carefully "screwed" it straight unto the gasket and then pulled it out. Just be careful when using it.

I ended up going the wood screw route, and it pretty much fell to pieces. Then I scrubbed the bejesus out of the group. It took me about an hour using joe glow and a couple of toothbrushes. I did a couple of back flushes too, then tried a shot. wow. narsty. But no leaks! Now I have to play around with this guy and try to get a decent shot out of it. I think I mainly have to play around with temp surfing.
