Subject: Removing a group head seal
Is there any good way of removing a group head seal for replacement
without ripping it out? Like maybe trying to slide a thin
screwdriver all the way around the edge to loosen it up? I suppose
what I'm asking is that if most people have tried that and found it
doesn't work, I may as well not waste the time trying it myself.

The Gaggia technicians, (Master Baristas all - it
says so on their aprons!), around here have a couple
or so of self-tapping screws that are driven deep
enough into the old seal to hold, but not so deeply
driven as to penetrate to the metal underneath.

A gentle tugging on the embedded screws with a pair
of pliers usually has the old seal out within seconds.

No need to keep the old seal pristine - it's only fit
for the rubbish bin - or for use in a circus goblin's
hoopla-stall...

Warning: Do not do this immediately prior to a visit
to the Dentist. You may arrive either as a
nervous wreck, or a gibbering blob of over-
caffeinated humanity.. ;'))

A thin screw seems like a quick approach to getting it done. Harbor
Freight sells a 4-pack inspection toolkit for a nickel or three
dollars. Four stiff steel, variously angled picks that look like
oversized dentist tools. Pretty good for all sorts of things habitual
tool collectors do.

have a new one on hand. the old one will not be reuseable. so go for
it.

and as Dan sez, don't damage the metal.

I would use an old table knife to loosen and pry it out, a screwdrive can leave
dings in the brass. Another way is to screw a sheet metal screw into the
gasket, then use a pair of pliers to pull on the screw. Finally, I've heard of
people using an awl to punch into the gasket at an angle and then pull the
gasket out.
