Topic: Replacing an E61 Group Gasket (6 msgs / 161 lines)
1) From: Frank Cascarano
After two years I decided to change the E61 group gasket in my Andrea
Premium.  Although there are numerous posts on how to remove the gasket, I
removed mine fairly easily.  It is installing the new gasket that is causing
me problems.  I ordered three replacement gaskets and have tried them all.
The problem is that the new gaskets have a slightly larger diameter than the
groove they fit into (so they make a tight fit, I guess).  The old gasket
(after being installed for two years) is slightly smaller in diameter than
the new gaskets.  I assume this is to be expected.  As I push the new
gaskets into the groove, they pop out on one side.  If I push that side in,
the other side pops out.  If I force the portafilter into place and remove
it, the gasket pops out on one side.  I have tried while the machine is hot,
I've tried while cool.  I finally gave up and reinstalled the old gasket.
Any tips would be appreciated.

Soak the new gasket in hot water before attempting to install it. Install
smooth side up.

You mean just changing the dispersion screen, right? I think so, 
because I remember taking it out and having a helluva time reseating 
the filter handle in there again. I just can't remember exactly what 
I did to reinstall it. I remember wanting to take a clamp to it and 
using the coffee handle simply apply pressure until it would turn, 
but of course I might scatch the top of the group.  On another 
machine I actually used a little canola oil to grease it slightly, 
which worked but that was a different issue. Let me try to remember, 
or maybe someone else knows the answer - Tom

You might try putting the gasket in the freezer first.

Apply a little Petrol Gel Food Grade Grease to the gasket before installing.
Beneficial for ease of installation replacing all group gaskets not just E61
groups. Five buck 4oz tube will last a LONG time, as in likely a lifetime
home use:http://www.restaurantequipment.net/new/All-Points-Q-666-Food-Grade-Grease---4-Oz.-Tube-(All-Points-Item-32-1683)~178-Q-666.html
It is also sold by many espresso machine sources but I don't believe Tom
carries it.
This should also be used when replacing the E61 lever bushings and lube the
cams at the same time.

Thank you all for your suggestions.  I just discovered this note on the site
where I purchased the gaskets:
*"SEMI-COMMERCIAL MODEL USERS BEWARE!*
Models such as the Expobar, ECM Giotto and Isomac claim to have an E-61
group head, and for the most part they are, but we have found that the
outside diameter of these gaskets are too large, and recommend this other
gasket instead: XXX"
So, this appears to be a known problem and I'll let you know how the new
gasket works out.  I don't think this note was on the site when I purchased
the gaskets back in February.
