Group head shim for Sumbeam EM6910
Just thought i would share this information as many people have a Sunbeam EM6910 with a worn collar causing the portafilter to turn too far around or not even seal at all.
The ideal remedy is to replace the group collar however applying a small spacer (shim) under the blue group head seal may give you some more time on the worn group collar.
A shim can usually be made by tracing the group head seal onto a laminated card or other medium then cutting it out and making it fit but that's a fair bit of effort.
Coffee Parts sell a group head shim that is an exact fit for the EM6910 group head.
The shim part number is 700728 and is only around a dollar.
You will support a site sponsor and save yourself some time.
I've attached a photo of the shim in place and a well fitting group handle.
Cardboard works but it is a fair bit of mucking about to get the size right. For a buck why bother.
I cut my own out of PP sheeting. It took all of 5 minutes to measure, print a template and cut it. The main benefit was not having to wait a few days for it to arrive.
Be aware that a shimmed seal will have a larger gap between the puck and the shower screen, necessitating a higher dose. Also my collar has worn unevenly so the left side is tighter than the right.
Out of interest do they offer a custom postage price for this item? The item is 95 cents, but the cheapest shipping option is $7.95.

That is a problem. Maybe give them a call and see if they can put it in an envelope or something.

It's like browsing a hardware store......I only came in for a pack of screws, $150 later and a box full of stuff.......
Days later still didn't hear back from them. That said, found an eBay seller once more. All good.
I orders three of them from coffee parts, not the same as mentioned above. I think I got a 71x59x0.8mm. I needed two my group was so worn!! But I'm back at 6 0'clock!!!
My experience with them was good, I ordered a tamper also and they called to tell me it wasn't in stock to discuss options almost immediately.
