Hi,

I'm using la Marzocco naked portafilters on mine and they fit altought I measured EBM:82mm

Don't know if they changed the group at some point, mine is from 85.

Hi Sam, nope unfortunately. A E61 portafilter is a no-fit...
The measurements:
EBM=82 mm
ID= 62 mm
KH= 6 mm
KL= 27 mm

Interesting!

The naked E61 portafilter I am using daily is:
EBM = 82.8
ID=61.7
KH=5.6
KL=26.6

I also have 2 other spouted portafilters from an actual E61 machine (San Remo Treviso) that fit. There must be different version of grouphead?

Also, the LM portafilter that I have (don't ask me how I end up with all these :oops: ) measures very similarly to the E61 handle, except that the KH is 6mm and KL 27.6mm.

I also have a Breville Dual Boiler portafilter that matches your dimension closely:

EBM=78.5
ID=62.2
KH=5.8
KL=24.9

That didn't fit my Aurora too well because the EBM is a tiny bit too short. It locks in but can pop off from the group under pressure.

The grouphead fitting it will be the same of an E-61 (although is not an E-61 looking one) and the suggested ones should be as mentioned,
at least for every catalog of the suppliers I'm looking at,
if so then your situation will be as for an E-61, the option of the different thickness grouphead gasket,
note also that a portafilter that is designed specifically for FAEMA it will have the wing thicker then other E-61, that could be the issue as well.
