Re: New to CS and enjoying the reading
The 700146 is 0.5mm thicker to take up slack space if the group and PF have worn to the point that the 700150 would allow the PF (with basket) to be pushed right across to the lock stop and still be loose.
To change the group seal, you need to remove the showerscreen (phillips head screw) and then remove the dispersion disc (2 x 3mm socket head bolts). Then the group seal can usually be pried out quite easily - in extreme cases, the best tip Ive heard is to screw 2 coarse threaded screws into the seal so it gets pushed out as the screws extend out the top and hit the group.
The easiest way to determine if you need the 700146 or 700150 is to remove your seal from the Coffee, measure the thickness with calipers and replace the Babys seal with it. If the PF locks OK, then you need that same thickness seal. If the PF is loose, then you need a thicker seal (there is a spacer for REALLY worn machines). I seriously doubt that a domestic machine should need the 700146.
If you swap the baskets from the Coffees PF to the Baby, does it still fall out? If so, the spring in the PF needs replacing - CoffeeParts have them too.
All the external parts (PF, seals, baskets) are interchangable between the 2 machines and can also be interchanged with commercial Gaggia machines.
