until i have a moment to do something more formal, let this be your guide
the top & bottom sleeve o-rings (not gaskets! why did i write down gasket??!) are different sizes, slightly!
v-seals for piston are easy – just take a photo before you take your old seals off to give you a reference when you come to put the new seals on
element gasket easy – be sure to put some silicone grease behind it to stop it sticking (no one should need this one for years & years)
shower screen – obvious
portafilter to group seal – obvious, just ensure chamfered side goes up
seals for the backend of the flick valves – so you will have to unscrew the valve bodies carefully right up against the polished stainless face of the machine without scratching the stainless or loosening the pipe fittings on the back (take off the casing and grasp the pipe tightly in your hand to prevent this from happening – more instuction on fitting these seals soon
seals for the drivers – all fairly self explanatory
