Measure from the top edge of the OPV (with the screw removed!) to the top of the adjustment screw with a vernier gauge (Use the depth gauge on the bottom of the vernier) Make this depth 11.5mm. Y

OPV Adjustment for the Gaggia Classic   1. You will need a pressure gauge that has been modified to fit the bottom of the standard domestic Gaggia portafilter. (fig a)     This assembly cost

AndyL, thank you for posting this guide and thank you to those of you who similarly maxed out the pressure gauge and posted about it - my own pressure gauge did exactly the same thing when I adjusted

Just about to send mine to Ronsil. Maybe he could send to you when he's done?

 

Happy to pass it on if required. Let carbonkid85 know & PM me your address.

Hi Ronsil,

 

I'm new to the forum (unfortunately it won't let me PM you until 5 posts).

Any chance you could send me the gauge next?

Can e-mail you details/paypal postage etc.

 

Many Thanks

 

Andy

Thanks Ron,

 

Carbonkid85, please would it be ok for Ron to post onto me once he's finished?

 

Thanks

Andy

 

 

No problem but I don't have it yet. Should be here within a couple of days.

 

Clear it first with 'carbonkid85' so he can keep tabs where it is.

Received the gauge today. When you can PM me (+5 posts) your address I'll probably get it away to you by next weekend

 

The gadget is very light & I'm happy with a couple of 1st. class stamps. I'll give you my address when I hear from you.

Have now passed on the gauge lent by carbonkid85, many thanks.

 

My first reading on the Classic was 12.5 (probably 11.5 actual). I reduced this to 10.0 which I hope will be 9.0 actual. Much better pours at this pressure with more crema & flavour.

 

Now having completed the changeover of the steam wand, a good descale, throwing out the supplied basket & restricter & reduced the pressure my son in law, whose Machine it is, is in coffee heaven with results he is now achieving.

I didn't realise one was going around again. I'd like to borrow it at some point, but I don't want to jump the queue, so if anyone is waiting.....

Aphelion, if nobody else wants it, you could send it straight to me, saves somebody somewhere paying unnecessary postage, unless ronsil needs it again first?
