Olympia Express Cremina 67 Rebuild

Muscles

That's putrid AM, hey show me your parts list before you order any... RM, cheers mate but all looking good so far. Now I can say I know what all the fuss is about with levers, there is a massive difference in the cup between the BDB and this baby, so many extra flavours

I think I'd be purging with Sulphuric acid.

I've been playing with temp and pressure on the Cremina using this as my guide: http://www.freshcoffeeshop.com/Coffee/en/espresso/olympia-cremina I have a pressure gague that connects to my steam wand and have been using my thermocouple and DMM. The DMM Temp reading when attached to boiler is 112 deg C while pressure gague is readin 0.85 bar. Can anyone tell me if I should expect a loss in pressure when measuring at the wand in stead of direct on the boiler? - My thoughts are that as long as I have no leaks the pressure throughout should be the same. Measuring the pressure via gague only at pre-rebuild settings showed a pressure reading of 0.5bar. The boiler now cycles a lot more often than it did before and the steam has a LOT more grunt to it. I'm liking the new steam wand and removable tip, but hard to tell if it is me, the tip or the pressure that is resulting in better texturing of the milk...

Boyle's law is the answer to the first part.. And even with a leak in the system = see Boyle's law

Cool thanks, just what I needed...

NOW remember the golden rule... IT's the cup that counts not the numbers.

yep, 2 + 2 =5 😉

Not harsh at all... teach a man to fish I say! :pan How are all your seals? Mine is so much smoother to use after the new seals were put in along with a decent amount of Dow 111.... Also, where did you buy yours? Craigs List? I don't imagine it was from CG or HB... or was it?!

Ooh go the 1200w breville, it would have to be 20% faster 😃

Go the 1200, pimp it good :thumb:

Great Stuff mate, sorry I missed your last reply... I find the machine too light as well and can tilt it back when raising the lever. Temp management I found wasn't really a problem but I was only pulling 2 shots at a time (set mine using the steam wand gauge from Orphan to 8.5bar) For such a small machine the steam is terrific! And I reckon the upgrade to the new wand is worth doing - I won't bother looking at a swivel wand (has been done before) as I want to keep factory parts on mine. After machine has cooled I move the lever back up for rest position and much prefer the Elektra double over the Olympia single and these are the only two baskets I've tried. (Elektra from Orphan - NOT COFFEEPARTS - wrong size from them) Dying to get my new sight glass in the post so I can continue on with the lever journey...

I should have mentioned that I was draining boiler completely after each use so handle up for me was no prob! Oh yeah, how small is the drip tray!! That and no cup warmer... saw a few custom mods for those but I don't have fabricating skills or the coin to make it happen...

Muscles

Oh and steaming much easier and quicker with newer tip :thumb:

Why would you drain after use ? What happened was that as pressure built up, with the handle up, the pathway is open. So hot water streams into the head and out into the PF and then out the two spouts....

Figured that was what happened 😉 I was only filling 2/3's before use, warming group, making two shots and steaming milk. After that was running most of the water through to clean out any fines from the piston cylinder/chamber. By this stage the boiler was approx 1/4 full so I would drain the last remnants and lift lever (looks much better when resting up)... I didn't like the idea of reheating the same water again as my lever use was days apart, most likely only on weekends for now anyway.

??? Lever Erectus. Is that where the lever becomes erect without any 3rd party involvement/stimulation? I did see that simply turning mine on one day literally turned it on.... Wasn't gonna say anything in case you all thought I was nuts :🙂 As for grind, I was using exact same grind as I do for BES900 with no probs. Not sure if that will help you at all... will take a photo tomorrow with a 10c piece for size reference - off to bed now.

I will never get it as the anti-vac valve takes care of false lever erectus and it only goes up when handled.

Ummmmmm.... hooooowwwlll?!?!? 🙁 ??? 😛

Going for a round 2 showdown against the 99 AM ? Heavyweight title fight :rofl: :rofl:

Oh yeah, absolutely drop around if you're free. Lacehim's up in Sunshine Beach up Coolum way.

I like photos Is there a likely chance that you will take some nice ones of the Cremina 67 and post them And leave Kelsey alone 😡 He is a nice bloke on P plates KK

Kelsey

No no, he's right. My latest roast wasn't up to snuff. And the Cremina certainly steams at much greater volume and power than the BZ99. Much fun was had by....well... me, at least. 😉 My wife came in afterwards and asked me if all this was some kind of elaborate ruse and if there was a lever machine hidden away in the garage somewhere. "No," I said. "That's AM's trick". :rofl: :rofl:

Muscles

Here you go AM, hope it gives an idea of grind size

Kelsey

Provided the only payment is your amusement at the fallout, I'm good with that. :laugh:
