Hi guys, just thought id post a few photos of my recent cleaning expedition inside my new Cimbali grinder.
I have a couple of queries...
Firstly, what do the burrs look like (as in do they need replacing) as i dont really know what to look for?
Secondly...how do i re-calibrate that grind-setting wheel so all the settings i wrote down prior to disassembly are still accurate?
Anyway, hear goes.

Those burrs look a little blunt and there are lots od small "dings" on the front edge.
They look worse than mine when I stripped the grinder.....
And I replaced mine.... they will then last you for years!!
New burrs - new calibration!
Old burrs - you should have wound them down till they just touched and noted the reading.... after stripping reassemble.... wind them down and fix the scale in the same place.
But I suspect thats a bit late now!
Yeah well it didnt take very long so it was just an exploratory operation to see the state of things inside.
I dont have a new burr set and i want to use it in the meantime, so i need to recalibrate the current set.
In other news, im not sure what i did, but now the coffee isnt coming out of the chute. Ive poured about a handfull of beans in and i havent really got anything back out yet...
...uh oh...maybe i should have just left it.
Maybe the coffee grounds are just filling up the little holes and cracks etc... just thought that might happen :)Originally Posted by Zakal1 link=1163663883/15#15 date=1163670090
Adjust the grinder to a coarser and coarser grind until you start getting grounds out of it and then adjust it via pulling shots from there.
Hopefully the burrs arent locked together or hitting each other currently. Back the adjustment off some before turning the grinder on again.

Another thought. Silly question perhaps but is the slide at the bottom of the hopper in the open position? :-?

hehe yeah it was in the right position, but i think it was something even more stupid than that.
I pulled it apart again (well down to the burr-carrier or whatever its called) and had a poke around, and all looked okay so i put it back together, and i think what the problem was that it was set too coarse....waaayyy too coarse so there just wasnt enough beans in there to get a grind going...if it had have been even remotely close to a normal setting it would have been enough i think, but i think it was miles out.
Its getting a really coarse grind now and im just about out of beans. When its set real coarse, is it suppose to shoot of the chute like on a lawnmower? cos it was only sort of dribbling out neatly when it was set properly before i pulled it apart.
Ill have to head down to the supermarket tomorrow to get some beans that a crap enough to waste on adjusting teh grinder setting.
Yep, thats normal... and probably like a lot of cafes set their grind >:(Originally Posted by Zakal1 link=1163663883/15#19 date=1163684176
To save beans in future - when you reassemble wind the top burr down until it touches the bottom burr and then back off half a turn or so as a starting point.
Not sure what blunt burrs look like. although there is a comparison from the old v new in my rancillio grinder in this threadOriginally Posted by Zakal1 link=1163663883/0#0 date=1163663882
if you have a look at the close up of the old burr you will see that the cutting edges had rounded off. that was the only real difference I could see between the old and the new. however to touch the new burrs were sharp, you could probably cut yourself with them. whereas the old burrs were really dull, there was no way you could cut yourself with those.
Having said that I must say that Im not sure what if any difference it has made. mainly because I bought the grinder from an auction and it was filthy so I didnít want to put the coffee from that grinder through my machine. I intend to put the old ones back in at some stage to see if i can tell the difference, not sure if I will be able to notice any difference, once the grinder is set up properly. I suspect that the grind settings will be different between the old and the new though.
but at the end of the day, new burrs were only $50 from coffeeparts.com.au. I think they are $49 for your grinder. So I figured if I was going to the trouble to strip the grinder, I may as well put in new burrs and get what is effectively a new grinder.
If you get burrs from coffee parts you may as well get one of the pallo brushes at the same time (postage saving would be my justification) plus they have 20% off. they are great. but just buy the single brush. I bought the one with 3 replacement heads, and I doubt I will ever need them.
Yeah well my burrs definitely wernt THAT sharp, and as was noted earlier, they havea few dings in the blades...however i did cut myself on them while cleaning (cos they were pressed fairly firmly against my hand).
It may affect the consistency id say (because due to the dings it probably cant produce AS consistent a grind) but i can still grind fine enough to confuse the volumetrics on my machine, and to produce 1min+ shot times (hehe despite being totally undrinkable, it still amuses me it can take that long after all those months of pre-ground stuff coming out in 3seconds). Im not ready to do descaling etc on my machine, and therefore IF i choose to replace the burrs, ill do it as part of a bulk order from Coffee Parts. And like you say, at $49...replacing them would only put the total cost at $207 so its hardly worth worrying about.
Im also sort of holding back in disblelief at my pump having seemingly magically resurrected itself from the brink as i was anticipating having to replace that too.
So i guess in the meantime ill just make do with these burrs...i really dont think my pallete is anywhere near finely-tuned enough to be able to tell the difference between old-burr and new-burr grind consistency yet.
I will have to recalibrate the burrs though. At the moment grinding on setting 2 seems a bit silly hehe.
Searching back through the grinder post I found yours about the Cimbali Cadet grinders burr replacements.
Im considering buying an very old Cimbali Junior and just had some quick questions. *
How did the burr replacements go from Coffee Parts?
Do you still have the grinder and are you happy with it? *
Im wondering if a 12 year old grinder is too old? *
It looks exactly like the current Cimbali Junior on the Cimbali website.
