    I guess it just depends on the size.  But check the internal tank dimensions, as they all seem to vary.  This is the one I bought and it has worked fine.

    You can get non-food grade citric acid from a pool supply shop in 1kg containers for about $10-20?? If you are doing a full strip down it will be easy to wash it thoroughly anyway. Or you can go hardcore and get some hydrochloric. It is also good to use hotwater with the citric acid as it works better.

    I havent tried it for descalling, but I bought an ultrasonic cleaner from ebay for $200 that I use to clean the chain and casset on my bicycle.
    It is fantastic what it will clean with just water and some detergent. It will clean better with turps. So that could be an option to consder too.

    There werent really any tech manuals for these, there were some parts breakdowns but thats pretty much it

    These on coffeeparts are about the same as them

    Sorry

    I should have said a service manual, if there is such a thing. I like to know how the whole thing goes together. Im a manual kinda guy if you know what I mean. Own an Italian motorbike and lets just say that the manual has come in handy at times. Still love Italian machines....they have a life of their own, never boring

    Manual will be quite useless, what did you want to know?

    Thanks Tim,

    Unfortunately i have stuffed the fitting. Did what you said (quality spanner and all but they did not budge. It is still in the grouphead so will be having another attempt tonight with more heat. I am not too phased as I can get another fitting either made up or from Coffeeparts (thanks Borat) or get my brother to machine one up (hes a fitter & turner), but in Tassie. Its just slowing the re-build process and causing unnecessary agro. Will work on the heat exchangers after Ive sorted out the groupheads etc.

    Also does anyone know where I can get hold of a manual. Will try and get some photos up soon

    Cheers

    Mark

    If you can apply more heat directly to the head and use a qaulity spanner of the correct size (no shifters) but dont stress if you cant get them out just make sure when you put them in the citric solution that you turn them over to expel any air that may be trapped in the pipes.

    Once you have the heads off remove both of the heat exchangers, I use a piece of timber wedged in to wiggle them loose. descale these and fit new heat exchange seals, 2 per head

    Cheers Tim

    Re: La Cimbali M27 - Little water through groupheads

    Hi guys,

    Need some help again. have removed one the group heads and got the bell off easy with a little persuasion from a soft face. Am having trouble removing the copper pipe at the top of the group head. Looked at Borats post on the de-scale and he obviously got them out but mine seem super tight. Have applied some WD40 and a little heat but not budging and getting some rounding of the nuts. Help would be appreciated ie should I apply more heat, get out the stilsons etc. Have the head in a vice (carefully). There is also a plug with a hex key for removal but Borat didnt remove for the de-scale but should I do the same.


    Also what is the mixture for the citric acid. I got a 75g pack but from the sounds of it this might be small.

    Help would be greatly appreciated.

    Thanks tek,

    Am new here so learning my way with the posts and didnt see your reply before I started pulling the machine apart.  I now have the machine working to a point.  I thought it was a solenoid and have checked all those and in the process found two mesh filters which were completely blocked.  The one after the pressure regulator was in a bad state.  Ive cleaned and re-assembled and now have water at the groupheads.  I will be pulling the machine completely apart and doing some serious de-scaling as the machine is in need of some tlc.  

    Im having difficulty dismantling the groupheads as the chrome coupling is stuck tight to the brass head.  Any suggestions as to how to get it loose?

    I was not aware of the jets so will locate and see if they are blocked as well.  Ill try and get some photos up soon too.

    Cheers and thanks

    To remove the group head bells first remove the 3 11mm bolts then insert the group handle and push down on it

    Thanks Borat.

    Already saw your reco from a while back and it was a great help in getting me started on tracing the problem I had. Have bought some citric acid for de-scaling and have already had some parts off but at the moment its all back together.

    Ive also got a La Cimbali Junior Cadet grinder (up for a reco soon too) and I had no alignment problems when I had the group head off a couple of years back. Will post my progress over the next few weeks with the M27.

    Cheers

    Undo the bolts and with some pushing and swearing, the bell housing will come off. They are a tight fit though. Much easier to get off than to get back on.

    When refitting, I had a heap of trouble trying to get the bolt holes to all align at the same time. I ended up loosely fitting some of the bolts and then levering it back on from the opposite side...

    If you are taking the whole machine apart anyway, leave the bell housing on until youve taken the group head off. I found it easier to work with that way.

    Do a search for some of my old posts on a M27 resto I did a while back. There are lots of pictures and info, and it might save you from making some of the same mistakes I made....


    good luck.
