Lambro boiler pressure gauge broken

Postby NelisB on Fri Mar 04, 2011 3:05 pm

Hi all,

since last sunday I have my Lambro going and it's great. Only the pressure gauge is broken. I have tried to find one at the spare parts suppliers, but couldn't find this model.

Does anyone have one for sale or knows where to find one? Or can I get it fixed?

Thanks,
Niels

If you like email me the specs and I see what I can find for you,
it will not have the original face plate but perhaps a white/cream one

Nearest match i could find was the E61 original gauge, not sure if it would fit, but it looks similar.You can have them re-built, but its not cheap.I was quoted $400NZD (roughly 200 Euro)

Niels, before you go and buy a new gauge, if you're handy, you could try the following;
Remove the cover with the glass, after removing the cover and glass see if you can move the needle, if the needle moves freely, it may have come loose from the spindle.
Sometimes this happens, all you need to do is, push the needle (carefully)back onto the tiny spindle.
Good luck

The gauge is not attached to the face of the machine, I believe on the E61 it is.

I love the original faceplate, I realy like to keep it, or replace it with the same gauge.

The needle is actualy stuck on 0,1 bar. I will try to open it. Thanks for Eriks!

I meant visually the gauge style is similar, quite often the outer shrouds are removable, and you could re-use the shroud from your Lambro.

I have had some success repairing bourdon tube gauges by opening them up and making sure all the small gears are correctly aligned. They are very small, and could have simply been mis-aligned during transport.

Did you have any luck with this? I have a similar gauge and it reads 0.2 bar at rest, but then seems to work correctly, just reading what I assume is 0.2 bar high throughout the range. Can I just pull off the needle and reseat it, or even just carefully twist it? Ie is it a simple 'press fit'?

As the machine has no vacuum breaker, I assume its been twisted on the spindle as some negative pressure has occurred as the machine has cooled down.

I've managed to pry a couple of needles off and re-seat them at zero.Of course, i wouldn't vouch for its accuracy after this, but as they're only a guide, and renowned for not being very accurate anyway.I did re-test one by checking against a steam arm mounted gauge, and it was reading about .05-.1 off.
You have to very careful though, especially with old gauges, and if a replacement wasn't available, i'd be a bit hesitant to try it.In a worst case scenario, they are re-buildable.
