If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

a strange choice on jake's part, as a pressure check outlet
New line'd be about 20 quid I'd guessIf it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

@v8druid
The vendor would take the set back. But the most important is, to buy the next time the right.
I compared the both ads again:
The right one for Stauff?:
http://www.ebay.co.uk/itm/Hydraulic-...p2047675.l2557
The wrong which I have:
http://www.ebay.co.uk/itm/JCB-hydrau...3D172433509562
But supposedly the same content!!:
KIT CONTENTS
• 2 x 63mm glycerine filled pressure gauges user selectable up to 700 bar.
• 2 x MinimessTM 1620 test points - 1/4” BSP & M10x1 threaded. 1 x G1/4” BSP to 1620 gauge adaptor.
• 1 x 630 bar rated MinimessTM pressure test hose - 1.5 meters long.
• Additional 3/8” & 1/2” BSP male threaded adaptors & seals.
Thereīs something wrong...
My testpoint is: Stauff Test 20 (M16x2)

To get more safety I looked direct at the site of the vendor. But itīs not easy.
This should be mine kit:
http://www.hydrotechnik.co.uk/jcb-st...re-testing-kit
The content is described as:
2 gauges
2 HSP test points 1/4 & 1/8" BSP,
Adaptors for 1/2" & 3/4" BSP
3 male / female adaptors with test points fitted: 1/4", 1/2" & 3/4"
Direct gauge connector
2m length of microbore hose for connecting test point to gauge
Cleaning cloth and dowty washers.
In the PDF-file the Content is described as:
2 x 63mm glycerine filled pressure gauges user selectable up to 700 bar.
3 x Male/Swivel Female inline test point plug adaptors. 1/4", 3/8" & 1/2" BSP.
1 x JCB style test point plug - 1/4" BSP. 1 x G1/4" BSP to JCB style test point plug female.
1 x 400 bar rated pressure test hose - 1.5 meters Long.
Additional 3/8" & 1/2" BSP male threaded adaptors & seals.
It seems not identical. For a hydro-beginner this is lethal.

Reading wove's experiencing with great respect. Might have similar excercises coming with my -15b xtv. Hydraulics, as simple as it is, still a bit mysterious to me, especially the world of various control valves. The problem is in two things: what are the various symbols on the diagram and how do those look like in real life.
Could you post some pics. on the measurement you do on the valve block?
Does one simply connect the gauge ( engine not running?) and then what? Does the oil come out when connecting? How do I know the right pressure? I assume I should operate the circuit to get the pressure.
I feel more home with the electrical circuits...

But one seems necessary: I donīt know much of hydraulics. But I know, that working on it is not harmless. High pressure injections into your body cause a heavy thread to your health! You must know what you do!
[QUOTE][How do I know the right pressure? I assume I should operate the circuit to get the pressure./QUOTE]
This answers only the tech doc of your digger.

I started a thread about understanding the EC15:

You can use it for questions. Some things can be solved by a question, but some themes need own hard effort.

Thanks wove,Can't quote all your texts and write without quotes.
I have the service manual downloaded, all 600+ pages in iBooks. Poor user interface but the information is there. Haven't had time to study the secrets too deeply, but will do in case have an issue.
The check valve being like a diode was great news as I know exactly how a diode works. Likewise the Rexroth SX12 will fill an information gap size of Grand Canyon. Thanks!
Understand that hydraulics involve high pressures and that calls for at least eye protection when opening circuits.
I'm holding masters degree on electrotechnics and additionally have been doing quite a lot mechanical overhaul for 4x4 pickups. Have a lot of tools and the only limit is time that seems get consumed to less important things than excavating

Utmost respect is required for high pressure hydraulic systems ............ the dangers can not be over-emphasisedIf it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

This a fact gentlemen .. (as many of you know) Medically, problems can even be worse than described .. small amounts of injected oil in the blood stream can be fatal, because it causes blood poisoning, which then causes vital organs to shut down if it is a significant enough dose .. so extreme caution is the rule.
I also try to avoid holding test equipment in case of bursts, when doing pressure tests.
Another huge no no .. is using heat on any metal pipe work, whilst its still connected to a sealed circuit. In all cases it must be drained and opened beforehand. Might sound obvious to some but ..hydraulic oil is highly flammable when hot, a depressurised circuit will gain pressure when heated from an external sourcePlease don't PM me for plant advice.. thanks ..
