I think the valves underneath are using the flow for the jacks to divert to blade or something along them lines . I remember seeing the electric cables going to them

do it as well as you can,but learn to do it better
05/05 is stab's up/down so will be H&J circuits, feeding a set of solenoid valves down stairs to control the circuits required ... virtually same as the 'Drema's

Yes flow and direction are controlled via H and J but the V solenoids are not directional control... they are basically shut of valves. H and J control direction... V solenoids block flow to whichever function you want to lock out

Its the "nose" you need to go by. Would need to take yours out and have a look to be fair

Turning joint from below . There is a pair of solenoids tucked in there as well but to difficult to see what they are actually doing

Komatsu tech guy says it's the 39 one. It's on its way to me. However, I've been looking further at the hydraulic drawings of which there are 3.
The one I posted yesterday is on page 3 and clearly shows V15 (or so I thought)
I was trying to understand the turning joint pipework and was looking at drawing 1 and seen another V15 valve. It says 2 stage back pressure.
the Komatsu guy says this is the one we are replacing and it doesn't seem to have anything to do with the jacks .

I'm not sure yet but as you can see it's like Medusa's Barnet in that turning joint

need to find where A1 valve block is with V15, V16 & V17 solenoids in it ... still 99% sure it'll be downstairs

Just got email back from tech guy . The machine has 2 V15 connectors .need to find where A1 valve block is with V15, V16 & V17 solenoids in it ... still 99% sure it'll be downstairs
one above and one below . I’m going to change the one I have issues with then see what’s what from there. He reckons that it won’t effect my jacks though

I noticed that celotex came in for some stick in the grenfell review. I don’t know was it TP10 extruded foam boards that was used but in this instance I’m happy with 70mm concrete on top of it . I do have 40mm of it specced behind plasterboard though that I will look into for sure before I commit.watch that Kingspan doesn't catch fire
I do have emergency services on site though . You must of missed grandsons fire engine by the caravan !

And still trying to work out if that's a toy dumper or a real one- the scales throw it out of whack!

It’s what I do!
How much was the plot? And how big is it all?
