    Finally fixed the dreaded MM55SR excavator for good.

    Yeah absolutely I knew a little bit about hydraulics going into it, but now understand them alot better. Its not just valve bank and controls there are also all these special hydrulic components in the mix too.

Swapped in the main pump, valve block, pipework, hoses and controls, then reworked everything to suit the machine. When the whole setup arrived from an excavator dismantler in one big crate...

    Retro fitted complete Hitachi ZX50U-2 hydrulic system into another excavator have pressure issues.

    I’ve transplanted the entire hydraulic system from a ZX50U-2 into a different machine. I’ve followed the drawings as best as I can. When I fire it up, I get very little pressure—cylinders barely move in the pin clearance and it can’t lift any weight. I want to confirm exactly what lines or pilot...
