    cat 308d sb

    They said pressure was down 1000psi , i assume all functions - was very weak on tracks and would struggle to lift machine up with the blade but seemed to operate quick and smoothly. Yes the old and new relief valve was adjusted on the valve block to try and increase pressure with the old and new...

    Backhoe with Aux Hydraulics Why THREE hoses?

    Hi, some attachments have an extra line such as a tarmac planer. When i used one on my backhoe i had to run the third smaller hose directly in to the hydraulic tank. I think it`s a relief line and it may be what yours is for

    pw75

    It may well have air in system. I can hear the machine build up pressure for a couple of seconds then releases and off we go. So was thinking maybe a valve or something out of adjustment. A pressure test might be the best bet to start off. Another thing which may give someone a clue is when...

    Jcb jz70

    Hi again robo, the zx 60 measures just under 6`7" wide and has the boom mounted on the front like a mini digger and has 12" tailswing over tracks so quite a versitile machine. Its nicer to drive - a/c, good stereo, hyd hitch and effortless controls, but as far as digging a straightforward hole...
