    Volvo EC27D Hydraulics

    Hi All,

    Has any one got or had seat time in a volvo ec27d?

    Mine has 200hrs showing now, just changed hydraulic filters but the machine is getting worse to operate, not smooth hydraulics, as if oil is pulsing/lumpy, when dipper ram reaches end of stroke it just bangs to a stop.

    Basically just not nice to operate & seems to get worse all the time...

    Anyone got any thoughts?

    Machine was bought brand new, had no work done on it , hoses replaced etc.

    Anything else that might be helpful?

    The dipper ram also makes a loud bang when it is fully extended out, rest of rams just stop smoothly when hitting there stops?

    A lot of rams are fitted with cushioning valves to stop this happening . Maybe it is faulty ?.
    Back in the old days rams weren't fitted with them , it was down to good operating skills to not bottom out the ram .

    Yes possibly it is faulty as it is the only ram that does it, Cheers
