I have a hydraulics question I hope you guys can help with. I bought an old Vermeer backhoe attachment (old meaning I can't even trace any info about it from Vermeer) that fits my CASE 1840 skidsteer. The factory specified hydraulic fluid for the CASE skidsteer is regular 10w40 motor oil and that's what I'm running. It has normal (NOT high flow) front auxilary hydraulics (15.3 GPM flow). My question is this: is 10w40 motor oil the kind of hydraulic fluid that this old Vermeer backhoe would have been designed for originally?? Or, more specifically, is the 10w40 correct for the valves in the controllers of the backhoe?? The backhoe works, but the controls are really "jerky". A tiny movement of the control levers results in slow smooth movement of the cylinders, but anything more than a tiny movement of the levers results in pretty violent jerky movements -- much faster movements than you would want for normal operation/use. So, is the 10w40 wrong? Are the control valves bad? Can the control valves be adjusted? (I'm a hydraulics newbie...like you couldn't tell that already...)
Thanks for any info you hydraulic veterans can provide!
