JD 710c backhoe/loader

[jfd43]

I was pulling a stump on the 710c when everything went sugglish,I pulled everything up and hauled butt. I'll be honest,i don't have a clue as to when it comes to hydraulics.I was told by a mechanic it has to be the front pump.I'm not to sure about that statement. I have pullsation in the line's going to the hydraulic filter. I have no power steering,brakes,no lift to the outriggers,front bucket,or backhoe.My shade tree mechanic skills lead me to believe the main pump went out.If there is anyone out there that has some good advice,i'm willing to listen.

First I would check the fluid levels, and check the screen and filters.

Install a hyd gage and check some pressures.

Re check all the QD's

I'm having the same problem. A friend of mine is letting me use this backhoe for free so I cleaned it up a bit and put seals in the outriggers. I was trying to move some dirt and the bucket quit lifting, the power steering, outriggers, rear bucket, everything quit. I changed the filter underneath the hoe last week and everything was fine, topped off the fluid and no leaks. But no it pulsates so bad and I can't get anything off the ground. I pulled a hose clamp off the cooler up front and tried to move the bucket to see if there was pressure, it blew the line off fine. The belt driven pump on the motor is turning fine, so I got under the hoe and looked for anything leaking or worn but everything looks fine. There is a block with hoses coming in and out of it right under the right side (sitting in it) in front of the rear tire on the frame, I took off this big bolt with a spring on the backside, oil came out and everything looked good. Any ideas? Im not an equipment mechanic but if pointed in the right direction I can figure most things out. Thank you, Kevin
