JD 710 Hydraulic isues

Sharosa · Feb 12, 2013

Having issues with the hydraulics on my 65/66 JD 710. I have a bucket on the front travels up slowly when revved up. 3 point hitch occasionally will raise. Hydraulic oil is up, no noises coming from hydraulic pump. Any help would be greatly appreciated.

Have you checked/cleaned/replaced these strainers??

The strainers are on the return side. The oil is basically drawn to the pump from the small plastic resevoir attached to the bottom of the top lift cover. There is plastic "trumpet" in the tank and a line to the pump. Check to see if the oil is foamy as there is a plastic gasket where the line goes on the pump and a place where air can be drawn in. If it has power steering the priority valve on top of the pump sends the first 3 gallons there. The total gallons per minute output is only 6 or 7 gallons at full engine speed[2400rpm] so there isn't that much left for loader or other functions. I'd check that plastic gasket at the pump first. If it is cold[less than -10 degreesC/15degreesF] make sure the oil is not a too high a viscosity. Use a straight hydraulic oil of no higher than #32 grade viscosity. Do pressure test on the system when warmed up and see if you have at least 2200 psi. Hope this helps....Ron
