Hydraulics on 560 running

If one of the remote valves (where you set it for either double or single acting cylinders) is in a bad position it will cause the “running” condition you describe. If you have changed any of these lately because of changing types of cylinders used on the remotes, this might be the cause. Try turning them to a slightly different position to see if the “running” stops. If so, you have found the cause, now you just need to play with the setting until the cylinder works correctly and the “running” is gone.

This one is not as likely but can happen. If the “running” stops with the fast hitch somewhere between all the way up and all the way down, then the stops for the touch control lever for up and down are adjusted to a position that is impossible for the hitch to get to. This adjustment is regulated by the two set-screws “stops” for the lever that actuates the fast hitch. In this case you need to screw them in further so that the lever stops while the cylinder is still in the range where the position you have selected is obtainable.

Hope this helps.

Your hydraulic system is staying in a hi-pressure condition--the only 'rest' it gets is when it has a chance to move oil through relatively large openings such as actuating the fast hitch cylinder.

The hydraulic pump has to move oil at all times, or it will damage itself and other stuff. When hydraulic oil (pressure) IS NOT diverted to actuating the fast hitch cylinder or remote cylinders, the pump's output MUST be diverted back to back to the sump. This is accomplished by the regulator and orifice plug/screen. IF these aren't doing their jobs (unloading the system by dumping hydraulic pump output oil to the sump), THEN hydraulic oil has to scream through the relief valve. This situation will most definitely bog down the 560.

Most likely the orifice plug/screen is blocked by crud. Consult your manual for their location. They're very easy to remove and clean. There are some other things that may cause the hi-pressure condition you describe, but the orifice plug/screen is the first place to look IMO.

Post again with your findings, or if you need more assistance.
