John Deere 5105 hyd orbit motor problem Problems

I have a problem starting the auger hydraulic motor with a rattling sound, I need to start the motor at 1600rpm. I’m on the left scv, the filter is new, the gearbox mesh is clean. Good gasket and springs in the filter return box. This 5105 has 3 scv and 3ph load lever valve.

It will actually start the orbital motor, reporting that the make-up oil will run out. There is no light transmission or problems.

The problem occurs when the 3ph is up or down. The Scv performs well, as does the mid-mount hydraulic valve.

When the loader is driven up and down it also starts to vibrate after the third lift so it leaks make-up oil somewhere. The Beyond block power is in front of the left scv.

Does the feeding system have a flow control valve? If so, it is possible that it is set for an open system and is diverting oil all the time. In your system, you can use flow control on the main pressure line without bypassing it and start returning directly to the tractor. My guess is that your flow valve is bypassed right at the valve. What is not used for engine service is omitted. In other words, you are pumping your pump at full power all the time. Check what you have.
