Hello everyone. I've got a John Deere 2640 with a 146 loader. The loader is plumbed correctly into the pressure control valve and returned into the filter housing. I have the original two spool loader valve that operates the loader. With the tractor turned off and loader raised, it doesn't take long for both the lift and bucket to leak off. My loader is plumbed with quick couplers at the pressure control valve and filter housing. With the tractor turned off and the loader lifted, I disconnected the return line and the loader will stay up all day like its supposed to. As soon as I plug the return line in it immediately begins to pop and creak as it slowly leaks off. The final test I did was putting the loader all the way down and disconnected the return line. I held my finger over the fitting to open the valve on the on the end of the return line. When I cranked the tractor the return line immediately pressurized and I could not depress the valve. Pretty sure that oil is constantly returning back to the filter housing. I read here that this should not be the case when the loader is not in use. I am thinking that there is something wrong with the loader valve itself. Am I on the right track? Can it be repaired? I've read in several places that the valve often cannot be repaired. I've also attached a photo of the bottom of my valve just to make sure that I have the pressure and return lines hooked up correctly. The one with the red circle is the return line.

In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
