John Deere 3010 Propane... Lost hydraulics on my front loader and 3 point. Been reading a lot of forums and checked the filter and screen which were both clean. Read where you can de-stroke and then open back up to put it in stroke and it will sometimes clear any trash. My main question is- look at the attached picture of the bottom of the hydraulic pump. I also attached a picture of what they are referring to in the manual as a shut off screw which I assume means de-stroke but can’t determine if that screw on the bottom of the pump is actually the de-stroke screw or the pressure adjustment screw?? I can’t tell if the pic in the manual is on top or bottom of the pump. You can’t see much on top as it is propane and the tank and hydraulic radiator/ cooler are in the way. There is a hole in the cover plate right above the pump and feels like there is a nut/ bolt head on top right above the location where the screw is on the bottom. So, is that the de-stroke screw in the picture?
