7020 hydraulic filter light

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My 7020 hydraulic filter light comes on until the tractor warms up, and flashes on when I drop my 3 point or release a remote lever. For the last year it’s made a starving sound occasionally. It is full of 821xl oil, and I changed the belly filters and cleaned the screen on the pump when I bought the tractor a couple years ago. The gear pump is silver like it’s been replaced with a new one since the tractor was painted at the factory. I thought maybe the last owner was having problems and maybe threw a new pump on trying to fix it. Would the priority valve cause this? I’m going to change filters again but I think something else is going on.

	Could be normal in cold weather. The wonder is on right side filter, which reads resistance as oil is pushed through right filter. MACK
