You guys might remember a while back I posted about my son buying a 4010 with a rod through the side. Well we fixed the motor and it is running great but the hydraulic pump is really noisy and almost has a knock. The 3 point arms are real jumpy when going up but while they raising the pump quits making the noise. The steering and brakes work fine and they don't stop the pump when activating them. We had this tractor split so do we need to bleed the pump somehow? Sometimes when you shut the motor off it sounds like the hydraulic pump squeaks. Anybody have any ideas? I'm not to goog with these john deere hydraulic systems.
