Ive cleaned hyd filter and had the pump tested at a hyd repair shop . Pump is ok with just minor normal wear. I checked the suction line no problem there. Took relief valve apart and shimmed behind the spring but no improvement.
Ive turned the directional valve every way possible and nothing...
In a bind here. I've got my father- in -laws tractor. Sudden loss of hydraulics. What are the possible probs. Is there a shear pin in the pump or a relief valve that could be causing the problem? Is this a dealer only repair? Is there something I could check first? Any help is appreciated...
