Hi Rene, Usually when you loose half your functions it is an indication of one half of your pump failing or one side is not getting signal pressure to stroke the pump to full flow.A quick initial first check would be to check the in tank hydraulic filter for fine metal/debris indicating a pump or component failure. Let me know

I checked filter no metal
Mechanic: Dan, Technician replied 2 years ago

Ok, Check the signal pressure to the pumps and verify both pumps are getting signal pressure to the pump control valves when the functions are operated.... Check your pilot pressure. Its usually in the range of around 550-600 PSI
