580 Super N Hydraulic power

mardi 5 août 2014

I'm working on a 2012 Super N tier 2, the outriggers are too weak to lift the backhoe more than a few inches and some times they just stop moving all together.Neither the boom nor the loader lift the machine unless the power lift is selected. There are a few fault codes 1045, 3173, 1019,1021,1018 listed new to old the last fault occurred 5 hours ago, all i have is the SM maintenance book so I have no clue what they mean. I flushed the Hyd fluid, changed the filter, and the breather on the reservoir, bled all the air out but the problem is still there. The pump whines a bit but dose not sound like it's bad. Currently looking for a gauge to check pressures but any ideas would be appreciated so I can get it back in the field.
