Okay, I started her up day before last, and dug a bit of clay out of the bank, and it was right gutless. I changed the fuel filters and tried again, same results with no change, gutless. So my last lil test run after the new fuel filters installed I walked it a bit (right track spins when in the air but not under the weight of the machine) and when I moved the boom up or down or curled the bucket the machine (motor) bogged down slightly.
So I am thinking if that"s the case the pump must be starving for hydraulic oil right? So I am assuming there must be a mesh screen inside the hydraulic oil tank like my dozer and loader do, and I am assuming there must be some main hydraulic filters but I can"t seem to locate the hydraulic filters. At the bottom of the tank there is a huge hose that feeds into the pump, and from there several lines that feed several valve banks.
Since there is no apparent spin on filter, the filter must be inside the tank no? If it is (I am going to dunk my arm into the tank to find out after supper) and I manage to change it, whats to keep the contamination out of the pump? This is too simple to be complicated! lol
