I posted this before, but good people asked questions I didn't have answers for, so now I have some.1966 770 Oliver with dual hydraulic capabilities has no pressure or oil flow on either side lift or drop sides,I have been told the electrical wiring for the cylinder controls can be eliminated without affecting the the manual controls.( Question #1 is this correct ??) the tractor was on a farm feeding cattle for many years, so when I took over the farm I checked the hydraulic oil reservoir and it was 5 qts low on a 9.5 qt capacity. I have taken the foot platform cover off and with the tractor idling the shaft that runs the pump and PTO is spinning and it sounds like the hydraulic pump is spinning (question #2 could the problem be in the control valves??) (question #3 if I remove the control valve /reservoir what can I expect? the concern here is how the pump is connected to the control unit. if all discussions lead to a pump replacement how do I get it apart? I have a operators manual but no service manual, I would purchase one if I could find one. Any help or guidance would be appreciated

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
