Renville County, MN | If you are running your return from your orbit motor into SCV and case drain hooked up to case drain coupler as you have shown in pictures you are hooking it correct. Best would be to hook motor return to a coupler that is hooked into port marked return right above case drain coupler. It is possible that you have a internal leak in the pump that is dumping off oil to sump and draining the reservoir. I think the code you are talking about that is coming up is for low reservoir oil which is not the one you see in the sight glass on rear of tractor. There is a internal reservoir. We have had this happen a couple of times once on a 8400 and then on a 8310. There was internal leakage in the main hydraulic pump that would leak excessive amounts of oil when pump was set into high pressure. This would cause the reservoir to drain down and set code as it was dumping more oil back to sump than it was returning. Just my two cents of what is going wrong. If you only use the hydraulics for lifting wheels etc you might never know it was happening. | |
