While I'm still working on other issues on my 763 I wanted to post a question about removing water from the hydraulic system. The guy I bought the machine from was not 100% honest as over time from talking to some of his helpers I was told conflicting information by all of them so who knows what to believe. Regardless its all my headache now.
When I first bought the 763 it would start and run but had hydraulic problems. The hoses on the lift cylinder were busted and spitting hydraulic fluid. I remember watching it come out and as milky apparently it had water in it but was a lot more oil than water. The guy said he had a worker who started working on it and stopped and he didn't need the equipment any longer as he as getting out of the construction business. Later I came into contact with others who worked for him. One said he owed someone money for storage that was messing with his equipment. Another said the machine had hydraulic issues but he wasn't sure what they were. All are drunk so who knows at this point.
As I track the hydraulic issues to get them sorted out, I have dropped all the hydraulic oil and refilled it with new oil 3 times including new filter in the engine compartment. While The oil is mainly still all oil when I run it, if I look in the hydraulic oil tank it is still a little cloudy and has tiny bubbles.
So at this point I don't know how it got in there to start with. It could have been the guy he owed money to that sabotoged it by putting water in his tank but find it hard to buy since none of the other fluids had it in it and not that I would do that but if it was me that was going to do that I would certainly pick sand instead. It may be that he left the cap off and water got in that way. Who knows but at this point it doesn't matter.
Is there an additive I can but in that will dry that water out? What is the best method to use? Also what is the proper way to pump all of the oil out or the machine? I do not think you can run it dry but if you add oil as a flush then you may never get all the water out?
