I just did some repair work on an John Deere 410D where I replaced the swing cylinder and main front loader hydraulic hose. I lose a ton of fluid and need to replace it, but im completely lost on how to do this? I have 2 fill tubes on my machine that I can see one is a hydraulic fill tube up top and one is a reverser oil reservoir. I added oil to the hydraulic reservoir up top and it seemed to be filling the bottom reverser oil reservoir so i'm guessing that's not right? When I ran the machine the hydraulics were extremely slow and choppy so i'm guessing thats def not right and I shut off the machine right away. I have a service manual for it, but it doesn't really tell you how to refill it. Could anyone give me a little guidance on where the fill plug is even located at or if i'm filling the right thing?
Hydraulic oil is to be added here. It should not come out the other one.
Thank you for getting back to me on this. I'm going to fill it today and hope everything is in good shape ready to go.
