    JD490 bucket cylinder not retracting after servicing - what did I do? Need Help.

    Hi Mike, I have not disconnected the pilot lines yet, should I try at the valve body? I don't have a pressure gauge - can get one here tomorrow, so I don't know the pressure to the cylinder, when I opened the cylinder line and ran it into a bucket it was like a garden hose not on full blast if...

    JD490 bucket cylinder not retracting after servicing - what did I do? Need Help.

    Joe - its a 490D, Uffex, I don't believe it is a broken / separated piston, as I also don't have down pressure on the the boom - ie -it won't lift lift the machine off the ground, seems to be more of a gravity down, but it will lift up. The book says its an open center system, but in trying to...

    JD490 bucket cylinder not retracting after servicing - what did I do? Need Help.

    Thanks, I used zip lock back and gorilla tape over all the ports, so no rags in there for sure. No air in the pump as I checked the purge port there, will try a line.

    JD490 bucket cylinder not retracting after servicing - what did I do? Need Help.

There is an access cover under the main boom pins I removed and checked to be sure, and yes its full of oil. From under the machine when looking up at the center manifold there are two...

    Need advice with a leak on JD490D excavator

    Thanks Willie, I know the port you are talking about, but that is gear oil, and it is hydraulic oil that is leaking. What do you mean by the "Center rotating joint"?

    One more JD 490 question

    Can anybody tell me if a 1987 JD490D would have come with a valve to swap from JD to Cat controls? If so where would I look for it? This machine is a Fabtek processor conversion and has a lot of additional valves, and lines to it. If there is no switching valve I am presuming I can just swap...

    JD 490D question on yellow button function

    Got my new to me 490D with a Fabtek harvester conversion today. I have an electrical gremlin in the harvester, but my question is what does the 1" yellow momentary push button behind the heater controls on the right side do? The label is worn off. Thanks. I think I attached a photo of the...
