    1995 John Deere 490E Angle Sensor Question

    I replaced the PVC and the machine ran better but not perfect. The PVC is showing code 22 which is the hydraulic pump control not performing correctly. Manual said it could be the angle sensor, pump displacement solenoid valve, PVC or wiring. Angle sensor and solenoid valves checked ok. PVC...

    1995 John Deere 490E Angle Sensor Question

    Thanks. I have changed the angle sensor earlier on and set it at 4.4 volts. I am assuming then this was the 5 volt sensor.

    1995 John Deere 490E Angle Sensor Question

    I unplugged the angle sensor, pressure sensor and dp sensor. Turned key on and no light on PVC. Checked fuses again, they were good. I had found an old PVC in cab when I had bought machine so I cleaned the connection and installed it. Turned key on and light came on. It showed the...

    1995 John Deere 490E Angle Sensor Question

    Thanks again! If I can’t get PVC to come back on then will try new one I guess. I don’t think we unplugged or plugged the EC Motor in with key on but with all the checking and probing it could have happened. I didn’t see that about the EC Motor but I saw it about the EC I’m thinking.

    1995 John Deere 490E Angle Sensor Question

    Thanks! I will double check the ground and power to PVC by backprobing. I was able to ground to cab and check the fuses again, all were at 24v, either on the left side of fuse or the right. When I checked continuity on EC Motor and the EC Motor sensor, one of the wires didn’t pass the test...

    1995 John Deere 490E Angle Sensor Question

    So I checked the two fusible links that are in the battery compartment by removing battery cables and then checking the links visibly and by continuity. I reinstalled battery cables and went to look at codes again and the PVC is not responding and the EC is flashing 4 then 5. The same place I...

    1995 John Deere 490E Angle Sensor Question

    Update...replaced pressure sensor with no change. Error code (28) still shows pressure sensor not pugged in or bad. Checked harness and had continuity and 5 volts. So...I operated the machine for about an hour. I dug up two large oak stumps and machine did fair. The travel in turtle may or...

    1995 John Deere 490E Angle Sensor Question

    Thanks for the reading material! The code I was getting on the PVC was 28 which relates to the pressure sensor (P). The wiring checked ok. Since I don’t know how to check the P sensor I ordered a new one. Has not come in yet. When I ran the machine last time the pvc shut off after running...

    1995 John Deere 490E Angle Sensor Question

    Also I have read in a post about angle sensor being adjusted at max swash angle. Is that with boom down, arm extended and bucket curled in with bottom flat on ground?

    1995 John Deere 490E Angle Sensor Question

    I don't see anything in manual about a 5 volt reference circuit. I don't understand what that is.

    1995 John Deere 490E Angle Sensor Question

    Update...I have changed the fuses on the left side of panel. All fuses have power but I am not able to ground in cab and get 24 v at fuses. Usually about 18 v. If I run a wire from battery ground and check fuses then I have 24v. I removed the PVC and put a new resistor in. Reinstalled the...

    1995 John Deere 490E Angle Sensor Question

    I will double check but I am pretty sure there is a 3 amp fuse in F7. I will get a 1 amp. All the fuses were showing voltage. So remove harness and check for power to PVC. I am assuming manual has diagram showing location of power on the harness connector. The ground is the mounting...

    1995 John Deere 490E Angle Sensor Question

    Thanks for answering. I was looking at the EC light blinking 5 then 4. The PVC Controller light is not blinking. I checked fuses again and they were good. I tried doing diagnostic test by putting wire in data port but no light on the PVC. One of the displacement solenoids looks to be new...

    1995 John Deere 490E Angle Sensor Question

    I am brand new to this machine and have read most of the posts about the 490e. I purchased the 1504 and 1505 manuals. The problem is the hydraulics will stall the machine when raising boom, extending stick and opening the bucket. I started with the angle sensor. The sensor on the machine...

    Kubota kx080-3 vs. Kx080-4 reliability

    I have a 2008 kx080-3 with 4400 hrs. No trouble yet. I was curious as to which hydraulic oil you were using. I am in South Mississippi so we go from 100+ summer to 30 in the winter. I have been using Shell Tellus VX68 which from my understanding has a wide temp range. Thanks and glad your...

    Kubota KX080-3 Hydraulic Hose Repair | Have To Raise Cab?

    I finally got the two hoses out. Somebody has already changed these or other hoses in this area because all the clamps were gone or at least the top part. I hooked a ratchet strap to the hose again and just kept pulling and tightening until it started coming then pulled out by hand only...

    Kubota KX080-3 Hydraulic Hose Repair | Have To Raise Cab?

    The hose will move some, like 6”, but stops. I think it's hung up on the other hoses. That’s a nice machine. I ran an older 308 a few months ago and it was quiet. It didn’t have the hydraulic whine my Kubota has. I just bought the hydraulic return filter, fuel filter, oil filter, air filter...

    Thank you. So do you like the Cat 308 better than the Kubota?
