    Hello rockcreek4630 Thank you for your help. I have 80W90 gear oil in the differential, without an additive. Maybe I should try with a hydraulic oil? ( I found some informations about using hyd.-oil in zf axles in google...) So my plan for the two extra hyd. valves should be working. :P...

    Hello I have a new question about the 4450. I saw an aux hydraulic kit for the 50 series tractors, its also called power beyond. Will it be working to use a power beyond/ aux hydr. kit for 2 extra electric hydraulic valves? Another question, does anyone have some experience with the ZF...

    Hi Tech 7 Thank you for your help! Yes if I turn the switch to off I have about 12,5 Volts and when switch is in on position it has about 1,4 - 1,5 Volts - so I think the switch works correct? The confusion is, that I think it worked once when I dissasembled the valve and reassembled. (I am...

    Hello Today my 4450 is in the "ac- shop" to get the aircondition back to work :wink: But since the last silage work, the mfwd doesn't work correct. I am not able to turn the mfwd off. What I tried to fix it is: - Voltage check on the solenoid - ok - Solenoid check for correct work...

    John Deere 4450

    Hello I have another question about the JD 4450. How would I notice that the hydraulic accumulator is less charged? To check the accumulators, how much pressure should they have? I think there are two of them, one for the seat and one for the Powershift? The seat lowers pretty fast, when I...

    John Deere 4450

    Hello I have another two question about the serial number plate. The first one is, where is the serial number written in the frame? And on the serial number plate on the right side of the front end (near the wheel) is a "coef abs" value (0,64). What does this mean? Should it be the emission...

    John Deere 4450

    Hello Thanks everyone for the nice help. We worked again on the 4450 and we opened the steering motor again and saw that the feedback piston pin was out of position. We assembled all back to the tractor and it worked as it should. :D Now there are only a few small things and the new...

    John Deere 4450

    Hello Thanks alot for your answers. So you mean, that I have to check the feedback piston? This will mean I have to remove the fuel tank and the whole steering motor, if I understood right from the Tech manual. I think this wont be a problem, it only means a few work :wink: But I have...

    John Deere 4450

    Hello I want to grab out this older topic, because the problem with the steering still exists. I like to know, if someone has an idea what I can do or try on the tractor? (the reason for that long "standing still time" is, that it is my hobby and I was a long time away...) I tried to...
