    Terex T200/T25 or Matbro TR200/250 Transmission oil leak

    Hi, Thanks for the replies so far. The machine is a Terex 250. Initially I thought that the 200 has the same transmission but I was not correct in this assumption. I had a further look at the transmission. From what I can see, both the front and back sides of the transmission look the same...

    Terex T200/T25 or Matbro TR200/250 Transmission oil leak

    Hi, I was only looking at the back seal which seems to have no nut in the centre. If I remove the nut on the centre of the shaft on the handbrake side, will the complete shaft then slide out the back of the transmission? Regards Tom

    Hi, I have a Terex T200 with an oil leaking from the transmission output shafts oil seals. I can remove the drive shafts but it is not clear how to remove the flanges from the output shafts of the transmission. They appear to be press fitted over the shaft but I dont have a manual to check if...

    Hanomag D600 D Powershift transmission pressure

    OK, Some further testing done. Measured the pressure at the outlet of the pump and measured 150ps. Measured again at the test port and got 50psi. Removed the oil filter and the pressure out of the pump dropped to around 60psi, raising a bit when engine revved but nothing much. From this...

    Hitachi 120-3 Hydraulic / Electronic problems

    I forgot to update this thread with the status of the Hitachi Excavator. Good news is it is working perfectly now. After fixing the alternator it was found that there were two remaining faults. There was a bad wire on the DP sensor which caused the pump to go into full squash all the time. The...

    Hitachi 120-3 Hydraulic / Electronic problems

    Thanks for all the updates so far. Update on the Hydraulic problems: The alternator replaced and the voltage is now back to normal 29 volts when charging. I then re-fitted the angle sensor. When fitting and setting up the angle sensor I first had it at 4.3 volts output on the pump while the...

    Hitachi 120-3 Hydraulic / Electronic problems

    Thanks for the word of warning, I will keep that in mind. I think it is safer to replace the alternator before doing anything.

    Hitachi 120-3 Hydraulic / Electronic problems

    While we are waiting for a replacement alternator we will try running the machine with the alternator disconnected. Hopefully it will behave itself a little better then. Going to be the weekend before we can look at it.

    Hitachi 120-3 Hydraulic / Electronic problems

    The filters are OK, There is not too much history except that the machine was purchased with the problem. Initial debug found that the wiring on the pump solenoids had been reversed so the pump was in full squash all the time. To clarify what I said previously, I removed the angle sensor from...

    Hitachi 120-3 Hydraulic / Electronic problems

    Hi, some further debug has shown that there is a problem with the alternator as the voltage at the battery when charging is around 36V. Max 28V is what I would be expecting. The heartbeat LEDs on the ECUs look to be OK. The other thing I found is if I rotate the angle sensor on the pump while...
