When shifting from forward to reverse or visa versa, trans is slow to go into gear and slips, if you let off the throttle then back on the trans goes into gear and is good. Pressure gauge shows low pressure until...

    Hitachi Ex120 Problem

    If you can turn the shaft in the pump easily were the angle sensor goes in, then that is your problem!! That shaft is hooked to the swash plates on the pump and should only move when they move. There is a small pin that holds the fork to the swash plate and that falls out causing your problem...

    Hitachi Ex120 Problem

    You need the manual to replace the sensor and set the voltage properly. You can put the machine into a limp mode in order to get it home. If you look on the bottom of bothe pumps there is a four bolt cap plate over the end of the swash cylinder pistons. If you remove that plate you will see that...

    490 E Hydraulic problem -Help Please

    The computer controls the ground wire from each of these solenoids and turns them on and off as oil flow is needed or not. It is not a regular pulse but on and off as the computer monitors pressure and engine rpm.

    Hitachi EX200-2 computer question

    That sounds like displacement solenoids to me. The coils tend to break down from the heat when they are older and then they stick, but when cooled off they are fine. I would change them both out!

    Pilot pressure pulses

    This is normal!! Don't worry about the pulse it is normal for these machines, it is just the pilot pressure relief valve doing its thing. No need to worry.

    Hitachi Ex120 Problem

    I have found that most hyd. problems on these machines are electrical problems! If the computer can not see what the pump is doing it will basically shut down and the pumps will slowly go to full swash and put out way too much oil and everything will speed up and loose power and the engine will...
