Thanks for the video. Just bought a 490e and we are having about the same trouble. Throttle cannot be controlled from cab with buttons and hydraulics will stall engine on certain functions. I was told to look at angle sensor on hydraulic pump. If that doesn’t help I may do what you did with the plate.

I will watch all your videos

My hitachi 200ex-3 just went into limp mode today🤬. Going to do this then dive into the electrical and see what i come up with. Any tips on where to start would be great thanks. And great video also!!

Any updates on how this machine has been running recently? I have the same type of machine.

I noticed you made some videos on the old 86 trx350s, any chance you know where to get 0.75 over piston rings? I've looked everywhere, machine shops, online. Seems to be impossible to find, thanks

Hello any update on the machine is it still working ok? have the exact same machine fairly new to us it seems slower compared to our other machines going to try this tomorrow thanks for the video

I have a Hitachi ex 120-3 I believe it is the same machine different engine I was able to take those four bolts out and put a big pair of pliers on the plate and rotate it without pulling it out and I got the same result you did it didn’t bog down but it moved very slow but I found a fix for the hydraulics bogging down it may work for you if you’re interested get back in touch with me I was losing power at the pump relay so I hooked up a jumper wire to it from the wiper relay and it works the problem I’m having now is I’m not getting power to the control panel my machine only tracks in turtle what is the tracking slow problem came up long after I fixed the bogging down issue

Something is not getting power get a wiring diagram its a very simple system somewhere there's a solenoid valve closed or not opening all the way

Needs a pin & bush for the bucket too..
