Hi all
I have a Hitachi ex-120-1, this is my 1st excavator and I use it for works around my own property.
I don’t have an operators manual, so real greenhorn, so bear with me if questions seem silly.!!.
I am building a house at the movement so with little spare time I try and squeeze in some repairs to the 120. I have only spent a few hundred hours in this machine, and the problem with the track motors, is there since I bought it, and got no worse.
When I lift up and spin the tracks mid-air, one side is much faster than the other, and during tracking, there is a turn to one side,
I am expecting work case the slower motor is dying., but id’ like to rule out that I’m not running a hare on one motor, a tortoise on the other first.
The hare and tortoise modes, fast/slow,are these only for track speed, and what does this switch activate on/off, is it related to solenoids on the track motor pilot controls??
The switch does turn the green indicator on the dash panel, on/off, but there is no change in speed, to either motor, so what should this switch be activating, relay/solenod etc..
