I purchased a really rough TH83 telehandler in early November after wanting one for a while. I don’t have much heavy equipment experience at all so thought this would be a good project to start with. It ran fine but most switches didn’t function. Only steer select worked and the previous owners had really done some interesting rig jobs on the cab wiring so I completely pulled everything out over the course of a month and put original parts back in and completely rebuilt the wiring harness (cab). All my switches work again except my mast tilt.
I’m certain it’s not the relay in the cab, and the joystick buttons are good.
I haven’t had it running but for 10 minutes since I have owned it because I wanted to make sure things were right. Now it is low on hydraulic oil, would this cause the tilt function to maybe not work since that cylinder is one of the furthest away?
I plan on changing all the fluids but I did not know if I should wait until I have confirmed I don’t have to replace anything that would require me to just change the fluids all over again so my question is...
If this previous owner put hydraulic fluid in the rig and it actually calls for motor oil in the hydraulic system as per owners manual, does it hurt anything if I put motor oil in it and mix? From what I got out of talking to the last owner, he was using elevator hydraulic fluid that he had a 55 gallon barrel of. I have no idea if that’s fine or not but I am eventually going to change it just so I am certain I know what is in it.
The questions I have from all my rambling.
1. Would being low on hydraulic fluid cause my mast tilt not to work, but my boom lift and lower was fine (I haven’t tested the boom in/out yet)?
2. Is it ok for a brief period to potentially mix motor oil and hydraulic fluid?
