I've got a 2021 KX-040 coming in 3 weeks so I'll need to become familiar with the 5 ton machine ... I'm sure you have ... but did you check the hydraulic fluid level in the tank? Are you experiencing any performance issues with any other min-ex movements? When you say "hard time turning from both right and left" do you mean with the tracks or with the turn-table? Sorry, I'm not a pro with the mini-ex at all but I'd love to come along for the ride as you figure this out.
Thank you I will check out the service manual again to see if I missed anything.. not familiar with it but I will check it again.Might I suggest you get the WSM (aka Service manual) it will give you all of the troubleshooting and pressures needed.
I've never gotten a manual for this place so use at your own risk.

That I don't know but I will check without using the high speed. it's on when the thumb is operating.
I'm not sure the previous owner told me that he changed all the hydrolic filters inside and the one outside the tank and clean the tank as well. He said a very experience mechanic did it.. Buy now I'm doubtful I'll try to see what type of oil it has..
the machine will move forward and backwards no problem.. but if you put pressure on one track either left or right it will not turn.. so the entire machine will not turn either left or right. what I do is hit it back and forth so it will turn a little and that is how I get it to turn a little by little.. so I cant for example make a left or right turn at a dead stop... making the turn or operate on only one track it will not go forward or backwards..
Thanks let me look for that rabbit.. now there is a button on the machine in the middle of the display that operates the thumb.. the thumb does not operate when that is off... Im not sure if that is what your calling the rabbit.. but I will take a look at in the morning .. thank you I appreciate everyone's help.
Maybe a picture of the dash and controls will help.
No. Not that button. Look or feel for a button on the bottom side of the dozer blade control stick. There should be a button that turns on/off the track speed control. When the tracks are in high speed the rabbit on the dash should be lit up telling you that you are in "high gear". You'd need to be in "low gear" to turn sharply.
I bought an old KX41-2V excavator recently. It will not turn (I believe, trusting my memory) if stopped, and if I try to turn with only one track. It will turn when stationary if I put one track in forward and the other in reverse.
You should have Bi Speed, I am thinking on yours it is switched with a pedal on the floor.
I will have to check it out. I do plan on buying the manuals (workshop, operator's and parts) for this excavator from Kubota, but have not got around to it yet.
