NX6010 suction side hydro leak

[JimR]

Any ideas about the screen that would induce foaming? Restrictions, or something else?

I wonder if it is possible to run a return line down into the oil itself. That would cure this problem if bbn it is airating from the return above. As I recall you did install a clear hose on the suction side.

May be possible, but I don't think it would help in this case. From the video I took, the oil is already coming down aerated. Putting a return line down into the oil would only put the aerated oil further down in the sump.

On the suction line can you still see air going thru to the pump?

 

[justman777]

Jim---Yes, I still see small bubbles going through the suction line to the pump. I'm also still getting noise in the HST and stuttering in reverse.

Seems to me there is a screen in the fitting at the three-point-housing/ rear-SCV-valve-stack on the hose that comes in from the power beyond port on the loader valve. You may want to pull that fitting out and inspect the screen for anything that could induce foaming.

Fluid wise, I'm using NAPA's J20C hydro-trans fluid. Kioti specs their hydro fluid between J20C and J20D and I cannot find a source for J20D (the cold weather spec hydro-trans fluid).

I took out the return line bolt that goes to the top of the three point housing. That's an interesting bolt! Has a screen in the tip. I cleaned out the screen, but didn't see where it was clogged or inhibited in any way. I got everything back together, and it didn't seem to make any difference. Still got aeration. :thumbdown:

I have looked at my clear suction hose several times since you first posted this up. I have yet to see any air bubbles in my suction line. I was hoping that your post this time was that the problem has been solved.

I was reaching. Do you have a third function?

 

[justman777]

Yes. Kioti branded third function. I installed it about 3 months after I bought the tractor. I can't recall for sure, but I think I was having trouble from the beginning. Have to go back and look at my emails to the dealer.

Ok...looked through emails and discerned I was having issues prior to the 3rd function install.

How long after start-up do you first notice a drop in performance?

If immediately, then begin confirming proper flow through the power beyond port by disconnecting it, and feeding the end that would go into the rear valve stack/three point into a bucket and measure flow and look for foaming on start-up.
