Problems with hydraulic lift up and power steering oil tank overflows oil

Ruud3a · Mar 25, 2023

Hello guys!
I previousley cleaned my TL2300 Iseki hydraulic filter and it's housing and now I can't lift hydraulic. Where is my problem and where I need to look?
Second quite similar problem is steering oil reservoir overflows when I start the engine. What cause this problems?
I would like to think about air in the system. Where is the places to push it out from the systems in these tractors?
I had no luck to get service manual, but I make my best to improvise and thinking as logical as I could.

Hi Ruud3a,

I'll let someone else answer the hydraulic issue, but I have suggestions for the power steering oil issue. I had a similar issue on a Ford. It started for no reason or cause that I could see. The oil was overflowing because it was foaming and the air massively increased the volume. No amount of bleeding would resolve the issue. Bleeding in this case, which I have commonly seen in other vehicles, was to fully turn the steering wheel to the left and right a few times. The air was being sucked in, and logic suggested this was on the suction side of the power steering pump. Suggestions on this site matched that. After checking all the connections from the intake to the reservoir, I went with the advice that the shaft seal was likely leaking air into the pump and that was correct. I put a seals kit thru the pump and it worked. I think this will be similar to your situation.

Hi FordnMassey!
Thank you kindly, I'll try this way as you describe me. I hope this will solve my problem with steering oil overflowing.

If you are getting air in the steering look for a small leak in the hoses. Did you fill the filter housing with oil? Crack the pressure line at the pump. This will keep from any pressure building up.
