MB trac 1000 three point drops and goes up again - JohannesG - 06.03.2019

Hi

Our MB trac 1000 -85 tends to slowly drop heavier implements a couple of centimeters and than lift it up again, and repeats the process. If I pull up the flow restrictor it stays i one place. So I'm quite sure that the problem lays in the valve. Are there any seals that can be replaced? Or what can I do to fix the problem?

Greetings from Sweden

Hi Johannes,

This thread has already discussed your problem:

Your hydraulic valve is leaking inside.

Here you can find information about a company in Germany that offers maintenance:

Thanks! I tend to find it hard searching with the correct words in German.

An other question about the valve for the three point hitch:
On our 900 turbo -90 There is a play when slowly lifting the arms. If I pull the lever very slow the arms go up in steps, not smooth as on our 1000. When lowering everything is fine and almost millimeter accurate. From what I can see all parts from the eccentric disc to the valve are intact and moving freely. Is it possible that I've missed something or is it something that is worn or can be adjusted in the valve?

Thanks. I actually have that exact document in Swedish. But from my understanding they refer to Bosch when the "Neutralbereich" is to big. Or have I overlooked something that can cause the same symptom?
