After a long time I changed my stretching hose, which goes from the central hydraulics down to the pressure storage tank, today. Said, done, in the place everything was now closed again, but probably not directly at the central hydraulics, because there it drips cheerfully out of the back, from the bracket down to the climate compressor or. The oil pan.
I could locate the leak spot very precisely and it probably affects one or two of the blink plugs...
Well, you think it's possible to switch at least where you can get it... but unfortunately I don't get it and I don't want to be a doctor forever either.
So I read the forum once and it does not pose a big challenge in itself... I was already in the assumption that the climate compressor and and dismantled would have to be.
I found this thread:
"How do you get the servo pump removed with the ABH motor"

....Is this leaky screw visible from above?
Last week, I was able to change a cross screw with a built-in central hydraulic pump.
To do this, I only took the left air guide to the air filter, the corresponding snorkel on the cooler, which is held with two plastic clips.
Removed the electric fan with two screws and placed aside and removed the front of the three hydraulic hoses.
Then I was able to access the leaky cross slot screw.
I used a long flat screwdriver, and hit the screw cross sideways with two targeted blows, so that a turning movement took place.
After that I turned out the cross screw, and made sure that the spring behind it with spring pin and piston did not fall down without a trace.
Now the new screw is wetted with hydraulic oil (O-Ring) and everything is assembled again.
To tighten the screw, I tightened it again to screw cross with several targeted impacts.
Two new O-rings used for the removed hydraulic hose (stretch hose ), and everything reassembled in reverse order.
Since I wanted to remove this pump completely first, I have new O-rings for the other two hoses from the friendly and the hollow screw, which should also be renewed, lying here with me.
If you need these, for a few cents, you can have these from me.
Just PN to me.
However, if you have to remove the pump completely due to inaccessibility, the pulley must also be removed from the pump (three all-in screws) and then the rib belt must be relaxed and taken down.
Then the pump at the front loose screws, are three screws, and at the back two screws remove, then you can remove the pump forward/upper.
Greetings Manfred.

...if you have the fan engine outside, there should be enough space to take the baby out. before the suction tube up. as already described, pull the five screws out of the jack from the front. Leave the bock on it, the installation with bock is otherwise extremely exhausting because you have to fry past the climate compressor.
Let me summarize for the expansion:
-Remove left airflow to the air filter(the corresponding snorkel on the cooler, which is held with two plastic clips)
-Electric fans which are fixed with two screws, remove and lay aside
-Screw off the belt disc from the pump ( three all-in-one screws )
-Relax the ribbed belt
-Take the belt belt from the pulleys
-Pump at the front loose screw, are three screws, and at the back remove two screws
-unscrew all (3x) hydraulic hoses
- then take out the pump forward/upper
Do I have everything? Where's the belt relaxed?
And the most important thing, can I install this pump without hesitation? The description says it fits...

Do you have any tips?
Thank you very much in advance.

Nunja, habs anders gelöst, eine Schraube musste neu, da ebenfals rund und eine riesige Sauerei hab ich veranstaltet. Aber gut, hab geschafft ist geschafft.
