Hello, just bought an old B7100D. Trucker lifted it down from front axel and 3-point lifter. Apparrently something went wrong, because hydraulic doesn't raise or lift anymore. it went down but that was all. There's no force, it's floppy. Any idea/knowledge what break there?

Are you saying it worked before being lifted onto your trailer? There is no down pressure so once the arms are down it will be floppy that part anyway is normal

There is a rod from the 3 point piston to the shaft that rotates and lifts the small arms (rock shaft?) that is not really attached at either end.

I would assume that during the lifting process the arms were forced higher and that rod fell out of position. I think yo should also inspect the upper cover for cracks and breaks. I doubt the designer would think that someone would think lifting as you described would ever be done.

When you move the three point control lever do you hear any noise?

Well your in Finland so I bet it's cold there.
Is it outside in the cold or in a cold shop/garage?
Is there a warm place to move it to?
Or cover it with a heater under the cover?
As it might have water in the hydraulic sump and has frozen.
Warm it up and try it.

If that doesn't work you will need to find if there is any fluid moving through the hydraulic pump.

First check the fluid level in the case.
If that's good, loosen one of the pressure pipe Banjo bolts (yellow).
Crank it you should get fluid flowing.

If not your next step is to drain it and pull the filter screen(blue)

Olet Suomessa, joten siellä on kylmä.
Onko se ulkona kylmässä vai kylmäliikkeessä/autotallissa?
Onko jotain lämmintä paikkaa minne siirtää?
Vai peittääkö se lämmittimellä kannen alla?
Koska siinä saattaa olla vettä hydraulikaivossa ja se on jäätynyt.
Lämmitä ja kokeile.

Jos tämä ei auta, sinun on selvitettävä, liikkuuko hydraulipumpun läpi nestettä.

Tarkista ensin kotelon nestetaso.
Jos se on hyvä, löysää yhtä paineputken Banjo-pultteja (keltainen).
Käynnistä se, niin nesteen pitäisi virrata.

Jos ei, seuraava vaihe on tyhjentää se ja vetää suodatinverkko (sininen)

Thanks for instructions. And jeah, it keeps cold and daylight could be a bit longer, but it's getting better. Just a few frozen months and that's it, coldest months are ahead.

I don't have garage so it's going to be commando style repair, but what doesn't kill,...
Fluids are OK, so I will proceed as instructed.

Surely I have to service the whole thing after it's getting bit warmer.

Reporting back something happens.

Have a nice days in Idaho
