B6000 lifting arms not operating

[Leetrfd]

That's a really good question???
I know when they add the gearbox they up the fluid from the 9 liters to 10 liters.
I think there was supposed to be a dipstick that was in where the Tee, Nose and Cap are now.

Do you know where I can find any info on that gear box?

I have never seen a manual on that gearbox, but I'll look around and see if I can turn anything up.
