OH My. How quickly I forget things.
Here are a couple of photos of how it connects. I had them in my archive. You need to take off the rear spindle motor covers. The incoming hydraulic pressure hose comes up the rolling conduit. Then you get the birds nest shown. You can see how it splits to the Y and Z tool holder retraction. The pipe you see sticking out of the casting when you have the hose disconnected is free to spin easily. You can see the drilling hole through the top slide is big enough for the pipe fitting to travel through. So I'm fairly sure that if you disconnect like this then you can just pull the whole quill assembly out through the front as I described previously, being careful not to break that pipe. It looks like the long length of pipe simply cantilevers off the rotary joint in the Y quill. I remember thinking it feels like it when I turned it. The hoses hanging around there are all that holds the pipe from spinning when the hoses are connected!
I don't know how to pull the Y quill out. There is nothing to grip on. I could fit a tool holder perhaps, but pulling on that pulls on the retraction claws. Maybe a gentle pull to see if it works.
The other small tube is a sight glass tube for the very front gear selector that engages the Z spindle. So it isn't anything to do with the hydraulics or the Vogel lube system. That gear case is filled via the front orange filler plug. On mine the very long drilling to the sight tube was clogged and it took a lot of rodding out to fix. It's hard to read through the sight hole on the cover when fitted, and a small tilt on the machine would make it misread. I would simply drain and refill the gearbox with the amount in the manual. If you take it's top cover off you can't see the oil. It's down below the gearset in a cavity, but the lower part of the gear dips into it.
Cheers,
