Ur-q gearbox oil

[Jim Haseltine]

Anybody - what's the refill oil capacity of an Ur-q APX gearbox?
I think the full capacity is 3.2 litres so I'd expect the refill to be
around 3. What I've drained out is nothing like that, 2-2.5 at best and its
not pleasant stuff, brown/black and stinks - rather a lot of foam too so I'm
guessing that the slight noise from the gearbox was down to it being low on
oil.
