ok i just drained my gearbox.......was about 1.5 litres in there according to the measurements in the drip tray.

i just put 2 litres of synthetic oil in there.......its not up to the filler plug.

how much does the box hold?

its an old swinger bug box.

ahh its cool its only just below so must be able 2 litres then.

its funny i found a billion places in books websites and on here that tell u what oil to use

no one. mentioned how much

about 2.5 liters...just fill it until it runs out of the filler plug

What ^^ said. don't fill it too quicky though. it could over flow giving the impression that it's full, when really, it's just flowing slowly. Manuals say to fill it with the axels loaded too so you'll get the correct amount in there.. or maybe have the rear axels loaded when you're draining it to get rid of as much dirty oil as possible..
