Have no documentation on the oil used in these gear boxes. Suggestions are
welcome.
There should be one bolt on the side. Take that off and stick your
little finger in there. If there's oil on your finger, it's full enough.
If not, put some more in until it starts to dribble out of the fill hole.
That's it.
In amateur use the gearbox is seldom in use so you could run it
dry for awhile with no damage done. Prop pitches are commonly run dry and
suffer no ill effects.
And I hope you used some cable lubricant like PreLube on the
cables as long as you're at it.
