How much oil in Bergen/Wren Gearbox?

Hi Guys

Can someone refresh my memory as to how much oil goes in the Wren/Bergen turbine gearbox. I have scanned the instructions but can't find the details.

Thanks.

Yes, it's 15ml, but please be careful not to put more in! When you try to drain the gearbox and find there didn't seem to be much in there, it's because most of it is coated around the gears. If you put another 15ml in, the gears will churn the oil up and everything overheats. Unless you have a visible leak, it shouldn't be using up the oil so be cautious - it's better to run with less than put too much in.
