Hey guys/girls, I did a search and checked the bible but nobody really touched on what I need to know. It's just a quick question before I go and tackle it.

Where does the gearbox get filled up from and how much oil do I put in it? I've never changed the oil in a gearbox before and just wanna quick description before I do it.

Thanks in advance.

Place zook onto level ground.
Drain the oil using lower bung, once its drained fit bung.
Then remove the bung on the back of the gearbox about halfway up, this is the filler bung, it should be the same size as the drain bung.
Then just fill with oil until it starts overflowing out the bung hole, then its full. Replace bung and drive.

I suggest removing the filler plug before removing the drain plug, just incase you cant get the filler plug off leaving you with no way to fill it back up again. Dont ask how i know this :oops:
