Oil level higher thank filler plug on transfer box?

[warrior]

I'm in the middle of changing my diff and all the oils on my 300 tdi 90.

As I've read I took the filler plugs out first befor the drains, but I removed the filler from the transfer box and oil went everywhere?

Now I've owned this Landy since may and it's had a transfer box befor I got it, is it a simple case of someone has overfilled it befor they fit it?

Or have I missed something?

Could be a few things.....Oil leaking through from the gearbox or if it was grey and gunky then water sucked through output seals.

No looked nice and clean almost new. Just done the gearbox and that was a nasty colour compared with the transfer box so ain't that.

I'd assume just overfilled then

Yep. Fill up a good bit and run the engine and flip the gears. Check level and again.

No on the flat drive way, it's had a transfer box on it befor I bought it and think its been filled up on the look on its back as such,

Took about 2l to the filling plug,

5l of ep80/90 filled both diffs and transfer box perfectly .

Now I have a Detroit locker in the rear and a trutrac in the front. Fresh gearbox oil to,

Just the engine oil to do at some point soon,

In that case, maybe it was on a hill last time it was filled.

Must have been a mountain, it was over a liter I recon, went everywhere including down my sleeve,
