The gearbox, engine, and chaincase oils are separate

in the puddle on the floor.

Someone may have been shocked by the rust in the clutch drum and trying to stop it.

Doesn't it have separate oil for the gearbox? As in is it leaking gearbox or engine oil?

Engine Gearbox oil, from the output shaft seal which is behind the sprocket, which is behind the cover plate, which is behind the drive dog, which is behind the clutch basket which is behind ... well you get the idea.

Leaking Engine Oil from the Gearbox?

Indeed, it's leaking oil from the gearbox output shaft seal. That may or may not actually be gearbox oil.

It's also leaking from a number of other places but once the oil's stopped flowing from the output shaft seal which is the main source I'll be able to see how much and hopefully from where.

If you keep going you will be at the other side of the engine!

I think it should be engine oil in the primary chaincase, there may be breather holes drilled into the crankcase behind the rotor as well.

Yes I know! I used to own a T150 and T110 preunit crankcases!

There is no seal between gearbox and primary.
The seal in the backplate prevents oil leaking from the primary.
The sleeve gear bush is, in effect, the seal.
