Yep - standard EP90 - for both Gearbox and reduction boxes.....

The RGB's take just under half a pint (0.44) - make sure you can get both the fill & drain 17mm hex plugs undone on the RGB's before you drain out the old oil (ask me how I know!)

If i just top up gearbox does the oil find its way to the RGB's?

The oil does flow to the reduction boxes, however the correct way to refill the oil is once eveything is drained from gearbox and both reduction boxes to refill the reduction boxes first, then fill the gearbox until it starts leaking out the filling hole.

I think Ted drained the reduction boxes then couldn't remove the filling plugs, meaning he couldn't fill them back up, so always make sure you remove the filling plugs first from the gearbox and the RGBs before you remove the drain plugs.

0.25 litre in each reduction box and about 2.5 litres in the gearbox.

Yes - on one of my RGB's the fill plug hex was buggered about - which I only realised after I had drained the old oil out!
After about an hour of fretting I finally managed to get it undone - but it was f'ing tight and it was lucky I did finally manage to get it undone as it was in a bad way!
I was sweating a bit I can tell you!

WHS ^^^ Don't overtighten the plugs - they are tapered and you can split the case if you overtighten them. One finger on the spanner is enough.
