Gearbox/transfer case oil change

[DH70]

I changed the gearbox and transfer case oil the weekend and had the recommended amounts at hand, nl. 3.9L Gearbox, 2.2L transfer case, however I only managed to get about 2.5L into the gearbox and 1.2L into the transfer case. The vehicle was raised in the front very slightly and I drained both until empty.
Will it help to raise the back to get more into the transfer case and raise the right side to get more into the gearbox?

Another major issue was getting those 500ml bottles with their short pipe emptied into the gearbox. I ended up taking a plastic hose from my home brewing kit and figured something out. Bit messy, but got the job done. Unless someone can suggest something better, I'm going to make one of these gadgets in this video

Hi Donnie

It's been a long time since I did it, but the setup is with the vehicle parked on level ground, once the oil starts to drip from the top filler hole then it's full.
Adding more might make problems in time.

As for filling issues, I made up a little gizmo years ago when I still had a Land Rover (a.k.a. the dark years )
I took a 1L Consol glass jar, the one with a 2 part lid that seals (outer ring threads on and centre disc is loose fit inside to seal) and I drilled the disc to take a standard tire valve fitting facing outward. The other hole I fitted a brass male to female fitting faced inward that clamped onto the lid (fitting had shoulder on female end and threaded nut that went over the male end). I just can't remember where I got that fitting from or what the name was. I think it was from a hydraulic place.
Anyway, I then fitted a pipe on the inside of the jar that ran to the bottom and threaded into the female on the lid.
What you do is fill the jar with 1L of oil, attach a pipe on top of the jar into the fitting, connect your air compressor to the valve and pump the oil up into the gearbox.
No mess, no fuss and you always know the quantity because it's a 1L jar at a time.

I'll try to dig the contraption out of my garage and take pics. Where it is exactly is a bit of a mystery though.

Another way is to get a large pump bottle like you get those value shampoo's in and attach a hose to the nozzle and manually pump it up.

Haha... I didn't watch the Youtube video until after I posted the reply.
That's basically what I made up.
Works like a charm.

Thought the transfer cas only take 1.5liter?
I also need to change my 4.5's gearbox and transfer case oils.
I got one of those gardening spray bottles with the hand pump. Usually used for pesticides, weed killer, etc.
Attached a tube/pipe to it. Used this to change my bakkies diff oil. Works alright, but i have also wondered if there is not an easier way. (Faster way).
Have also seen someone using a container with a valve attached to it - the use a compressor to pump the oil in.

Donnie, to get all the gearbox oil out the car needs to be pretty level.
