Changing & topping up Diff Oil

Tannks David will check it out.

I use a set-up that was adapted from a truck's air tank. It has a screw lid off a 44 gallon drum at the top for filling, a air inlet to match my compressor, a gauge on the side and an outlet on the bottom with about 3 meters of hose and a 45 degree turn tap near the end of the hose.
Put the oil in, replace the lid, pump up to about 25 psi, get yourself in position under diff, gearbox, tranny case (or in the engine bay if doing motor oil), turn tap and watch the oil go through.........no worries.

I find one of those drill driven rotary pumps with some plastic hose very simple and easy to use.

Davie,
Since you like the product, and use ExplorOz, why not tell them to advertise their product here as you seem to think our audience and the discussions are well suited. That would be a great referal for us.

I noticed from their website that they are based in Perth, so that makes talking to them (for me) very easy. Are you in Perth too?

I managed to get a 4lt bottle of Castrol diff oil and it come with a small hand pump which screwed into the top, replacing the lid. Toping up the gear box or diff can be done from under the vehicle. I take it away with me on big trips, just in case. It is a little slow but does not make a mess.

Some one else said once before that a washed out agricultural sprayer with the nozzle removed to give an open hose works a treat. You pump up the pressure and pull the trigger. Not used it myself I use the old fashion 750ml syringe. Sprayer sounded interesting though I thought I might give it a try myself next time.

Some of the retail one litre gear oil packs have a pull out spout which allows you to squeeze in the right amount to your diff or gear box. Obviously for a refill you may need a few packs but probably about the same as buying 4 litres.

I use the Tom Thumb variety . Holds 1 litre, fits in rear drawers beautifully and
cost less than $20 from Supercheap etc

I haven't changed the diff and gear box oils in 6 years. I check them all once a year or if I have been through lots of water. The transfer box leaks through the output shaft. When it stops dripping it is time to top up. I use a ordinary plastic 1 litre oil container and have a flexible nozzle which I fit to it. Cost $1 at the cheap shop. The transfer case leaks about 1 litre in 10,000km.

Just for the record I use a pump made from an old shocker, you cut the case open and use the piston and barrel to make up a pump, solder the piston valves shut and solder a hose fitting onto the bottom valves, works realy well, you can use it like a suction pump to empty out things like you power stearing.
