Pumping oil for diffs etc.....

BTW....I just clicked on the link I put up and note that the seller has now upped the price....I only paid $25-85 with free postage. I would NOT be paying the $55- they are now charging!!!

I use a 5 litre Hills weed sprayer. Add a schraeder valve and cut the wand off and use a bike pump to pressurise it to pump gear oil into the diff.
When it starts spilling out all over the floor, release thd pressure and you are done. Usually have to top up the pressure with the bike pump as the oil is transferred. But theres a measure down the side so you know how much has gone in.

G'day,
Been using one of these McNaught brand pumps for filling my diffs Transfer case & gearbox oils for about 30 years & I cant believe its still available although mine holds about 800ml rather than 500ml.
Suction gun 500ml - C16-01.
If the weather is cold & the oil is thick I just unscrew the end & pour the oil in to the cylinder then screw it on & away you go.
Cheers

Can't remember the brand and it's down the shed and I can't be bothered wandering down there in the dark to look.

This design of pump was, and probably still is, used for extracting the old oil from marine engines and gearboxes where it is impractical to get any container large enough under the engine. I'm talking here about a sump that would hold around 80 liters or more.
Basically it is round, about 250 mm dia by 100 mm deep or wide whichever way you want. It has a handle attached to a shaft that protrudes from one side. You just stick the suction hose in the oil container and the delivery hose with a right angle hose fitting on the end into your gearbox, diff or whatever and work the handle back and forth.
It will pump even cold diff/gearbox oil fast enough and with little effort to fill a Land Cruiser diff for example in well under a minute. I made up a small tripod arrangement to mount it on, that sits over a 4 or 5 lt container.
The design has been around for decades. I can remember my late father using a larger version to transfer water from one tank to another.

Get an old fire extinguisher with a flat base, modify the screw out handle.
Braise a tyre valve into the cylinder up near the top.
Fill the cylinder with the required amount of oil.
Hose clip a plastic hose to the trigger mechanism.
Fasten the compressor on the the valve and whooshca the diff will fill in seconds.
Why didn't you think of that ?

Roachie let us know if it works.

But i think you will have better success with one of these,probably put one on my shopping list, sick off using an oil syringe.

What's wrong with a standard old 20l oil drum pump?

I buy both diff and gearbox oil in 20L drums, Roachie, and use one of these Macnaught pumps in each.



When the Boss is not working she kindly operates the pump, while I lie underneath, waiting for the inevitable overflow. :-)

About $35 inc postage

I bought this one from uk seller

Slipped some hose over each port and made a 90 degree elbow that just hooks in to the filler hole
Takes about 3 mins to do 5lts using my rechargeable drill at a slowish speed.

Done all oils on my prado and works a treat.

I use an old nissan Skyline power steering pump which was damaged on a crash. Bolt lug broken off.

$16 grey drill from supercheap is used to drive the shaft of the power steer pump.
Fills Engine, diffs, gearbox etc, easy as, you can also stop, ie no blurting like airpressure systems do) when it is full or overflows. Can reverse if needed to suck a bit back to prevent spillage.

Roachie,
I use an expensive method. Clear plastic tube with a funnel in the top, plus a cheap ball valve near the diff or gearbox end.

I route the tube to get as good a fall as I can and tape the funnel to a step ladder. Pour the oil in the funnel and just wait. Someone can watch the filler and then just turn the valve off when it is full.

Clean up, is drain the excess oil that is in the line back into the oil bottle. Then I bin the cheap plastic hose.

Diffs and axles for road vehicles rarely require any serious quantities, so you don't need a big pump.

I have an antique, cast-iron, diff-and-gearbox pump designed for the old 12-gallon drums, which delivers a measured dose (one pint, as I recall), by rotating the handle until it stops. You then wind the handle backwards and start again for another pint.
It's a great way to measure the exact amount, especially when you know exactly how much the gearbox/diff holds.

However, for road vehicles with small compartments, I utilise a 4 litre plastic bottle and a Septone hand-cleaner metal pump.
These little metal pumps are great, and they work well with heavy gear oils.

Septone hand pump

All you need in addition to the pump, is a length of clear PVC tubing attached to the pump spout - and in a couple of minutes, your diff or gearbox is full, with little spillage.
If you utilise a larger container, and the pump suction tube doesn't reach the bottom of the container, just attach a length of PVC tube to the suction tube.
I just pulled the diff out of my 5-tonne FSR500 Isuzu truck to replace a pinion shaft bearing. The diff holds 5.7 litres, and it only took me a few minutes to fill it right up with the Septone pump and a bottle.
The beauty of this setup is that you can take the whole lot under the vehicle with you, and do it all on a one-man basis.

Cheers, Ron.
