Outer Limits 4x4 Board

Just wondering what people use to refil diff/tcase/gearbox oil during an oil change?

I have used those little hand pumps that cost $2 (for kero I think) but what a pain in the rear that was. Took forevery just to do a diff.

Since I only own real 4x4's I can fit a 5L oil container fitted with a plastic hand pump underneath the car. The smallest filler hole on a Land Rover is 12mm or so so the pump nozzle just fits in.

A good method if you have (less space and) a source of low pressure compressed air is to make a fitting that lets you pressurise an oil container to feed oil in.

Go to a truck part supplier and get (for want of a better decription) an oil syringe.

They are made by MacNaught and a few others and take between half and one litre per load.

Almost as good an invention as bottled beer.

Brilliant!

Sounds like the go. Will check it out tomorrow.

i have heard of using a large tomato sauce bottle and squeezing it in. A cheap mans syringe

i did this last time i did my rear diff, used one of those masterfoods sauce bottles that ya tomato sauce comes in to squeeze the oil in, did take a bit though.

best success i've had is pressurising the oil container and using a hose to get it into the diff/box/transcase

I've used the pumps and also the little filler than comes with most bottles.

Best result i've had is with a 1.25 pepsi max with a heaterhose in the top then a fuel hose in the heater hose, takes 3 mins to fill less than a minute to empty.

Go to a vet. They sell all sorts of different sized syringes. You want one for shoving bulk stuff down horses throats. Pretty cheap too. Otherwise, you can use a bicycle pump, with the tyre connection cut off the end of the hose.

I use a lot of rags, and a well-rehearsed selection of swear words.

I found a $15 "Sludge Pump" in AutoBarn, which is essentially a large syringe designed for transferring (amongst other things) oil into diffs and gearboxes. It's slow and tedious (maybe 200ml a time) but with practise I learned to spill/drip very little.

I quickly learned that oil doesn't like being forced down the little tube they supply, so when you push too hard it blows the hose off the syringe - then the oil comes out real easy but doesn't go where you want it to...

The pressurised container sounds the go - next time I might try it...

Buy your oil in 20 l drums.
Then buy a screw on plunger pump. Had mine for 15 years. Filled 100's of diff, gearboxes etc. Paid for itself over and over

i use an oil syringe, holds about half a litre its great

i use a water bottle with the bottom cut off and a bit of garden hose stuck through the lid, makes a great funnel

oil syringes are great......if you don't mind making a mess and spilling gear oil all over your hands, arms and the ground. I just upgraded to a small hand pump that fits into the 5l containers.

Buy a newer syringe? Mine keeps me nice and clean and even makes coffee.

Well, maybe not the coffee bit.

Pump and drum is good, but not that handy for the 'one vehicle once every sixty thousand k's' lube job owner.

Going by your avatar you don't get 60k out of your rear diff oil/bearings.

before i realised that there were easier ways to refill diff/g-box, and transfers, i had a couple of metres of clear plastic hose (for garden water features etc.) at one end, it was in the g-box/trans/diff, and the other end with a funnel made from a 2ltr coke bottle, up as high as my mate (needs at least one other for this method) could hold it, and poured the oil as i was under the 4B. i think the method is called gravity feed.

the oil only spilt when the box/diff was full, and when you pulled the hose out to stick your thumb on the end of it.

anyway, i have a oil pump/syringe now, a lot better (& easier and sophisticated.....) IF you know how to use one.

Bunnings sell a transfer pump for about $25, they are usually located with the drill bits etc.... the connect into a drill chuck & work very well. i use one at work all the time for draining the last bit out of hydralic tanks. Highly recommend one

this sounds like a good idea

if i did it all the time id probably make up a 10litre container i could pressurise with a half inch hose coming out of it.

but like most people ive done it once and that time i used one of those crappy pumps from autobarn which ya cant push fast or the pump pushes into the bottle and you lose the spring and ball which then takes you half an hour and alot of mess to fix :S

well these pumps seem to last well, they have 1/2" hose barb's so just 1m of hose either side should do the trick, and can be used for any sort of fluid. go 4 it, 4 have u got to loose short of $25

Like to see you pump Cold 90/140 with a drill pump..

Should be able to find a spare syringe around St Klida

Yeah I did this last weekend but it wasn't pretty, Diff Oil all over the garage floor along with that used diff oil smell, wife not impressed.
But I did get some oil in the diff. Funny what we come up.

I use a $1.00 funnel from supacrap autos and a 1 litre old oil bottle. The funnel has a bend in it that fits the filler plug. With 1 litre bottle i know how much goes in. EASY

On my old Landy I just took the transmission hump out (4 tech screws) and used a funnel, lifting the middle seat you could take out the tray underneath and adjust the handbrake, another bung out and you could bleed the clutch

I used to do all sorts of methods to fill diffs and boxes, then got a cheapie oil syringe that made the job ok, but it was only a small one and pumping cold 90 grade diff oil was an effort.

I got a McNaught 500ml syringe this year with a 15mm dia or so pipe and it pumps easily and without mess. These are by far the way to go.

I just did my diffs today... mmmm nothing like the smell of diff oil, gotta be good for your health!.


Looked at gearbox... and werent hrm, not getting a 5lt contained anywhere near that hole!

I like the idea of gravity feeding it in... might try that tuesday

well if u have ever used one u would know that it works fine even with sludge / oil shit. Like i said b4 i use one often to drain the last bit out of hydralic tanks and that usually is pretty thick and it works fine
