Thread: Pump to fill gearbox and transfer

Go the Macnaught oil syringe. It is the best thing I've bought for servicing the car. I hated trying to get oil in the diffs/gearbox before that. It is so easy now.
I've also got a 20L drum pump for when I used to get diff/transfer oil that way.

I have tried many pumps over the years & given them all away.They either fell apart,were painfully slow,or were just messy,& i hate getting covered in oil,particularly gear oil.
I use a lenght of 1/2" clear tube,with a funnel jamed hard in one end.I cable tie the funnel end onto the top of the fence which is next to where i service the vehicles.The other end goes into the Diff,T/B,G/B or whatever. I pour the correct amount of oil into a jug & pour it into the funnel,which then runs by gravity into where you want it.It is a bit slow,particularly in winter,but while doing this there is always something else that needs to be done on the vehicle.You won't be under the vehicle getting covered in oil,& you will hardly spill any.

I use some nondescript suction type thing like the MacNaught suction pump as posted earlier. Most of this style of pump has a screw top to open the complete volume. I unscrew this and tip the oil in. EP90 does not suck and it'll only turn the seal inside out in the pump trying to do so.

Use disposable latex gloves whilst filling and any mess is contained.

I bought one of those simple $15 circular pumps which fits on the end of an electric drill. It's about 3" in diameter. Has flexible vanes which rotate off the central spindle. Inlet and outlet take 3/8" ID plastic hose. It works with gear oil up to 90SAE quite well as well as diesel (NOT PETROL).

I have had it for 20 yrs and used it countless times. Found it works most efficiently with a cordless drill... straight out of the 5L container into the T/F case/diff/AT/engine etc etc e.g to refill the T/f case in the P38 took all of 30 seconds...depending on how fast you run the drill!!

50ml of Dexron 3 is all I use to clean it after use.... AND it packs away easily for long trips...with the cordelss dill...err drill

Yeah, I wasn't advocating any of the suction (syringe type) pumps but rather a good quality hand pump. I've been using a Toledo hand pump (from Supercrap) better than some, but could be better.

Something that is air operated would be the ideal, even a garden sprayer based transfer worked reasonably well, but not very durable.

Thanks all - some good suggestions in that lot.

Was down at Bunnings this morning getting some other stuff, and a $12 cheapie 4L garden sprayer jumped into my trolley. Will give that a go when I do my front diff shortly. Hose is really a bit small in diameter for diff oil but hopefully still works just a bit slower.

In the longer term, I think I'll keep an eye out for a small out of date gas bottle to modify into a decent refiller.

just put a cup full of oil in it first to see if the oil dont dissolve the plastic
