Diff oil fill easy peasy

[myJagV12]

Hi Jagies,
I just filled up my differential and although a little afraid before it turned out to be done in 10+2 minutes (2 minutes to clean the overfill).

I have used a very cheap (~15€) equipment from Einhell (#3407000 Petrol and oil suction pump), a UNC nut and a compressor as you can see on the pics. In winter you might want to warm up the oil before a little.

It has a conical rubber cap with a conical hole to push the 6x9 pipe through. You simply have to push the cap down while pressurizing and give the oil some time in between. The bottle was large enough for a complete fill if you fill it up ~3/4. If you apply too much pressure you will feel it on the rubber cap and see the bottle expanding but before it exploded it would press the rubber out.

Maybe this helps some and you might use the equipment for suction purposes or bleeding as well ;-)
Kind Regards,
Tom

Heaven for diff oil fillers at least !

Handy piece of equipment. For filling differentials and transmissions with difficult to access fill holes I use an oil pump attached to a bottle of oil that was used to fill the lower unit on an outboard boat motor. I just stick the hose into the hole and pump away until oil starts to drip out of the access hole. Bob's yer uncle!
