Filling a differential. Give me some ideas.

Go to Wal-Mart, look in the boating section and buy a pump thats used to fill the lower unit on boat engines. It will screw right onto the gear lube bottle and pump it with no mess or waste. Depending on the location of your fill hole you may need a small piece of plastic hose to attach to the end of the pump. Also available at West Marine and Boaters World. Cost is around 7-$10.00. Better yet, if one of your friends owns a boat borrow theirs.
 
I am surprised nobody has mentioned a pail pump yet.

Model 321 is the one I use. It was about $21 years ago, don't know what they are now. I have filled up 4 gallon differentials with it.

Warming up the oil helps a lot. I either put it in the furnace room to warm it up, or place it on top of a heat register or place it on a sunny window.

Since you are doing the differential now, you will end up doing the gear box soon and you can use the pump for that too. Motor oil in 5 gallon pails is sometimes cheaper than buying it in gallon jugs, so that would be another use for the pail pump
 
Well that did not go as planned. I Left the pail out in the sun all morning then drove to work with the heater blowing on it.

Still seemed kinda cool though.

I tried using the siphon hose with the thing on the end that you shake. Wouldn't do a thing.

I took the rattle thing off and by mouth suked on the hose to get it going.

45 minutes later the level in the pail had not moved. The 1/2 hose was just too small.

I pulled it out and got a piece of 3/4 heater hose and a funnel. I stuck the funnel between the frame and an air line and poured the oil into it. Let it drain and did it again.

Took 45 minutes to get all 5 gallons in.
 
Next time rig a funnel out of an old 1 gallon plastic jug with the bottom cut out and some old garden hose. You only have to re-fill it 5-6 times. Just don't let it tip over full or the mess is horrible. Don't ask how I know. An old 2-1/2 gallon plastic gas can with the bottom cut out works too.
