I can just imagine!Many dirty words were spoken I am sure.
So... after 2 hours I was able to get 1 - 1/2 funnel full in there. Had to tilt the tractor and use a screwdriver to poke some. I'll leave this till in the morning and cap it off. I think there was a lot of grease still in there. You can see how thick this in on the screw driver.
Need to pick yourself up a rose gun. Works great for shooting heavy oil in.
Although a good search I cant find a rose gun. Being something we use at the mine it's hard to tell what the real name is...had a handle on the back and the other end is open. You stick it down in the oil and pull the plunger back and it fills up the gun. Then stick it in the fill hole and push the plunger in to shoot the oil out. Works great for thick oils that are almost grease.
I just bought what you are describing, a suction gun, got it at Oreilly, part number W54220, $12.99 plus tax. At least I think that is what you are describing. I had an old one with some sort of wrapped metal tube on it, dropped it earlier this year and couldn't fix it proper so I searched and bought another.
Looks similar, same function. The ones we get are solid metal with no hose on the end just an opening for oil to squirt from or be sucked up through.
