I have a job that would be made much easier if I could use a fluid extractor instead of taking everything apart to get the oil out. I was wondering, if I could use my HF Brake Bleeder as a fluid extractor for 85, 90-140 wt. gear oil? I have used it on Gas many times and it worked fine but did not know if gear oil would be too much? I need to use a small tube to fit, but it is only about 2 quarts.

I assume you mean their pneumatic bleeder? If so, it would probably work, but it would be slow going especially if the oil is cold, Can you get the end of the hose to where it needs to go?

Back in the day, (late '50s) we used something we called a Suction Gun, it was a tube with a plunger that would **** when you pulled the piston away from the closed end.

Right on the money, plus if the Brake bleeder is use it is contaminated and there for cannot be used for the intended purpose.
Plus the suction gun may be cheaper!

I have a suction gun but its hose is too wide and short to get to the bottom. I could rig up adaptors but when I pull the suction gun, I could not get that much oil out every stroke. That is why I want to use the brake bleeder, I could use let it run until I had a quart.

I’ve used the brake bleeder to extract fluid from small reservoirs but you really want something like this…
they sell a similar product at HF that I’m sure works fine and maybe even cheaper.

I use it to **** the oil out of my generator. Saves on clean up

Ive used a vacuum brake bleeder to **** out diff oil and it took FOREVER.
I've never used it for a heavy weight oil like that, but yes, I used to have one in the shop and used it constantly to evacuate reservoirs (brake fluid, power steering, even coolant). You can even put it down a dipstick tube sometimes.

It needs to be warm first. Just like engine oil.
While the numbers are way higher, gear oil isn't all that much thicker than motor oil. They work off different charts.

i beg to differ.
75w140 is wayyyyyyyyyyyyyyyyyyyyyy thicker than 15w40 when its 35 degrees out

You can feel the 15% difference? Un huh.

I have and have used the Holt bleeder below for gear oil and it works fine. The warmer the fluid the better. If you have a small heater like a Mr. Heater Buddy heater or a torpedo heater, you can jack the vehicle up and then aim the heater at the differential and let it run for awhile.

Just an update, I bought a MightyVav air power fluid extractor. I needed to use the smallest tubing I could buy so I could get it into the bottom. I created a vacuum, turned my air off and let it **** all night. It worked fine!!! The limiting factor was how far could I get the tubing in.
