Export thread

So I'm doing an oil change. Get the hose in the fill tube, hook up the air hose and watch the oil start coming up the tube. Turn to get some oil and all of a sudden, I hear what sounds like a bubble burst.
I turned to see the container that the oil dumps in, in an hour glass shape. I thought maybe the line was clogged. But it wasn't.
So with it out of the engine, I turned the air back on, and nothing happened. But within a few seconds, as soon as I drop it back down in the oil, the darn container starts getting thin in the middle.

Anyone ever seen this happen? I'm guessing the container is just too thin of plastic. Even though there's several ridges around it, for strength.


I just checked, and it does the same thing with the hand pump that comes with it.

What extractor do you have? My HF one has a heavy steel tank.

Man up! I use a straw, suck up a mouthful of oil and spit it out...??

I inherited one with the business and when All Power went down the toilet I bought another 6. sold 5 to my riding mates cause it really makes oil changing on old Pommie bikes really easy.
I left the original out side for the bulk of last year when I was not doing much and it has suffered from the UV so it is sitting out back now waiting for me to make a new tank.
But I have had that one for 7 years and heaven only knows how long the previous owner had it .
A real PIA cause I used to be able to do 1/2 dozen oil changes a day with the two of them .
Even better cause I had one set up with the 2nd smallest tube for ride ons and the old one with the smallest tube for walk behinds.
came in really handy for degassing polyeurathane before I cast it

Mine has definitely paid for itself.

EWK 6.5L Pneumatic/Manual Oil Extractor Pump for Automobile Fluids Vacuum Evacuation

Lools like a knock off of a Pela PL-650. I have not seen one of that design that hooked up to a compressor. There is a LOT of external pressure on the container when hooked to a compressor. I started with the little round Pela 6000. Works but roo slow and time consuming for a shop. Since the container kinked it is junk now unless you find a way to splint the outsides so it can't deform.

Once you remove the air line, or turn the valve all, it goes back to it's normal shape.
I've sent an email to EWK, and they responded with some gotcha questions. And this is where I screwed up. I admitted to sucking out oil that was contaminated with gasoline.
So, looks like I'll not be getting a warranty. But, it also looks like I'll be getting the metal one.
I found one that extracts and dispenses. Two way would be easy when there's 5 gallons to dispose of.

looks like the same unit as I am using or a knock off of the same unit.
I asked about a replacement cylinder an they quoted a reasonable price + twice the reasonable price for freight
As it is only a cylinder with flanged at both ends I am looking at turning one up when the big lathe gets commissioned .
I was looking at a length of plastic pressure pipe & through bolting the top & bottom together

If you get some 1x2 sticks the length of the cylinder inside the end flanges and space about 8 of the around it and then wrap the thing top to bottom tightly with duck tape it won't collapse.

What's the duck tape for?

Some schedule 40 PVC might work too, as long as it wasn't too tall. Or for that matter, with the fitting on the top, It's should be pretty easy to make one.

But I ain't got no time for that, at the moment. Maybe a winter project. But I need to have this replaced within the week. Or so i'm thinking.
Before I started this cam job a little after lunch, I used the hand pump, and it worked as long as I didn't pump it more than twice.

You need to make it so it can't deform. Think of it as making a ballon into a zeppelin. The tank just holds oil the sticks and tape make it rigid.

If you can't fix it with duck tape or ketchup it must be an electrical problem.

Is sucks inward. SO wrapping duct tape around the outside isn't going to strengthen it.
Now, if I cut some 1X1's or 2X2's and put then across the middle, at each ridge, that would keep it from sucking inward.

I've found that if I only pump it a couple of times, it don't collapse. But it does take longer to extract the oil. But, this will get me by until I can get steal one.

You don't have a hammer in that list? I'm shocked.

That's just a given.

I use an old fire extinguisher bottle. Looks to be 11ga steel.

Got no photos. I bought a used medical vacuum pump off of Ebay. I think it was like $20 for a Gast brand pump with 1/4HP motor. Gast is a good US-made industrial grade brand. Plumbed it all up with ice maker tubing and a rubber stopper from the hardware store. I've been sucking out engine oil, transmission oil, brake fluid and old gasoline for 5 or 6 years. If the engine is hot, I can drain a car's engine oil faster than I can change the filter out.

Shown is a used 120VAC Gast (brand) medical pump (pressure or vacuum) set up for vacuum. The first several plastic bottles I tried collapsed, then came the idea of using a dead fire extinguisher bottle. Rubber stopper is generic rubber stopper from hardware store. Drill two 1/4" holes in the stopper and insert the two pieces of "ice maker" hose. I've been vacuuming liquids out of engines, brake fluid reservoirs, transaxles, etc, now for 5 years. I'm on my second rubber stopper. Total cost was under $30.

Hope this helps.

That's really cool. The guy who owns the shop here had an old vacuum pump he used to use to extract freon from carrs. He was going to junk it. I wonder if he's still got it. The R12 freon it pumped is outdated now. I'm gonna look around for the pump and see what I can come up with.

Thanks for the idea.

The outdated R12 Freon, is crazy expensive $$$ per lb, & there is still a demand..

Free is always good.
I found that pump on Ebay. They show a lot of used medical equipment, which is often good, but simply outdated. This is stuff resellers buy at auction for pennies, then hope to make money on the microscopes and other expensive items. Often times pumps will do either vacuum or pressure, it simply depends on which port you connect to. You really need to study the photos.

I'm kicking myself in the butt now for not keeping that. It went to the scrap yard. UGH.

I saw vacuum/ pressure pumps (used) on Ebay yesterday starting around $25. Specify "Used", then enter searches like "medical pump", "gast pump", "small pump", "electric pump"....

Should be miles of old medical pumps out there.
Hospitals do not repair things like pumps due to liability problems if they fail .
So all faulty equipment gets sold off.
A friend got a load of bed lifts with leaky seals that he converted to engine lifts before you could get them from China for pennies.
