I was wondering if any of you are familiar with an electric pump put out by Tecumseh that could be used for extracting oil from an engine without removing the drain plug. I used to work for a gentleman in South Carolina that had this pump and a 5 gallon tank mounted on a pressure washer frame and it was the most wonderful machine for removing oil. I just need to know where I can find a tecumseh dealer that knows what I'm talking about. I've called several dealers in my area and no one seems to know what I'm talking about. Any information I can get would be greatly appreciated. Thanks.

Mower Medic,
If you have shop air, you want to get a MightyVac fluid evacuator. It is a plastic tank that holds about 8 litres. You hook your air hose to it and it creates a vacuum in the tank that will draw the oil out of the motor. I also use it to drain fuel tanks, ect. I never have to remove drain plugs any more. The other day, a push mower came in that was overfilled by about 1/2 qt. Jammed the hose in there and hooked up the air hose and had the fluid level right in about 30 seconds without making a mess. I absolutely love it. Got mine through a local parts store for $94.00. Northern Tool carries them on the web site, but more like $120.00. Let me know if you have any questions about it. MJ

I appreciate the info but I only have an air compressor at work and I was wanting this specific model by tecumseh so I could use it anywhere. I will keep it in mind in the event I can't find what I'm looking for. Having one at work is still better than having none at all, and the price seems very reasonable.

I personally don't like oil extrators. I just don't think that your are going to get all the grit and break-in shaveings or wear shavings for that matter out of the crankcase with one. Suck all the old oil out, too replace the oil with a bunch of grit and such left in the bottom of the crankcase. Does sound like a good way to remove oil if over filled but all we use in that case is a hand siphon pump.

I bought 2 Pela oil extractors for our shop...
not having to pull drain plugs and clean up oil spills has saved us tons of time. i would strongly suggest any one who has not tried one to do so. i also called some of our distributors and asked them there thoughts on oil extractors, they approved.

They also make one that has a hand pump insted of using compressed air. Don't know how it works, but it is also cheaper that the shop-air model. MJ

Arnold; There is a right way and a wrong way to use an oil extractor. First I suck all the old oil out, then I add about 8 oz of kerosene or clean solvent. Then, with the coil wire removed from the spark plug,spin the engine over several times to get all the old oil washed down. Then you suck all that out. Finally you put a small amount of solvent or kerosene in the crankcase ,spin it over some more and drain the remaining small amount into a pan and dispose of it. The main reason I am looking for this particular model is because I work on big spray rigs used for applying herbicides and pesticides and they are usually mounted rather solidly in a truck bed or on a trailer and there isn't enough room to get a pan under the engine to drain the oil without getting oil all over the customer's truck bed or trailer. Thus, it's easier to extract the majority of the oil out and clean it out as described above.

I dont understand what the kerosene does.

 

[mower_medic]

The kerosene washes everything down and breaks down all of the old oil in the crankcase so it leaves the inside of the engine nice and clean. You have to be sure and drain all of the kerosene out prior to adding the new oil.

This just JMO, I've numerous years experience in the mechanical field, but I really wouldn't advise anyone to use kerosene to clean an engine out. Only if you were preparing to disassemble it for a complete rebuild.

You don't want to remove ALL lubricant from the engine, potential for damage ends up rather high.
All you need to do is change the oil before it starts getting really dirty. By volume %, the fresh oil compared to any still dirty oil left by its clinging to rings/walls/etc, is very small.

Have tried various oil removal systems, (Mighty Vac does make a hand pump type too). None live up to the Mfg. bragging of removing ALL oil. Have always been to to drain more afterward by conventional methods.

 

[mach9]

Draining through the drain plug doesn't remove all of the oil either. Remember how much oil was in the last motor you tore down after draining the oil first? And, you probably wouldn't want to extract ALL of the oil and have the motor restart "dry". For what it's worth, I love my oil extractor. Just my .02. MJ

 

[NCSERVICE]

My thoughts exactly Rustic

 

[Arnold]

Mower_medic thanks for letting me know the right way, but I would have to agree with Rustic that Kerosene or a solvet is a no no. I'll keep draining my oil through the plug.

The part number for the complete kit is 670379. It is complete with the tank and pump. Any Tecumseh dealer can get that for you.

 

[mower_medic]

Thank You so much Jman. That was exactly what I was looking for. Thanks to everyone else too for all your help and advice.
