Oil change-drill pump problem YSM12

[Hermit Scott]

I bought one of those pumps at harbor freight that you hook a drill up to and it's supposed to transfer fluids. I got all set up, poured a little oil in the pump to lube it and commenced to easily changing my oil with no mess. Well, there was no mess because no oil ever came out of the engine. I never got the pump to ever work. I tried filling the tube with oil, sucking on it(yuck) and running the pump the other way. I bent a coat hanger and put it in the tube to ensure it would reach the bottom of the crank case.
Has any one used one of these things to transfer oil successfully?

I thought all the oil in the engine got pumped through out the gear case as well. The oil in the gear case looked brand new. IF it is supposed to be pumped through out I have a real problem!

Do you take your oil to a diesel mechanic or an injector shop to have it tested?

Hermit,
I have used a similar drill based pump to empty the oil out of a diesel engine and had no problem. Are you sure you had the direction of your drill in the correct alignment for the pump to pull in the direction you wanted it to go? You may have been pumping air into the oil instead of pulling oil into the air you wanted to fill with your old oil.
Beyond that I do recommend getting a 12V oil pump unit like one of these: http://www.defender.com/product.jsp?path=-1|311|724594&id=830103
Mess is not part of the problem for the most part.
You should be able to remove your old engine oil through either the dipstick hole or the oil fill hole. Once it is easy to do you can do it early and often.
It is also a good idea not to try to pump cold oil out of your engine so warm it up a bit before trying to empty it.

Your gearcase lubrication oil may be separate from the engine oil. That is why it may look good but I bet your engine is dieing for an oil change. Diesels tend to get pretty black oil if not looked after IMHO.

The 4 liter model will do you fine.

$70! That's a weeks pay! I am a cheapo. For now anyway. I need a cheaper solution. But thank you.

I took her for a spin today to warm up the oil. It was an awsome day for sailing. All I needed was a long sleeved shirt. I guess it was about 60F. I saw on Yahoo, some people are getting 2' of snow? That is crazy. I guess this is the only time of year Corpus Christi beats Maine for sailing.

Hermit,
My CAL 2-25 has a YSM12 with unknow total hours. I use a JABSCO "

Little Pal Pump Kit" to change my oil. If you look in your Yanmar manual you will see that the motor capacity is 3 liters and the clutch unit is 3/4 of a liter. The two are NOT connected but use the same type of oil. I use Castrol GTX diesel 15W40. I warm up the motor for about 10 minutes and use the little hand pump to suck directly from the dip stick hole into an empty 4 liter bleach bottle. A piece or two of paper towel to wipe the small suction tube and NO MESS! When not in use, I keep the hand pump in a small plastic bucket wedged between the motor stringers. You will only get about 2 1/2 liters of oil out. Here on the wet west coast we can sail year round and I usually put about 40 to 50 hours on the Yanmar. My engine oil never looks totaly black like some motors but it starts to look dark after about 20 hours even though about 1/2 liter of the "dirty oil" is left behind on an oil change. I normally change the engine oil once a year in the fall and the clutch unit about every third year.

Pela 2000

Get the Pela 2000 oil extractor. Been using it for years, never spill a drop of old oil. Cost about $30.

Hand pump is tried & true, less stuff to monkey with, and plenty fast.
http://www.blackstone-labs.com/ for analysis. ~$20 & they'll send you a sampling container. Lots of info in the report

Steve's oil extractor is worth every penny. 3 steps:

Put tube into dip stick entrance.
Pump handle
Walk away

When you come back the job is done and the oil is in a container ready to be recycled.

Hermit, I use the same pump and process as Jalepeno on my YSM12 and get the same results on how much oil is removed during a change. I insert the pump suction line in through the oil fill cap. I tried one of the electric drill pumps and was not happy with it. I really like the Jabsco Little Pal Pump for the YSM12.

 

[higgs]

Bud-the oil fill cap?

 

[petersea]

My vote is for the hand pump also Jabsco (about $30 if I remember what a paid for it) makes one, pump into a gallon jug and be done with it. Takes less 30 seconds of pumping to empty one gallon of oil. Trust me you will spend more time and effort setting up one of those drill type or electric type pump the it takes to pump it by hand. I think it is an advantage over the vacuum type pump because you pump directly into a empty jug and can dispose of it without transferring from vacuum type pumps. Just my opinion.

 

[Steve Dion]

Hermit: Yes you need to warm up the engine to pump the oil. This is a problem on those YSM engines. They are are difficult to get the oil warm even when the engine is run under load.

Once you oil is warm, you may also experience the vinyl tubes collapsing. The vinyl gets warm and will collapse. If you use a flexible rigid tubing (like the Moeller or Pela) you may have much better luck.

PS: Harbor freight does sell a lot of stuff that is not the best of quality and many of their prices are indicative of the quality. I also shop there.

We use the Jabsco hand pump and I've installed a fitting on the "suck" tube to fit the oil drain hose at the bottom of our oil pan, so no dipstick route is used. I bought one of those hermit pumps years ago and have never used it. hermit, this another one of those "If you'd asked first you would have saved some $$" things. From simply reading this board daily, I've learned about Harbor Freight: tools OK, anything electrical questionable at best.

I bought one of those Jabsco Drill Pump Kits some years ago (when it was half the price West sells it for now....) and never liked it. Seemed like you needed 3 hands to operate it. I switched back to my old brass PAR hand pump and like it much better. The PAR also serves a number of other functions on the boat that the electric pump also can't do well, like draining water from between the hull and hull liner, etc. Yet everyone has their own favorite device for sucking the oil out of their engines. Pick the one that works for you....

I spent years using a hand pump into a milk container. The extractor has changed my life.

If your YSM12 is like my YSE8, and I think it is; You need a fairly small diameter hose to get all the way into the crankcase. I use a $15.00 vacumn pump that I bought at a farm supply store, and it works well with warm oil. I found though, after the first few oil changes, that I wasn't getting out all the oil. I switched to the small diameter hose that came with the pump, and was able to push it another couple inches into the fill tube. I also remove the oil screening/filter assembly, and clean it off.
That seems to get all the old oil out, and leaves the new oil clean at first.

Great video and I like your flip flops! Someday everyone will realize that $70 for an oil extractor is more than worth the money. In the meantime let them pump leaky pumps into milk jugs.
