Installing an oil change pump

[Nineteen]

Yes I wish the Yanmar had the same setup...

FWIW: Our Nanni converted Kubota diesel has the same little brass extractor pump that is shown in the Beta post. Possibly it comes from Kubota, not from the marinizer.

At any rate, it works well IF you warm up the oil adequately. In cooler places, it can be hard yakka to pump cold oil... all 9 liters of it!

Our Yanmar 4JH3-HTBE has a brass manual pump installed as pictured. Probably put in by the previous owner.

The reason I ask, is it COMPLETLY changed my view of changing oil. Its simple, clean and easy.. No wires, no extra pipes, no nothing. However, I do have a separate oil drain pipe on my MD2030s.

Used one of those for a decade for oil, petrol and antifreeze etc, brilliant bit of kit. Now have the slightly smaller Pela version as its easier to store on board. Doesn't quite have the same suction, so needs a few more pumps as you go along but with warm oil that's fine and gives me time to do other stuff whilst waiting.

Actually need to get a grip and go do an oil change before the winter sets in.

We use it and we like it a lot. We do not leave oil in it but transfer the oil into empty oil jugs if we are not near an oil dump. It's bulky, but I store it on its side in a lazarette (after emptying it), and so far no leaks.

Here's what I have:

1. Switch the transfer pump on at the panel.
2. Attach QR drain/fill hose extension.
3. Open the drain valve on the oil pan.
4. Open the valve at the pump.
5. Suck out the old.
6. Reverse pump and suck in the new.
7. Close valves, tidy up, put everything away.

It's convenient, and I can do it all from the front of the engine.

As to the electric pump.. I went down that path and then stopped at one point and said, "Holy crap, someone must have solved this already". I asked around and was pointed to the pump I listed above.

Same story here. Sold my Reverso electric pump on eBay and use a similar suction container to the WM model shown. I store the suction tubes in a zip loc bag and that works pretty well. No problem laying the container on its side for storage so long as it's mostly empty.

I finally installed my gear pump that is powered by a drill. I think the oil was completely out of there in less than a minute. Works incredibly well, bit overkill but that's the way I roll. I also plan to pipe a tee with valve so I can use a wand to clean out engine pan since the gear drains in there along with some other stuff.

I didn't reverse pump oil into engine although I could have. Doing so would have gotten my hose all oiled up and it's easier for me from top with funnel.

Have one of those beautiful brass hand pumps like the one shown on the Kubota picture here but instead of on the dipstick tube as shown, leaving no way to check the oil level, I screwed a pneumatic hose end to the drain plug hole on the bottom of the oil pan and the other end connected to the cute brass pump when time to change the oil, with it's curved spigot draining into empty milk containers to discard. When done pumping, I disconnect the pump end of the hydraulic hose and plug it with a brass NPT pipe plug and raise it above the dipstick tube level. Then plug the little pump with vinyl hose bent up at both inlet and outlet to avoid drips. Oil filter removal always dribbles a bit. No electricity, no big pump and container to store and can use the dipstick for measuring the level. For $8 bucks, can buy a plastic version of that pump with hoses and all at the H. Depot.

How did you hook it up to the sump?

I would like a reversible one (to fill the engine as well as drain) because access to the top of the engine is restricted.

Our boat came with an oil change system factory installed, so can't really speak to installation other than to say the hoses are attached to drain fittings on the motors and gears.

Greatest thing since sliced bread. Empties our 12 gallons of oil -- both mains, both gears, genset -- in about 10 minutes, and most of that is me redirecting the discharge hose into the next bucket for recycling. Refilling takes only slightly longer, mostly about checking and getting the fill levels right.

Connect your gear and generator, too.

Ours happens to be Oil X-Chang-R brand, but Reverso makes 'em too, probably others.

Yeah, I just did that yesterday

How much I bloody HATE that job

I did relatively well this time -- managed to actually catch all the oil from the oil filter rather than spewing it into the bilge. What numbskull at Yanmar came up with mounting the oil filter horizontally?

And managed not to spill any of the new oil going in. Which is unusual for me.

But I still got nasty black old diesel oil all over myself -- when you take the suction pump tube apart, there's just no way to avoid it. Pull the tube out of the dipstick hole and it naturally flails around


Bah, nasty, ugly, un-environmental job. Next boat will have a reversible oil change pump by all means (like the previous boat did).

I have a reverso gear pump 301 that pumps both ways but never installed it.
Will do so next boat.
I wonder if anyone has ever used it to do a pre-lube on the engine? I guess it would work if it was plumed right. I have nightmares though thinking I'm pre-lubing the engine and really its emptying it into the bilge....

He probably copied it from Perkins/Volvo. Just plain stupid...

I was the service manager at an International Harvester truck and tractor dealership when IH came out with their 86-series of agricultural tractor. The engine oil filters were mounted ‘upside down’ and created a huge mess every oil change. According to the engineers who designed this brilliant installation, it kept lube oil constant during engine starts.

I have wondered if an external lube oil pump could be used not only for removing and replacing engine oil but you could circulate oil after the engine was shut down to help cool turbocharger bearings. Probably not worth it.
