Yanmar 2YM15 oil change

[Quickstep192 91]

I’m getting ready to do my first oil filter change on a Yanmar 2YM15.
 

Is it as simple as checking to make sure the level is correct, then sucking the old oil put through the dipstick tube and putting back an equal amount?

Put oil pads under the engine in the bilge (because things go wrong). Now would be a good time to change your oil filter, check your racor, check your belts, check the level in the transmission, and check your batteries (water level in each cell).

If you’re using a suction can, run the engine up to operating temperature before starting the suckage. Otherwise the suckage will suck less, which sucks more.

Don't assume that the amount you pull out is the right amount to put back in. Check the dipstick before the oil change. If it's on the money, then you can put back in what you pulled out.

Also, don't assume that the dipstick straw is at the bottom of the sump. Sometimes you can hit a snag going in and think it's fully inserted when it's not. You can also overinsert it and have it curve back up. Either way, you won't get all the old oil out. Right after it starts sucking air, try to push the straw in farther and pull it out partially. If it starts sucking oil again, you'll know you weren't at the bottom.

It helps to wrap a plastic bag over the filter before removing it - crack the filter loose so you can do the rest by hand, wrap the bag around it and unwind the canister - cuts way down on the mess.

Warm up the engine for 10 minutes before pumping.

The oil change instructions in the owners manual seems to indicate that you just connect the oil suction tube to the dipstick tube itself, not a dip tube that goes inside the dipstick tube. This would assume that the dipstick tube goes to or near to the bottom of the oil pan. Anybody know?

the YM engines have a tube for the dip stick that is fastened to the oil drain port with a bango fitting so it picks up oil from the lowest point of the oil sump

Ah, didn't get that. I thought you were using one of those oil suckers that uses a straw that goes down the dipstick tube.

I just changed the oil on mine for the first time. I think it was the easiest oil change I've ever done.

if you really want to do a spectacular oil change just block off the crankcase breather and run it,  few minutes and that dipstick will eject quite a way  followed by a spume of oil..... dont ask me how I know this
