Oil drain hose stuck in the sump via the dipstick hose

So I decided to change the oil on my PC26 which has twin AD31 engines. I tried looking for videos and such but to no avail and figured I'd drain the oil via the dipstick. So I bought a pump system with a hose that slipped straight down the dipstick tube. I gingerly tested it 3 times to make sure it wouldn't get stuck, it came out fine, I put it back down the tube then started pumping. Long story short, the damn hose is stuck in the sump. Apart from lifting the engine and removing the sump does anyone have any ideas about how to remove the hose? there is about 600mm sticking out of the sump and I have already removed the dipstick tube.

As jrudge notes, there's not a lot for it to jamb on, the dipstick-tube ought to be the tightest spot. Did you turn the engine over at all? - even slightly - whilst the tube's been in there? If so a gentle 'rocking' back and forth (by hand on the flywheel/alternator pulley) might release it.
 
Does it go in more ?
If so Perhsps there's a bur on the metal tube bit or orriface inside and a sliver of plastic has cut and now wedged as you have yanked it ,the more yanking the tighter it's become .
So push more in to free that .
Rotate it to move the sliver from the bur gently tease it out -hopefully not cutting another sliver .
Failing that have you rotated it ?

What do you think it is fouling on? There is not much down there to catch on.

You could fill it with oil and see if that releases it ( it came out with oil in before )

Thanks for the reply - I'm not sure TBH. something is directly by the entrance of the dipstick tube in the engine block, not sure what though?

I've been trying to find exploded diagrams to see what's in the sump pan. Marine parts Europe seems to have most of the best images. The oil pump appears to be in the sump from this image https://www.marinepartseurope.com/en/volvo-penta-explodedview-7745910-21-20310D.aspx along with some pipes. So there seems to be plenty of parts to get caught up in. If the pump is in the sump? I'm wondering if the tube has got caught in the gear mesh. I'm assuming the pump is driven by pulleys and belts, so if I loosen off the pulleys, I'll be able to spin the pump and perhaps free the hose, IF, it is caught on that.

First, I'm gonna fill it back up tomorrow and see if it will come out before I start taking anything apart. I really don't want to lift the engine, that would be a nightmare.

Thank you. If filling it back up doesn't work. I'll put a spanner on the flywheel and try rocking the engine.

Thank you, I tried rotating the hose, I can hear it spinning inside and it moves up and down a certain amount then jams. I'm wondering if that movement is slack. It's baffling, to be honest; there is definitely something inside that it is catching on.

Just pull it out with any force needed. You cant really do much about it other than getting the engine out which seems a bit excessive given the issue. Even if a bit of plastic stays in the sump I don't think it will hurt the engine, if it happens ( I don't think it will) it will get stuck in the filter.
 
Oh dear. How frustrating. How long a piece of tube did you insert? Obviously more than the distance to the bottom of the sump. The only moving parts down there in which the tube could get stuck in are those oil pump drive gears but if you can rotate the tube that is very unlikely. The oil pump itself is fully enclosed and the oil pickup pipe has a steel wire mesh so any piece of plastic tube that ends up in the sump if you break it free can't get sucked up into the oil ways.

Very frustrating because you don't need to insert any type of tube down the dipstick tube to extract the oil on any Volvo diesel apart from petrol or the D12. If it's an A prefix engineit has a dedicated drain tube , the B and the P uses the dipstick tube . I'd say it's snagged on the engine block brace .

Does that include the KAD43 and is that what the other flexible hose is coming out of the engine (I know one is coolent)?
I've been dipstick tubing for 15 years!

Yes attach a pipe to the tube , tube goes all the way to the bottom of the dump .
Other black tube is salt water drain from oil cooler

Well I never knew that! Routinely used the dipstick tube on the KAD42's in our last boat!
 
What a pain, can confirm on my AD31P's that there is a dedicated oil drain tube about 6 inches behind the dipstick, difficult to miss!
 
Hey all

I'd just like to say thank you all for the advice and suggestions. The boat is running fine and the oil and filters have all been changed. I have no idea what the tube was snagged on but it was really stuck in there. I tried all the suggestions noted but ended up just giving it a good yank, hence I now have a boat that's back on its feet after some brute force was applied. I have learnt a few things as a result of the experience and advice given and am thankful that i didnt have to remove the engine. She will reach 3700 rpm and 26.8 knts with no smoke or issues....Happy boating!!!!

On my previous KAD32's, regarding the two flexible hoses at the lower left corner of the engine: the one with a blue marking is a seawater drain. The one without a blue marking is a freshwater coolant drain. On my KAD32's, there was no dedicated pipe to remove the oil: it had to come out of the dipstick.

Current D4-260 has a dedicated oil drain pipe.

I use a Pela oil drain pump on my Volvo TAMD41P but the tube I put in the dipstick pipe doesn't reach the bottom of the sump, so I don't get all the oil out. Is Volvo Paul saying there is a better way?
