I posted a thread a while ago about descaling my Bukh DV10ME. QLDCruiser replied saying he removed the flywheel to do this job. Iv'e decided I'm going to have to do the same thing, so I will be really happy if someone has done this and can alert me to any pitfalls. It looks like I've got about six Allen screws in the centre of the flywheel, at least they look like Allen screws as there is so much paint on them its hard to make out. So once they are out what then? do I have to knock the flywheel off or jemmy bar it or will a gentle pull be enough?. Is it keyed on or is there a taper? and is it as heavy as it looks? Any help will be greatly appreciated. As you can see I'm out of my comfort zone but determined to do as much of my own work as I can, it's one way of really getting to know my boat. And this forum is such a great way to get info.

I'm not sure if you DV10 is a sail drive or not which would be slightly different than a conventional DV10 with a trans mission mounted on the back
If it looks like this release and remove the alternator belt and remove the Allen key bolts . Do mark the crank shaft and fly when so you can refit the fly wheel in the exact same spot . I probably not that important but I do that and make sure there tight when you refit the fly wheel. There reasonable heavy so loosen all bolts remove all the bolts except one so it wont fall on your toes and if some one is around to under the last bolt while your holding the fly wheel it makes it a little easier .
You might have to lever it a little to get it off
Bunnings sell delicious red in a pressure pack. I think its Wattle
My dv24 had a dowel pin that slots between two of the studs. I did use a rubber mallet to unstick from central hub, i was able to use my feet to (almost) support the weight of it while removing and bolting it up as it is only precariously resting in the hub and dowel pin without studs in place. Definitely heavier than it looks.
It was sort of one of these day going back to the beach
I was on my swing mooring when I removed the fly wheel put it in the dinghy in a very large swell . Don't think Id do that again ever,there fairly heavy items specially when your bouncing around
Thanks HG, yes that is my engine pictured. Sounds like its do-able then, thanks for the warning about it dropping on the toes, and marking the fly and crank. I've tried to nut out how I can get to the cooling water feed into the block without taking the flywheel off but it impossible, so here goes.Thanks all.
Sorry HG am I looking at a DV20 pictured?. The front looks exactly the same as my DV10ME but a closer look seems to reveal two valve lifters and the injector appears to be on the other side.

The photo above is my DV20 Sam. The DV24 which Mangrove has in his boat has the injectors on the opposite side than mine.
Yours would be similar to this motor above
Yes, it's pretty straightforward once you've loosened those allen screws. That will probably require a gentle tap or two with a hammer. Make sure the allen key is well engaged first, you don't want to damage the screws. Might pay to scrape the paint off and tap the key well in before applying torsion. Once the screws are out, the flywheel should come off easily, but remember that it's pretty heavy. Watch your back. And I'm not sure that I actually marked the position on the crank, but it's a good idea to put it back the same way you found it.
Thanks HG. Now that REALLY looks like my engine, little bit shinier but.
Thats a the Bukh diet model I have the fat cat bad boy twin
