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.
