I think there'd be just as many things to undo & remove to turn the bike upside down as there would be removing the engine. For a temporary fix, couldn't you just do what the PO did? From your description, it sounds like the crack is in the thread, not right through the bottom cover, so would it be possible to weld up the crack & recut the thread? With care, it could be done without stripping the engine. I had a similar problem on a boat engine - the plug was rusted in & in trying to remove it, the threaded boss in the sump cracked off. I had the hole brazed up & use a suction pump to suck the oil out. This is normal practise in boat engines as they're usually sat mm above the sole (boat speak for 'floor'), and there's no space under the engine to drain the oil. Sucking the oil out a low reving agricultural diesel is one thing, not sure I'd want to do that on a bike engine. Mind you, on the SD engine, I've found the last dregs come out when you remove the clutch cover, not the sump plug!

Yes, I have been thinking about that, the thread is cracked on three different spots, roughly the same distance apart. I did cut into them today with a dremel and a diamond bit and put some JB in there. Screwed the bolt in a bit later with a copious amount of silicone oil on the threads in order it not to stick, and undone it a bit later. It looks like OK for now, will try tomorrow torquing it down. The main reason I would like to remove the cover is for the constant fear, that a hardened piece of a broken tool is floating in there possibly seizing the engine in the most unwelcome of situations - miles from home doing 70 mph on the motorway... The PO fixed the problem - kind of, the engine was slightly dripping, which causes a constant hassle, as I park the bike in a common passageway. I could in theory glue in the whole thing, bolt, thread, washer, everything, but sucking the oil would leave all the sludge behind. You are right about the lutch cover removal though - in front of the most arsy of neighbours I managed to spill a nice amount of oil on the concrete floor, when removing it  BTW turning the bike over you would "only" need to remove the exhaust box, two or three of the retainers and possibly the speedo-tacho assembly. Otherwise it is disconnecting everything (being ham-fisted, I would manage to render the bike unusable), removing the carbs (again), taking of pipes, exhaust box, footrests, all sorts. But again, I never tried to turn a 185 kg bike on it's head, only my bicycle. I am sure, I would damage something in the process.... Gosh, I wish that stupid broken tool wouldn't be in there (might not even be) |

Damage to the upper parts of the bike due to the weight aside ,there is also a very high probability the bike will fall on you as you work on the bottom end, I would'nt reccomend it

I just try to make it work, knowing very well, I will do the proper procedure at the end... Anyway, what about flushing the system with pwtrol? I mean pouring a litre or two instead of oil, shaking the bike and getting the oily petrol out whilst leaning the bike towards the oil plug? Or is that stupid, wastage of petrol and it wouldn't work? |

Not a good plan you may get all the petrol out but fumes will remain and your engine could explode between your legs

Great pospects To remove the lower crankcase is it enough to take the side covers off, or do you have to remove the clutch, generator, etc? |
