B16 Cylinder head studs.

The part is #10567, posted above. Unfortunately it isn't in the Fasteners list, which I have. I have the parts book.

I think I tried a M10 coarse nut on the stud. I will check with a thread gauge tomorrow at my friends garage. Meanwhile the work progresses

Engine out and on bench.I need to take bell housing off to remove flywheel so that I can bolt engine to rotating stand but,,,Before I can take off bell housing I need to remove flywheel to get at the two corner bolts. Catch 22. any suggestions? How is the flywheel held onto the shaft. Does the flywheel come off the "flange" marked by arrow or the center spigot

The "bolt" shown in pic#1 isn't a bolt but a locating pin. The same applies to the other side. With the other bolts out, 2 at the top and 2 lower ones each side it should come off. May need a bit of persuasion with a mallet at the bottom. Note: Top two bolts are 40mm long and the other 4, 30mm.

Derek, are you sure about that? Looking at the pic' you can see it's a bolt with a lock washer under the head

Looking at the Pic of bell housing there are two bolts at top but no others visible. Seems strange only two bolts holding it on
I can't find anything about it in manuals

Found this. Looks as though somehow you need to pull flywheel from flange over the studs (the schematic shows bolts) and slide it down so as to be able to undo the the two lower bolts which fasten the bell to the block.I think that I am on a loser when it comes to using my engine stand. Even with the head off the engine will be too heavy to attach to the stand by the gear box mounting holes in the cast aluminum bell housing. I could see a potential disaster in the offing.
I suppose unless there is another solution I will work with the engine lying on it's side.

Item #26 Part #17125 in the picture is called a Styrpinne which is a dowel pin. I suppose someone, even Volvo could have changed this to a bolt and threaded the block but as you have found, that would make life difficult. A dowel pin would have to be short enough to allow the bell housing to move towards the flywheel and then clear it to allow the housing to be lifted upwards. What about the other 4 bolts, 2 per side which are tucked up inside?
As you say you might be able to get a slim ring spanner up inside to do the flywheel bolts one at a time, turn the flywheel to present each bolt as close to the bottom as possible. With the flywheel out all of the housing attachment bolts should be reasonably easy to get at.
Typically I wrote the above and then looked the B16 clutch and flywheel. Pic attached in next post as I can't add it to this edited one.. That shows that once the flywheel retainer bolt nuts are removed you should be able to tap out the bolts and drop the flywheel. From your earlier photo you have already removed the nuts. So maybe you can do that. If you haven't got this info, let me know and I will send it out to you.

B16 Clutch and flywheel.

Thanks, once I was able to look at the schematic and was able to see what I was dealing with everything became clear. Just need some brute strength and persuasion to pry flywheel loose from flange. Just like removing the clutch only more difficult.
