Why does the Haynes manual go to great lengths to explain you don't have to remove them to split the cases.
I want to get my cses vapour blasted so they are gonna come out anyway, the manual mkes me feelI'm gonna enter a world of pain: is it such a big deal?

its not so bad if you have the tool to get em off! keep track of where your timing marks are and no big deal!
The Haynes manual is right, but I have always had an easier time getting the crankshaft out of the timing case after the pinion is my experience it has always been easier to take the crankshaft out of the bearing that to get the crank, bearing and pinion out together, even after heating the case. Don't worry about causing yourself any 'pain', the pinion is keyed in place anyhow, so it's really no big deal.

Your right I was thinking the cam wheels for some reason!
The cam wheels are also keyed in place. no worries about getting it back together right!
Still have to get timing all lined up with your intermediate gear when you put it all back together. would hate to see a valve slapping a piston!
Thanks for that; i'm going in!

But i've gotto admit I didn't take too much notice of the timing marks I just figured that 'the book' tells you how to arrange them on the rebuild, so is'cool.

are the 'books' not to be trusted or should i have taken notes just as a belt and braces precaution?
I don't know if you are talking about timing pinions or the crank pinion, this thread seems to be talking about both at different points.
Historically Haynes manuals are at best sketchy, at worst they are misleading, get a decent copy of a factory manual, they are free all over the net and far more detailed.
Crank Pinion ? separating the crank bearing from the outer race was frowned upon by some as it was more likely to get damaged. You have to remember that most of these books were written for workshop "repair" not "rebuild"
Timing pinion ? much easier to leave in place if you just need to split the cases to get to the sludge trap, but then people without pullers try to push the cams through (which works great till the key cuts a nice new key way through the bush.

no manual replaces common sense
