Undo the rods and have the piston and rod assemblies out of the top. Remove the cambelt bottom pulley and the bolts holding in the ally end plate, slide the plate off the end of the crank. Undo the bolts holding the main bearing caps and lift them all out, bear in mind the one nearest the clutch will be hardest to remove, so would suggest doing that first. If you've still got the engine upright be careful with these as they're now all that's holding the crank in.
There's a lot of conflicting opinion on whether or not you should hone the bores, i did, a lot of people told me not to bother, a similar number told me it was preferable or essential. I must admit i'm not convinced it was necessary and hasn't just caused me more work. I'd suggest contacting a local engine builder for advice and to get hold parts like bearing shells and rings, they may tell you honing isn't necessary if you use certain rings.
Tips for reduced ballache: When you pull the crank be careful with it, had a lot of people warning me that they're easy to damage. Also, bear in mind all the bearing faces are mild steel, so don't touch with bare hands as it'll rust like mad. I have rusted-in finger prints on my crank thanks to a certain bellend lol. Put all your bolts in seperate compartments or boxes and label them, i've wasted whole days looking for misplaced bolts over the last few months. Spend a lot of time on youtube watching some honing guides, i found a lot of people have different methods and it took me a while to work out exactly how i wanted to do it. If you have a spare block to practice on first, do it! The only advice that was consistent everywhere was don't over-do it - you don't need to remove any material, just create a rough surface for the rings to bed in on.
