On my 1979 DV36 the hand-start 'option' just involves buying a crank handle (and perhaps a gym membership!). Bukh spares being what they are, the crank handle was about £100 last time I looked, but it's simple enough that someone with engineering skills and equipment could make their own.) On my engine the handle can go in either at the forward end of the engine (top side port), or the aft end, roughly above the gearbox, to suit your installation. A shaft runs between the two ends, and if I recall correctly is connected to the engine by a chain.
I'm not sure that hand-start shaft is now standard, and it, or some substitute, may now be an optional extra.
Ahh! great post, as I could not understand why the plans of a Bukh 2 cylinder turbo diesel show something sticking out over the gearbox. It's a second start handle location!
