The trick for me will be to recognize the main "story" components out of the 1100 lines of code in 8860.
Both 8860(and your model have only one actor. Actors are used to describe the bone structure of the things moving. This way you won't have to worry about recursion of stuff attached to other stuff.
As it has been a couple of years for me using this stuff myself I went and made the mechanical part of the animation (as far I understand it).
It needs a better story (not just infinite rotation at the starting gear)
But it should get you going a whole lot faster as there is next to nothing documentation wise
