I don't know of a manual but it is not that difficult to separate the generator from the engine.
Remove all the exciter and main brushes, remove the exciter armature, this allows the exciter field frame to be removed from the main generator, the hard part here sometimes is sliding the bearing out from the bearing cage, unbolt the main frame from the engine adapter plate and slide the generator back enough to access the cooling fin bolts being very careful not to damage any windings or the armature, once the armature bolts are out you must rotate the armature 45 degrees to free it from the flywheel.
Here you go, right from the Goddess of SA-200s! :D

I used K's directions above in CEP's link for my first time.
Do you have a digital camera? Take lots of pics as you take it apart, different angles. I have done a few now but I still look back at a picture now and then. Tag all your wires. you never know who may have spliced in a piece of wire of a different color. I once new a lad that rewired everything with white wire and then tye wrapped it all together.No tags, letters or numbers. The customers always said "What a nice guy he was".
Two comments on the instructions
step 14 watch the red and black wires that run from the main generator housing along the bottom of the Exciter Frame to the Exciter Field Coils, they can get hung up.
It can take a, how to say this, quick, sudden, forceful twist to free the dogs from the flywheel. I have a craftsman rubber strap wrench that I got many moons ago. It goes around the armature. Doesn't hurt a thing. Matter of fact its about the only thing it has ever really done well.
