Sunflower, are you certain it needs stripping and repainting? That sort of industrial machine paint is very hard to get off - it looks to me as though the paint is solid, but a gloss has gone flaky, or the paint has oil or crud build up on it. I am certainly no expert, but just wondering, have you tried just flaking off the cruddy junk?
Anyhow, if you proceed with the full dis-assemble, then WOW, you have my admiration. I've not done such a thing, but from my very minor tinkerings, my only advice would be to take more photos than you think you need. I am always surprised at the details such as orientation of a spring, etc, where photos rescue me after the fact. :-)
Best of luck!
