Muv has some real nice videos - not the same machine as yours but the principles apply - you do not have to disassemble your machine to get it fixed up and working right. Those are a nice simple machine and you should be able to very quickly get it in top working order. Muv has 9 videos on Utube - all time well spent watching.
Glen has info on cleaning up the cabinets. There is also a very old book called 'The Furniture Doctor' by George Grotz - might be of help on the cabinet - if NOTHING else that book is a fun read.
