repair book / 424...such a thing?

[clevodrummer]

seeing as my 424 is in the shop and i have evry intention of keeping this thing until death do i part, is there any kind of repair book for 4 tracks or good maintenance books?

Having this thing in the shop really sucks so i want to learn what makes them tick.
