Most hydraulic pumps for automotive use are very similar in construction. The local libraries carry repair manuals for most autos and I have several that I bought through the years that cover the cars I have owned. Volvo happens to have some excellent shop manuals, written in English, by competent tech writers, unlike MB, which, even if you had the CD you would need an interpreter to understand. Chilton, Clymers and others have 'generic' sections on how to repair these pumps. As in all things hydarulic, fastidious cleanliness is imperative. Any contamination can be very detrimental to the life and reliability of these accessories. A power steering pump failure at highway speeds can be a very disconcerting moment!
These pumps, though simple in construction, are capable of delivering a substantial amount of pressure and a failure of a pressure relief valve will definitely rupture the hoses or seals. I'm not trying to scare you, but just bring some awareness into your intended project.
