The first step of any Beogram 400x restoration is usually rebuilding of the arm lowering mechanism and getting the carriage to move properly again. The owner of the Beogram 4004 (5526) that I am currently restoring already cleaned and re-lubricated the arm lowering mechanism, but the linkage between the damper and the arm itself was lacking the retaining washer and the small spring that holds the linkage in place.

One more thing was needed: A lovely new aluminum pulley provided by Nick (use the contact form or send me an email if you wanted one from him - I'd be happy to get you in touch). These pulleys are a great improvement relative to the often wobbly original plastic pulleys. This shows the original pulley:
