A question on the Samba about the “interchangeability” of horn contact rings made me get off my duff and fix a nagging problem of intermittent horn function on my ’86 Syncro. Someone in the past had made a fairly neat fix with copper wire to form a contact ring, but it only worked when steering wheel at a certain angle 🙂
I had a known good ring on the steering wheel of my ’82 Westy, so I whipped both wheels off, 24 mm socket (15/16″ also works) on nut, and swapped the contact rings. direct fit, no problems even though the steering wheels themselves are different. You just pry the ring out with a flat bladed screwdriver. Pics below show the two wheels and the home made contact ring. The larger of the two wheels is, of course, from the non power steering ’82.
