This fan clutch seems to have been used on a lot of Mercedes during the years 1967 to 1985. It is no longer available (or so I am told) but there are still some out there for around $270 new and about $100 used.

It is part number 000 200 04 22 and it is in good working order. The part number is right on the front of it so you can look at yours and read the part number if you use a mirror.

I am asking $50 for it + shipping. It is somewhat heavy for something so small, so if you are in the US shipping ought to be about $15 or so.

I can send photos, but it looks like a fan clutch.
