HEIDEMANN-Rebuild: Serial #
This is the serial number to the Heidemann bike rebuild I'm currently working on, #7841. Must have been a fairly early production number. Heidemann only made bikes through the early 1960s to early 1990s and Pan Worlds in the early 70's. Note the oversize, drive side bearing cup. I've never seen one that big before. Tried removing it, to clean things, but it is set in place by corrosion, so I left it. Better to leave it than to bend the frame trying to remove the thing. It's smooth as glass in there, the bearing race surface. No scoring. I still managed to clean up the bottom bracket through the other side. Lots of old yuky grease in there. Threads are English, by the way. Bike was made in West Germany during the cold war with a mixture of French, Japanese, English, and German components. A low end bicycle but well put together. (The frame, I've discovered since getting the bike up and rolling, is very stiff. The bottom bracket doesn't sway back and forth when pedaling. That's an indicator of a quality frame set. Strong anyway.)
