Seems I've got myself into a raw deal with an eBay purchase. I made believe I was getting a good deal on an '82 Miyata 1200. I'd anticipated changing out most of the components.... eventually. But it seems not to be even road worthy out of the create. Here's the latest discovery:
I discovered something was awry when I spun the rear wheel and could see the chain bobbing as the cogs wobbled while coasting. You can wiggle the freehub/freewheel (I really can't tell which it is) in and out and around by about a mm. It's loose but doesn't come off. And you can see damage to the slots, which look like someone tried to remove it and tore it up in the process.
It's a 6 spd Shimano 600 HG. I can't tell if it's a freehub or freewheel. How do you remove it?
