Well its actually a scooter...
We have this Norco "curb blaster" scooter that has been in my wife's family since the late 80s I believe. I noticed the steering was a bit "notchy" so I pulled it apart for inspection as i would really like to fix it.
I'm not a bicycle guy so please excuse me if my terminaolgys are incorrect as I'm sure they are.
The races on the lower stem, top and bottom of the headstock look great:
However the race on the top threaded "ring" are chewed up pretty bad:
Just for reference here it is assembled:
It threads onto these threads to tension the bearings and held in place with a lock nut, here it is unscrewed:
The bearings themselves seemed ok visually but there was lots of metallic matter in the grease when I cleaned them so they are probably shot.
Ideally I would purchase a new top ring thing that has the race built into it and new bearings, grease them up well and call it a day but I'm guessing thats not something that is available? I really have no idea and my searching isn't going well but I have not idea how to search this stuff.
Really hoping someone here knows something about this stuff and can help!
The races all seem to be pressed in and I'm sure I can swap them easy enough, I've done it on motorcycles a handful of times however the top ring is the only race that actually looks bad and I'm guessing that will be the hard part?
I do have a lathe, although its not a good one, its clapped out and not worth fixing but I can do some machining with it. I don't think I could cut new races but perhaps I could just machine off the race from the nut and then have a "floating" race under it?
If anyone has any ideas at all please share.
