headsets w/ loose bearings(4 posts)

I'm having toruble keeping a headset adjusted properly. It's an older 1" threaded headset with loose ball bearings. I've pulled it appart and it looks fine, but when retightening it, it either binds or is loose. Before I pull it apart again, I'm wondering how many bearing should be in each race (just in case that's a problem). What's the standard number of bearings in a 1" threaded headset?
Haven't done one in a long time...did you use new balls?cory

Those things are usually dead reliable--I've had them go for years with no attention at all. There is a little touch involved in getting them adjusted, and it usually takes me a couple of tries.
Could you be reusing the old bearings? Sometimes they get out of round, so when you repack, it can take a couple of adjustments (I've read as many as five, but I have no idea if that's right) before everything gets seated again. If that's the case, you could just keep fiddling or rebuild with new balls (they're cheap at bike shops).
As for the number...as many as fit without crowding ought to do it. Seems to me mine use 11 top and 11 bottom, but it's been a few years. You don't want a big gap, though. If a ball will fit, put it in.
Is your head tube properly faced?Kerry Irons

Has your HS always done this, or did it just crop up. Any "incidents" in the recent past that could have tweaked things? You might check to be sure that your head tube is properly faced and that the HS cups are dead square.

I can't remember the standard number of balls - it may vary with the ball size, too. But I suggest you try it with one ball fewer than you're using now.
