Can a set of slightly oversized or undersized uncaged ball bearings be substituted for the expected size in a threaded heaset? I'm looking for a temporary or maybe even longer term solution to pitting confined to the very narrow raceway of the existing balls. I can't visualize whether the larger or smaller balls might spend all of their time on a fresh raceway.
I'll ask the same question about a bottom bracket with separate cups and axle, too, except that the performance in this location is completely unlike what the balls are doing the headset.

Just uncage the balls and use loose balls and more of them..not smaller or bigger as these will ride in a different place in the cup and cone and hurt them.

Yes, use the same size balls but do not overfill the race. 1 short will run fine, 1 extra botches everything fast. Don't use the wrong size retainer.
If there's visible damage, remove the lower cup and press it back again. That will necessarily cause the dimples on crown race and cup to be misaligned which gives you a half-season to find a new headset. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971
"If there's visible damage, remove the lower cup and press it back again. That will necessarily cause the dimples on crown race and cup to be misaligned which gives you a half-season to find a new headset."
also possible: the new positions following a repack, new bearings and lube, fail completely into an elliptical position where before the bearing surfaces was adequately round and perpendicular. The new elliptic then forces the adjustment, even if held with red locktite and possible welding, into a radically too loose headset assembly. Cure? new headset, new crown race.
