Integrated headset question(s)
I have an 2000 Schwinn Homegrown that hasn't been ridden or maintained in a number of years. The headset (their integrated 'ICBM') is tight not moving very freely. Hopefully, it just needs cleaned, regreased and adjusted, rather than replaced.
Last night I tried removing it, but didn't get very far. I removed the cap bolt and cap, the stem, and a couple of spacers. Beyond that, everything seemed welded.
Should the top seal of the headset just lift off? Because it doesn't want to. I tried giving the fork steerer a couple of knocks with a mallet, but it didn't budge. If it's all bound, should I just hose it down with WD-40 to try breaking it apart, or is there a better way?
