Disc brakes and wire wheels.<o:p></o:p></p><p class=MsoNormal>Now, I’ve “done” bearings before and maybe did this one wrong last time……<o:p></o:p></p><p class=MsoNormal>So, I took it all apart. No worries.<o:p></o:p></p><p class=MsoNormal>The outer bearing was completely shot. Surprisingly so as there had been very little movement indeed when moving the wheel once off the ground. And no “crunchiness” to the rotation. Certainly no noise or panic inducing anything.<o:p></o:p></p><p class=MsoNormal>I cleaned everything off in white spirit and, once all was pristine and dry, I gave everything a quick look. <o:p></o:p></p><p class=MsoNormal>See item 4, “washer”. The tab on mine had broken off in the groove on the hub. Now, I see that this washer is perhaps better called the “locating washer” when one is looking at the picture for the disc wheel setup. <o:p></o:p></p><p class=MsoNormal>But I don’t really see what the tab is good for……surely the washer can’t rotate once everything is tightened up, shims in situ etcetc? <o:p></o:p></p><p class=MsoNormal>Can the washer have been rotating? Surely not? And could the tab’s fracture have anything to do with the condition of my outer bearing?<o:p></o:p></p><p class=MsoNormal>(The inner bearing seems fine).<o:p></o:p></p><p class=MsoNormal>And, yes, I will get a new washer and I’m replacing both bearings.<o:p></o:p></p><p class=MsoNormal>It’s just curiosity really.<o:p></o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Simon<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
