repacking bearings....(6 posts)

repacking bearings....tronracer

So last night I dove in and disassembled my hubs, cleaned the bearings and everything else and stuffed as much phil wood ball and bearing grease as would fit back into the old super record hubs. The wheel spins fine and fast still in hand, but after I mounted the wheel back on the bike, it felt quite slow. This is a very simple thing, I put everything back exactly as it was and only hand tightened the first nut. What's up? There's also a pin sized hole in the hub, what do I put in there?

You really don't need that much grease in your hub. But it probably is not the main reason that your hub resists spinning on the bike. It's possible that the bearings are a little tight after the quick-release is clamped down. I don't have any hard data on this but I think the axle/cone assembly can shorten up to 1mm due to the quick release tension. If your hubs feel perfect spinning between your fingers without any play, they will probably be too tight installed on the bike. Leave slight play when adjusting them and they should be just as fast on the bike.

FYI, .1mm (.004") is closer to actual smooshing distance.
Which is quite enough to bind a bearing set. I'll bet your suggestion clears it right up.

Thanks! In consulting the metric ruler, 1mm is definitely a lot of smoosh. .1mm is more realistic.

This helped me get the bearings adjusted correctly.
