|   elementary hub rebuild question | wayne
Feb 14, 2002 6:42 AM | | The Spot rear hub on my Y2K Kaboom is making some grinding sounds, leading me to believe it is time for a rebuild. The last time I rebuilt a hub was probably 20 years ago, ball bearings rolling all over the garage. I noted from the webcyclery website that Spot hubs have cartridge bearings. Is rebuilding the hub simply a manner of purchasing the proper cartridge, pulling the old one out, sticking the new one in, greasing it up, and you're done? Or is it more complicated than that? And are there any other tricks or things I need to be aware of? Thanks in advance for your help - this is a great forum. |

If you have all the right "cartridge removal" tools, that makes it easier. I didn't, but I did a good job with a rubber mallet, socket set, quick release skewer, and old car tire. Let me know if you want details. |

Feb 14, 2002 7:41 AM | | Those hubs have a significant flaw in that it is very difficult to seat the bearing catrridges without tightening them down too much. Once you have made that mistake, backing them off is very difficult. I would suggest getting the proper tools to facilitate the process. It will also reduce the chances of destroying the cartridges.

Feb 14, 2002 1:40 PM | | Well, these go back to the old days. These were the Suntour version, if I'm remembering properly. They were used with a standard axel. The springy part was compressed and inserted in the center of the cartridge, then allowed to expand, then the axel and a mallet were used to tap the bearing cartridge out from the inside. The doughnut shaped things were used to allow the mallet to be used for instalation without risking damaging the new cartridges. I know this isn't clear, but I'm finding it hard to describe. It wasn't particularly hard, though.
