Shez.sheridan Posted November 3, 2011 Report Share Posted November 3, 2011 Ok guys n' gals, The time has come to service my Profile hub as it's skipping like mad. So I've striped it down (as advised on the profile website).. ..all was going swimmingly until I took the driver off. Inside the driver there are two or three ball bearing races with hemisphere ball bearings - one of which had popped out. I imagine it needs replacing as there were some small shards of metal floating around & it looks like it's been chewed by my rabbit, however I can't find any info whatsoever regarding these ball races online. The other problem is that I do not understand in what configuration the ball bearings go back in as they were all over the shop. I have attached a few images below to help identify the pieces/problem. Cheers in advance for any help. Grazie TF. Quote Link to comment Share on other sites More sharing options...
Azarathal Posted November 3, 2011 Report Share Posted November 3, 2011 Wouldnt those semi-sphere bearings just grind rather than roll? My initial guess is they've all collapsed / sheared in hard but I have no prior experiance with a profile so I'd wait until someone with actual experiance comes along Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted November 3, 2011 Report Share Posted November 3, 2011 you need 2 of these http://www.tartybikes.co.uk/hub_spares/profile_driver_bearing/c22p351.html and clean all that crap off the driver then just obviously remove any bits of old bearing and put the new ones in, be carefull not to loose the little steel shim that sits between the main hub bearing and the driver Quote Link to comment Share on other sites More sharing options...
Azarathal Posted November 3, 2011 Report Share Posted November 3, 2011 So it looks as if the seal on the bearing has come off Wigan? Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted November 3, 2011 Report Share Posted November 3, 2011 (edited) just exploded bearings really they can only take so much i suppose, everything comes to the end of its lifespan and needs replacing eventually Edited November 3, 2011 by WIGAN ??

Shez.sheridan Posted November 3, 2011 Author Report Share Posted November 3, 2011 Cheers guys, Sorry for me asking, so the sealed bearings are a like for like replacement (upgrade - as I imagine they're somewhat unlikely to collapse)? Cheers for the link too, 'tis a while since Ive ordered from Tartybikes.. Dave Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted November 3, 2011 Report Share Posted November 3, 2011 you could probably have a search round for some better quality ones if you wanted too but those ones on tarty will be the standard bearings that come in a profile Quote Link to comment Share on other sites More sharing options...
