dann2707 Posted June 11, 2013 Report Share Posted June 11, 2013 Is there any guide or anything to taking apart a trialtech BB to refurb the sealed bearings? They are ropey as hell and would like to know how easy / hard it is. Thanks. Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted June 11, 2013 Report Share Posted June 11, 2013 I will assume Lite ISIS Yes: - Disassemble the BB. - Prise the seals out of the bearings carefully with a fresh Stanley blade. - Rotate the bearing so the little indent in the inner and outer races line up, this will allow the balls to come out. - Sit everything in degreaser for a bit, then wash off and dry. - Re-assemble with decent fresh grease. Note: Notchyness is very unlikely to be solved by the above process; make sure the BB shell on your frame is faced or it will side load the bearing which can cause notchyness. 1 Quote Link to comment Share on other sites More sharing options...

That was just the message that was passed on to me from JAF (It's currently there or I would have provided more info haha) Thanks for that! I'll give it a shot when it arrives tomorrow and report back. Do love to tinker Cheers Ads! 1 Quote Link to comment Share on other sites More sharing options...
dann2707 Posted June 15, 2013 Author Report Share Posted June 15, 2013 It's actually a race not a sport lite! It's mega stuck. The non driveside bearing is really smooth, just the other side seems awful. Help please! Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted June 15, 2013 Report Share Posted June 15, 2013 Stick a new one on, if it's rough / notchy it'll be dented bearing races. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted June 15, 2013 Author Report Share Posted June 15, 2013 I'm struggling to get it out that's the problem - do I have to hit something to release the bearings from the shell?. Should have mentioned that (blame the whiskey) Quote Link to comment Share on other sites More sharing options...
BradJohnson Posted June 15, 2013 Report Share Posted June 15, 2013 I'm struggling to get it out that's the problem - do I have to hit something to release the bearings from the shell?. Should have mentioned that (blame the whiskey) I managed to take apart an onza bb with a hammer and some brute force, greased it all up and put it back together and it was fine since. Man up Dan and give it a good whack! (if it breaks i had nothing to do with it though) Quote Link to comment Share on other sites More sharing options...
