macy`d Posted April 4, 2020 Report Share Posted April 4, 2020 Hello I have a mk6 pure with the Spanish style echo urban isis BB. I need to replace the bearings because they feel like gravel. I have only found one post on here on how to remove it but the post is really old and no longer has pictures. can anyone shed some light on how to remove it please? From what I gather I either need to use a puller tool or beat it with a hammer cheers alex Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 4, 2020 Report Share Posted April 4, 2020 Yep, smack one end of the axle with a mallet (not hammer). 1 Quote Link to comment Share on other sites More sharing options...

Rubber or wooden mallet? I see you are currently out of stock as well? Quote Link to comment Share on other sites More sharing options...
Swoofty Posted April 4, 2020 Report Share Posted April 4, 2020 Isis axles have tabs on them that seat against the inside of the bearings. You can hammer on either side to drive out the first bearing. You can use the old axle to drive out the remaining bearing or use a socket large enough to press against the outer bearing race and a socket extension if needed. When you put in the new bearings, a bearing press is ideal, but not 100% necessary. You can use a piece of wood and a 3# mallet to drive the first bearing in the old fashioned way. Some tips on putting the new bearings in: freeze the new bearings at least overnight and use lots of grease on the frame and bearings. You'll need that large socket or a pipe to drive in the 2nd bearing because the axle will be in the way. Good luck! 1 Quote Link to comment Share on other sites More sharing options...

I have a bb press for my mountain bike but that will only work for one bearing, like you say I will have to put the axle in and then tap the second one in. Just need to find a new bb in stock to buy now. thanks for the help Quote Link to comment Share on other sites More sharing options...
