Mojoman Posted May 13, 2012 Share Had an annoying creak on the BB, decided to take it out, clean etc. I have discovered that the plastic inner sleeve is all cracked and looking poinltess! Do I need to have one in there or can I just take it out? If I do need it can you get replacements or is a new BB set required? Link to comment Share on other sites More sharing options...
Thug Posted May 13, 2012 Share I would imagine that the inner sleeve is to prevent water ingress into the bearings. Any LBS should stock spares. Tiny K 1 Link to comment Share on other sites More sharing options...
dirtrider Posted May 13, 2012 Share Mmmm you definitly need it . Without that sleeve you will have some play on the crank . Bst bet would be to get old cups and take the sleeve out , if you do find somebody that stock these sleeves please share . Just remember that the LX (SLX) , xt and xtr sleeves are different !

Mojoman Posted May 14, 2012 Share Here is a pic of how my inner sleeve looks. Wound up buying a new BB set, will service the old ones and put them away as spares. I will also take RockyRuan's offer of a sleeve as well for a spare. Struggled to find anyone who sells Deore BB, had to buy an XT one, why do the LBS's insist on only stocking expensive parts? Not all of us have money to burn....! And why didn't Shimano make a plastic POS like difficult to find and replace? Starting to miss the old Square taper BB!

Mmmmm nou's ek deurmekaar .... why would not having that sleeve in cause more play in the crank? My understanding as per the others (Thug et al) on this thread was that it was only for TRYING to prevent water ingress to the bearings .... And according to other way more 'knowledgable's' on this here expert forum it doesn't even do a good job at that hence the need to 'drill' your BB if you're that way inclined ... So without it your BB would last a 'little' longer but has no 'function' other than that is what I thought ... Link to comment Share on other sites More sharing options...
dirtrider Posted May 14, 2012 Share If you take the sleeve out you got a few mm less inside your BB cup . But I will go and take the good old mircrometer tonight and take pics to explain it better . And trust me I have tried the "no sleeves" BB's !! I got a very messed up crank somewhere to prove it . The sleeve does not go onto the side of the BB but it actually fits inside the BB .

Mojoman Posted May 14, 2012 Share No man , that piece of sheeet I throw away !!!!So i have just blown R365 on an XT set just to get a pointless tube of plastic? Link to comment Share on other sites More sharing options...
Wannabe Posted May 14, 2012 Share So i have just blown R365 on an XT set just to get a pointless tube of plastic? Dunno so much. It must be there for a reason.PING JB, what's the situation with this plastic sleeve? Link to comment Share on other sites More sharing options...
dirtrider Posted May 14, 2012 Share Yes it is there for a reason . It will very nicely collect all the water that happens to get into your BB and then store it there . Been chucking them for years now . I may have few in the workshop for sale ... Lets say R100 for LX and R150 for XT one ? Link to comment Share on other sites More sharing options...
