bearings, cups and sizes - needing some help !
BENDYCAT ELEVENTEEN:
bearing cup is 37mm and it's 9mm deep
the trouble comes when I slide the 19mm axle into a 20mm hole bearing ? it rattles "bump"
when looking at all the 6904 bearings they are 37x9x20mm - so it gains 1mm ???
hence needing the shins that cam with the 90's redline crank that I have but can not get off :2gunsfiring_v1: - yer good luck on that one ::)
so what size are the insides of the new redline bearings then - do they rattle or will a new set just fit right away - prob not as I just thought of that the bear cup will be a different size to what I have - but what size is the hole ?
any ideas peeps ???
john4130:
can't you use a bit of heat to get the old shims off? or a big fookin hammer. ;)
BENDYCAT ELEVENTEEN:
gonna try, but they look well and truly stuck :surprise:
what size is bearing the new redline BB they do on ebay ?
fischflo:
the set rod suggested (10quid) already contains the right bearing AND the right shim to fit a 19mm axle like yours
Whats wrong with that?
b) that shop i suggested may have the shims themselves (3,5gbp) ---- to spare you a few quid in comparison to the (complete)set rod posted a link to ::). i'd just ask if they will fit a redline 19mm axle, and if they still have a set lying around. Personally id go with the ebay set
and: Your lbs might have those shims, too ;)
BENDYCAT ELEVENTEEN:
yer gonna have a look at the one's Rod put up - also Gary posted with a link with some shims
:crazy2: starting to fry my brain looking at bearings :D :uglystupid2: ;D
