I use the above mentioned BB on a Genesis equilibrium frame for a 386 evo crankset.
Recently had the bearings out and apart for a bit of tlc as one side was a bit rough.
All greased up and put back together correctly, however. . . . .
Once torqued back up in the bb shell it feels notchy again. . . .back off the tension a bit then its smooth again but not torqued up enough in the frame. . . .
Any suggestions?

How do you mean not torqued up enough?
Still loose or not just not to the stated levels?Postby team47b » Sun Jun 28, 2015 11:53 am

yes, its fucked, thats why it was notchy. once its fucked its fucked and needs replacing.
depending on your bottom bracket you might have to replace just the bearings or possibly the whole thing.0 -
Not loose enough to turn by hand but knowhere near the usual torque setting for bb cups. . . . .0

how far off?
whats the range stated on the b/b and what are you doing it up to?Postby team47b » Sun Jun 28, 2015 11:53 am

I get that. But while I had it apart, stripped, degreased then reassembled it felt fine. . . . Still does so long as its not screwed in to anywhere near the recommended torque. . .
I'd expect knackered bearings to feel notchy regardless.0 -

From memory, the range is pretty standard for threaded cups, between 40 to 50 nm and i dont ever do them up much above 40... .0 -
if the range is between 40 and 50 and you're doing it up to 40 then thats fine. 50 is max, not a target.
if in doubt 40 and a dab of Loctite red or similar is fine.Postby team47b » Sun Jun 28, 2015 11:53 am

my experience is once theyre notchy theyre notchy. Or loose.
Like cup and cone bearings and bottom brackets used to be0
