Trek BB90 Troubles
All,
I have had some troubles with my drivetrain feeling "heavy" so I have been going through bearings and I noticed that the nondrive side bearing cup in the BB was shot. The cup wont rotate more than a tiny bit, I am not sure what this means as I have never dealt with anything other than just rough feeling bearings in a BB. It looks like the crank spindle has just been spinning against the metal shell, creating some serious friction.
So assuming that I need to just replace the cup since it can't be serviced, but I can't seem to pull it out. These cups are supposed to be removable by hand and I was able to pop the drive side out pretty easily and put it back in. The other side is a mystery though.
Has any body experienced this/ does anyone have any suggestions? Should I just try to lightly tap it out with something (not concerned w/ bearing damage re: shot)?
Thanks
