When changing out bottom brackets on the bike, I found our bike uses the SRAM 00.6415.045.0000 AM BB GXP TEAM ENGLISH bottom bracket for the stokers. It is a direct replacement for the stokers bottom bracket, but the captains bottom bracket uses ALMOST the same bottom bracket, BUT the part number for it is 00.6415.045.050, in which the bearings are on opposite side as the stokers. SRAM has discontinued this part (the second one or the captains) and others have suggested pushing the bearings out of the .045 bottom bracket and reinserting them on the other side cups. I hate to push/tap on new bearings.

My question has anyone run into this type of issue and what was their fix?


NOTE: Our cranks are Truvativ Elita GXP cranks and the bike is a CO-Motion Primavera

Thanks in advance.

I don’t have that issue, but I have worked with bearings quite a bit.
depending on the fit, with the cups being aluminum and the bearings being steel you may be able to heat them up in the oven and have the bearings simply drop out with a nice tap. This works surprisingly well for light press situations. If you’re lucky you can reinstall the same way. Hot cups, cold bearings work even better than both being hot, just do let them get crooked!
Pressing the bearings in, assuming a tool just contacting the OD and kept square is a non issue. Pressing them out I agree is a poor choice unless the installation press fit is very light.
If you do have to press one apart, why not just press the old BB apart and then press in new bearings?
