I have the same BB/crank on my '07 fuji cross pro. I'm somewhere around 4-5k and it was grinding a tiny bit, so +1 for having a replacement (and the BBT-19 tool) on hand. And related questions for hijack:
My old FSA BB had some green stuff on the drive-side threads, is that thread locker? I'm scraping it out best I can, would some mineral spirits be a good idea? WD-40 didn't do much.
The non-drive side I unscrewed by hand after breaking it free, nice and smooth (no green stuff). The drive-side I still needed the wrench, higher but consistent/smooth level of effort until it was nearly free. I'm assuming this is due to the green stuff and not that the threads have an issue?
New DA 7900 BB has green stuff on it, do I need to add anything else? Aluminum frame. My on-hand options are anti-seize (copper-based?), blue loctite, white lithium grease, teflon tape.
