    Hollowtech II Bottom Bracket Installation Issues

    Hi, so I decided to take off my bottom bracket since I wanted to give it a regrease but when I tried to reinstall it, I found out that it kept slanting and required a lot of force when trying to install the drive side cup so I thought that maybe it was because my bottom bracket being worn so I went and got a new one and guess what; same issue. It keeps slanting and requires more force than I think is required. Whenever I watch installation videos, I see that the mechanic can install it in with his hands with not much force but when I try to do that I cannot, I'm scared of tightening it further because I'm afraid that I will damage the threads on my frame. I've got no idea what to do and I'm kind of lost

    Thank you for reading

    Sounds like it might be cross threaded, you are correct to not force it. I would have a shop re-tap and clean up the threads, might solve it for you

    Yup that's what I'm thinking.. A few threads are crushing each other so I'm going to go find a shop to help with it since I can't afford the tools to do it. Thanks for the reply!

    You are turning the BB cup to the left to tighten it?
