Title: Getting BB cups in
Post by: Swivel on April 07, 2011, 08:23 PM
I have the last few bits (just waiting on brake cables now) to add to my 85 to complete it, but the fooking BB cups will not go in!  :tickedoff: I've tried hitting with wood, rubber hammer etc.. I don't have a vice otherwise that may have been the first option. Anymore thoughts of how to get these buggers in!

Thanks,

Matt  ;)

... bit of grease inside the frame BB and around the cups usually does the trick fella  :daumenhoch:

Don't know what you are building, but the internal BB shell is free of paint isn't it?

Take the frame and cups to an engineers place, get them to measure them and machine the cups down for a tight friction fit, not worth forcing them in, they will go, but what if they split the shell?, frame fooked.

might cost a tenner, but I would not want to get a big hammer anywhere near 1985 chrome of that value!!!

x2 or just hold it up in a vice and squeeze 'em in, the monkey metal bearing cup will give before the cro-moly frame, unless its trash.

If the frame had been powder coated that'll be the issue as thats pretty thick compared to wet paint and the cups wouldn't fit ?
