Author Topic: Getting BB cups in (Read 4385 times)

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!

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

Stick the cups in the freezer for a while

Also could do with the same thing matey, I'll have one of your new fangled 'tools' if you have one. Saves waking the neighbours with my hammering at 11pm

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

Yeah original chrome 85 survivor, fooking mint it is

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!!!
