I'm trying to remove a bb that I have not previously before dealt with. The externals are off and one part remains that needs to be removed non-destructively. Here's what I've got: This is installed in a ca. 1950 Terrot touring frame similar to listmember Matt Gorski's. It contained a cottered spindle that fit STronglight cranks which was also threaded on its left side for a cone and locknut for bearing adjustment. After removing the spindle, there were two caps threaded on to male threads turned on each end of the bb shell--this project was handed to me when a friend was hesitant to use Channel Locks on the caps, I made aluminum jaws for my vise and used those to unthread the caps. With the caps removed, there were a felt seal, then a thin steel seal over each set of 7/32" ball bearings. There is a grease port in the bb shell from where I removed a hinged-cap, SA-type oil injector. There is now a thick metal sleeve inside the bb shell with no obvious means of removing it without force. The bearing races are machined into the ends of this sleeve. What is this bottom bracket and how can I remove the inner sleeve without harming it?
Thanks
