I am rebuilding a '79 Carlton Professional and it has a period (original I think) Shimano BB.
I removed with the correct tools, cleaned and re-greased, and now can't get the bugger back on!
Firstly I am aware of the reverse thread on the driveside! I have been very careful, not trying to force anything for fear of cross threading, but cannot get the drive side to catch at all. On the other side I can get the BB in about two revolutions by hand and then it stiffens up so that I cannot turn by hand any further. Again I have not applied any force at this stage.
I have had the frame powercoated, but the threads were masked and I have cleaned them up with a rough sponge and WD40. There were no issues with any of the other threads.
Any ideas? Am I be too cautious?
Any help welcom as once the BB is in and the cranks fitted it is almots complete!
