Guys I have some problems with my bottom bracket here.
I think I have cross threaded my bottom bracket shell,
the bottom bracket cannot get into the shell correctly, it always misaligned itself after a few turns,
if I forced it to align properly, it will not fit into it at all, the after one turn it will pop up itself,
after studying to the threads, I came up with this :
Red color - Cross threaded line
Yellow color - original line where it should be
Is it possible to rechase the threads?
or can I sand off the first 3 rows of threads and still remain usable?
