Don't want to strip a left crank pedal thread
So here is my story and question:
I didn't tighten my pedals tightly enough and the left side pedal came out at the end of a 60 mile day. I should have seen it unthreading but I didn't. So when I try to put the pedal in, I can hand thread it about 1/2 way but then need the pedal wrench.
Question: Since I know it should hand thread fully and just need to be tightened with the wrench, should I force the steel pedal thread into the aluminum Campy crank (I can get it cleanly 1/2 way), or should I take it to a shop before I strip the threads?
Thanks in advance.
