Last night I was checking over my bike to get ready to ride this week. I always spin the pedals to make sure there is nothing out of the oridinary.
When doing so last night the left one spun off into my hand. But just the pedal. It left the shaft, and nut still attached to the crank arm. I saw that there are threads inside the pedal "body" or "housing" and on the shaft. So I spun it back on. When I tried to tighten it back down I felt something give and now the pedal free spins on the shaft and I can not get it off to figure out what is wrong with it.
Starting from the crank arm here is how it is set up:
1. The nut that threads into the crank arm, this does not spin of course.
2. Then a washer or spacer.
3. Then another nut where the bearings are housed.
4. Then the pedal itself.
When the pedal spins during normal operation the second nut and pedal spin together. After I felt something give last night they now spin seperatly. This should only happen if just the pedal is to be taken off the shaft. That is not what is happening. And the pedal will not back off again so I can try to determine what is happening with it.
What does anyone think happened? And does it sound like I need to replace the pedals?
Last year I had a accident where I slid on the pavement for about 10 or 12 feet on my left side. It did scar up the pedal pretty bad. But other then the severe scrathces the pedal worked fine. I guess now it is possible some damage was caused internally that I was unaware of until now.
