Mechanics and Fixing Any Questions Answered

Assuming it doesn't have flats, if you have mole grips or a pipe wrench you might want to try:

• tape a single layer of inner tube around the exposed, round pedal spindle. Tightly!
  
• position crank at 4 o clock
  
• Allen key in slot, handle pointing backwards
  
• mole/pipe grips on spindle, handle pointing backwards also
  
• grip both tools (awkward reach-around) push down with all your weight
  
  

Careful you don't push towards any chainring teeth. Chain on big ring as a safety measure.
