This belt is (was =) relatively new, so I think I’ll:
- replace #338 and leave the current belt - to see if it will continue to twist. After it snaps/twists/exhibits some other abnormal behavior, I’ll:
- replace the belt and see if it twists (with new part #338, but old freewheel).
That sequence should give more data about the problem.
What is the recommended torque for bolt #379? I was unable to find it in the manual.
You are right - it might have happened during rear wheel removal and installation in the field, when torque wrench is unavailable.
