I can't locate those FB details PMK. Can you please post a pic of how/what you tied the head of the bolt to. Thank you.


EDIT: I now understand The pulley face on your machine has holes to loop the wire thru. The early ones did not.

There now, my inquiring mind is more understanding. And the best substitute for brains is .......silence.

When fretting has take place, tension on the bolt will be reduced, enabling the rate of wear to increase. But the bolt shouldn't fall out even without the wire tie due to the factory applied thread locker on it, unless it's been a reused bolt. However, I've seen a pic of where the bolt has broken off due to the pulley being so loose.
