Rear pulley: Do you re-torque yours?

Bolts stretch when torqued to create a clamp load on the parts being assembled. If they are over stretched or repeatedly stretch the bolt material will yield in it's molecular structure and fail to provide the required clamp load. All this being said some bolts are one time use and some are multiple use. If the manual says change them every time then by all means change them. If it says to change them after 3 times then you are safe to use them 3 times. You can always err on the side of safety and treat them as one time use only and change the bolts any time they are removed.
The sharpy marking trick Nomadmax mentioned would eliminate any need to re-torque them just to be checking the bolts.
