Installing new 66T Pulley

Need your opinion. Is it OK to clean loctite from the threads in the old bolts and re-apply loctite and torqe to spec or should I buy new OEM bolts?

I use a wire wheel on a grinder to clean the threads. Look like new.

I know your not supposed to re-use them. I have re-used mine a number of times on a number of bikes. Yeah, wire wheel and blue loc-tite. But that just my experience. You veer from factory recommendations, you take your chances.

It's a bolt that is tightened to a predetermined stretch amount, usually determined by torque or turn of the nut or a combination of both, to near elastic yield strength. This provides more preload on the fastener systems and prevents loosening. Used on high strength joints, automotive head bolts, etc. As the bolts have been stretched from their original use, it is preferred to replace them. That's what little I know, google it. I replaced mine when changing pulleys. Too much work to have them fail or back out to save a few bucks. Your milage may vary.

This guy reused his pulley bolts:

Don't know if he loctited them or not, but wouldn't have mattered. Use new bolts!
