When I use a click wrench, I almost always set it about 20% below the
needed settings...one, to take things snug in an orderly manner, and two,
to make certain the wrench is behaving properly... especially on critical
high torque assemblies...

No! I never re-use TTY bolts.   ;)

A more experienced person would've stopped reefing on the bolt in

day..... I could NOT believe that my new never before used torque
wrench could behave in such a manner.

The sprocket (timing belt pulley) appeared fine as did key way in
crank snout. There were no related issues prior.
