Torquing drive shaft bolts

[Zombie Master]

When you are tightening a bolt with a torque wrench, you are working against the sliding coefficient of friction until you hit your goal. Say at 25 Ft Lb. To loosen that same bolt you have to overcome the static coefficient of friction to start the bolt moving. It may take 28-30 ft lb to start the bolt moving. So, the break away torque is a good bit higher than the torque required to get to the target torque. With a beam type wrench its easy to test this.

I'll keep that in mind....thanx!

Still, we nearly always used a beam type to loosen critical fasteners, as a form of diagnostics.

Those clicker types are not good for much. They are good for hard to reach places, but on a motorcycle we don't really have them.
