Showing how I verified the applied torque to achieve the 15# plus 85 degree tightening method.
Discussed the factory tightening procedure, clamping force, bolt fatigue and how it can affect the clamping force.
My results showed the bolts are torqued to 50 ftlb after following the factory procedure.
Sloppy Mechanics digital torque wrench indicates the final rod bolt torque to be between 51-53 ftlb.
It shows there is a wide variance of accuracy using degrees to final torque. You will get more consistent clamping by using a torque wrench especially when re-using a TTA fastener.
