5 Determine and note the breakaway torque (friction torque) at the rear axle output shaft using the torquemeter (4).
6 Unscrew marked collared nut and possibly mount new coupling flange.
7 Screw pin wrench onto coupling flange again.
8 Screw on new collared nut and tighten carefully in stages until the value noted previously for the breakaway torque is exceeded by 0.5 Nm.
The breakaway torque (friction torque) must not be corrected by loosening the collared nut!
It is absolutely essential to avoid overtightening the collared nut, otherwise the internal compressed ring collapses and must be replaced.
