Slacken round nut (1) with pin-wrench adapter, BMW No. 31 6 521, then tighten to 25 Nm.
Turn forks back and forth twice from lock to lock, and leave the forks at the full left lock position.
Mark a 40 mm (1.58 in) arc with adhesive tape or similar (arrow) around the circumference of the locking plate at the steering head.
Align the mark on pin-wrench adapter, BMW No. 31 6 521, with the right-hand end of the marked arc.
Note: 40 mm (1.58 in) around the circumference of the locking plate corresponds to an angle of rotation of 60°.
Turn the round nut clockwise until the pointer on pin-wrench adapter, BMW No. 31 6 521, reaches the left-hand end of the marked arc.
Remove the mark/adhesive tape from the locking plate.
