Reposition locking plate (2) so that hole (5) is outside of the circumference of thrust flange (3).
Insert a 3/4 inch square drive through hole (5) so that the square drive contacts the outside of thrust flange (3). The square drive will prevent locking plate (2) from rotating clockwise.
Use a suitable wrench on the square drive to turn thrust flange (3) clockwise until all end play has been removed.
If necessary, turn the thrust flange counterclockwise to line up the holes. Insert the square drive into hole (4) to rotate the thrust flange counterclockwise. Rotate the thrust flange as far as the first correct hole alignment.
Remove the square drive and reposition locking plate (2) and bolts (1).
