Mount locating fixture assembly on opposite side of bearing.  Line up and insert draw rod (8) into connecting sleeve (5) threading the bolt into the sleeve by turning hex nut (on locating fixture side) of draw rod (8) clockwise.  Tighten until rollers are snug against groove lip and locating fixture insert (6) is flush with the face of the bearing outer race and housing Note: Never over tighten causing rollers to dent or make an impression in groove lip Insure that the flat face of the locating fixture insert (6) is the side supporting the bearing and housing.

  5. Turn hex nut (on locating fixture side) of draw rod (8) clockwise approximately 30 degrees causing roller to press against lip.
  6. Rotate roller fixture three complete revolutions or until it rotates without resistance
  7. Repeat steps 5 & 6 above until the draw rod nut (8) is rotated 180 degrees or until the bearing lip is completely swaged and there is no gap between the lip and housing or it meets specification.
