• Loosen the bearing mounting bolts and move the tailstock bearing
housing towards the direction of the larger gap until the gap is at the
average value.
• Ensure the bearing housing is perpendicular to the tailstock adapter
within 1/2 degree (a visual check with a square is acceptable).
• Repeat this process until the gap at both positions is within 1 mm. If
moving the bearing housing cannot provide the desired results, the
columns are out of basic alignment and must be repositioned.
• Tighten the bearing mounting bolts to 76 N • m (56 lbf-ft).
