- Rotate sector shaft adjuster screw counterclockwise until fully extended, then turn clockwise one full turn. Attach INCH-lb. torque wrench to end of stub shaft. Position torque wrench handle in a vertical position. Rotate stub shaft 45 degrees from vertical position in each direction, and record highest reading. See Fig 1.
- Turn adjuster in until torque required to turn stub shaft is 6-10 INCH lbs. (0.7-1.1 N.m) more than reading in step 2. Hold adjuster screw, and tighten lock nut to 20 ft. lbs. (27 N.m).
