Fig. 3—Sector Shaft End-Play Adjustment
      2.   Turn the adjusting screw '"D" down tight, 
      and then back it off until it 
      is free. Then turn the adjusting screw until it lightly contacts 
      the end of the sector 
      shaft.
      3.   Hold the adjusting screw in this position 
      with a screw driver and 
      tighten the lock nut "C" securely.
      To Remove Back-Lash Between 
      Worm and Sector Roller
      1.   Locate the steering gear in the 
      straight-ahead position. This 
      can be done by turning the steering wheel as far as possible in one 
      direction. Then turn it as far 
      as possible in the opposite direction, counting the turns. By turning 
      the wheel back half the number of turns, the steering gear will be in the straight-ahead 
      position. Move the sector shaft back and forth to determine the amount of back-lash between the 
      worm and 
      roller.
      2.   Loosen the three cover to housing bolts 1/4 
      turn, "E," Fig. 4, and the 
      eccentric bolt locknut 1/2 turn, "J," Fig. 4.
      3.    With one wrench on the eccentric bolt, "F," 
      Fig. 5, and another on the 
      eccentric sleeve "G," turn in 
      opposite directions by gradual stages,
