Adjusting Cover Assembly Note

  1. Set the rack to the center position.
  2. Tighten the adjusting cover to 20 N.m {2.0 kgf.m, 15 ft.lbf}. 
  3. Rotate the pinion shaft thoroughly three times to make sure that the pinion shaft and the rack engage smoothly, then loosen the adjusting cover.
  4. Retighten the adjusting cover to 4.9 N.m {0.5 kgf.m, 3.6 ft.lbf}  , then loosen it about 0 to 15° using the SST.

      Center of rack ±90°: 0.98-1.38 N.m {10.0-14.0 kgf.cm, 8.7-12.2 in.lbf} 

      [Pull scale reading: 9.8-13.8 N {1.00-1.40 kgf, 2.21-3.10 lbf}] 

      Except center of rack ±90°: Less than 1.87 N.m {19.1 kgf.cm, 16.6 in.lbf}
