2. Measure the length from the pinion shaft center to the crescent wrench end (application point of pull scale) as shown in the figure. This is dimension A.
3. The rotation torque of the pinion shaft can be calculated using the following formula: Measured value using pull scale (N {kgf, lbf}) = rotation torque of the pinion shaft (N.m {kgf.cm, in.lbf})/length A (m {cm, in})

  Pinion shaft rotation torque (center of rack ± 90°)
  
  0.88-1.48 N.m {8.98-15.0 kgf.cm, 7.79-13.0 in.lbf}
  
  [Pull scale reading: 0.88-1.48 N.m {8.98-15.0 kgf.cm, 7.79-13.0 in.lbf}/A (m {cm, in})]
If not as specified, remove the locknut and adjust the adjust cover.
