TURNING TORQUE MEASUREMENT
1. Measure turning torque at 360° position.





a. Install steering gear on Tool.
b. Turn stub shaft all the way to right and left several times.





c. Measure turning torque at 360° position from straight-ahead position with Tools.
Turning torque at 360°:
0.20 - 0.90 Nm (2.0 - 92 kg-cm, 1.8 - 8.0 inch lbs.)





d. Measure turning torque at straight-ahead position.
Straight-ahead position is a position where stub shaft is turned 1.93 turns (two full turns and 50°) from lock position.
Turning torque at straight-ahead position: 0.45 - 3.88 Nm (4.6 - 8.2 kg-cm, 4.0 - 7.1 inch lbs.) higher than turning torque at 360°
Maximum turning torque: 1.7 Nm (17.8 kg-cm, 15.0 inch lbs.)
If turning torque is not within specifications, adjust by turning sector shaft adjusting screw.





2. Tighten adjusting screw lock nut with tools.
