Attention! When installing the steering gear in a vise, clamp it only at the attachment points. If you clamp the steering gear in other places, you can deform or damage the steering gear housing.
Pic. 13.14. Key usage (1) to check the total torque required to turn the steering gear
2. To check the total torque required to turn the drive gear, use a special wrench to rotate the steering gear within one revolution for 4-6 seconds (pic. 13.14). The nominal value is 0.6 - 1.3 Nm (deviation - 0.4 Nm).
Note. When taking measurements, remove the protective covers from the steering gear housing.
3. Measure the torque required to turn the steering gear at full rack travel.
4. If the measured value does not correspond to the nominal value, first adjust the pressure of the rack stop cover and then recheck the total torque that must be applied to turn the steering gear.
5. If it is not possible to adjust the moment in the usual way, replace the steering gear assembly.
