  NOTE: Use a torque wrench with a fulcrum length of 160 mm (6.30 in.)
  
  NOTE: Measure it after rotating the bearing in both clockwise and counter clockwise directions to make it fit.
2. If the preload is too large, replace the bearing spacer with new one.
3. If the preload is too small, repeatedly adjust the preload by tightening the lock nut 5 - 10 degrees at a time until the standard value is obtained.
4. If the preload is insufficient even though the tightening torque of the lock nut exceeds the maximum of the standard value, loosen the lock nut and apply gear oil SAE 90 (GL-5) to the lock nut and the screw thread and the base of the driven pinion. And then repeat the preceding operation. If the tightening torque is smaller than the standard, replace the bearing spacer with new one and adjust it.
