- Use a torque wrench with a fulcrum length of 750 mm (29.53 in).
- Adjust the driven pinion (1) preload.
Note:
• | Use a torque wrench with a fulcrum length of 130 mm (5.12 in). |
• | If the preload is more than the specification, replace the spacer with a new one. |
• | If the preload is not sufficient, adjust the driven pinion by tightening the lock nut by 5-10 degrees and measuring the preload until the preload is within the specification. |
• | Even if the tightening torque of gear nut exceeds the specified torque, if the preload is not enough, loosen the gear nut once and apply rust preventive oil or gear oil to the gear nut and bearing surface of driven pinion. Then perform the procedure
again. If the tightening torque is smaller than the specification, replace the pinon bearing spacer with a new one and retest. |
• | Do not loosen the pinion nut to reduce the preload. |
