    1. A019O4PE01

      Using SST and a torque wrench, measure the driven pinion preload.

      SST
      09326-20011
      Preload (at Starting)
      Item Preload
      New bearing (without SST) 0.7 to 1.4 N*m (7 to 15 kgf*cm, 6 to 13 in.*lbf)
      New bearing (with SST) 0.5 to 1.0 N*m (5 to 10 kgf*cm, 5 to 9 in.*lbf)
      Reused bearing (without SST) 0.5 to 0.9 N*m (5 to 9 kgf*cm, 4 to 8 in.*lbf)
      Reused bearing (with SST) 0.3 to 0.6 N*m (3 to 6 kgf*cm, 3 to 6 in.*lbf)

      Note


      • The "with SST" torque value is effective when using SST with a fulcrum length of 50 mm (1.97 in.).

      • The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 130 mm (5.12 in.) Click here.

      • The "with SST" torque value is effective when SST is parallel to the torque wrench.

      • If the preload is more than the specification, replace the pinion bearing spacer with a new one.

      • If the preload is not sufficient, adjust the driven pinion by tightening the lock nut 5° to 10° and measuring the preload until the preload is within the specification.

      • Even if the tightening torque of the gear nut exceeds the specified torque, if the preload is insufficient, loosen the gear nut once and apply rust preventive oil or hypoid gear oil to the gear nut and to the screw or bearing surface of the driven pinion. Then perform the procedure again. If the tightening torque is less than the specified torque, replace the pinion bearing spacer with a new one and adjust it.

      • Do not loosen the gear nut to reduce the preload.
