S

If the preload is greater than the specification, re-
place the bearing spacer.

S

If the preload is less than the specification, retorque
the nut with 13 N·m (130 kgf·cm, 9 ft·lbf) of torque
at a time until the specified preload is reached.

Torque: 235 N·m (2,400 kgf·cm, 174 ft·lbf) or less

S

If the maximum torque is exceeded while retighten-
ing the nut, replace the bearing spacer and repeat
the preload adjusting procedure. Do not loosen the
pinion nut to reduce the preload.
