Note:
a.Apply oil to the drive pinion and related parts ahead of time.Then install them and tighten the
assembly to the specified torque.
b.Be sure that the starting torque of the drive pinion meets the specified level.
Starting torque is 8-11 Kgf.m (0.08-0.11KN.cm)
c.After the starting torque has been adjusted to the specified level,crimp the lock of the nut at one
point as illustrated.
d. Be sure that these parts should turn smoothly
When the drive pinion or the ring gear has been replaced, the proper number of shims to be installed
