C: ASSEMBLY
1) Measure dimension“A”of the drive pinion shaft.
G3M0462
2) Using a press, force-fit the roller bearing in position.
CAUTION:
Do not change the relative positions of the outer race
and bearing cone.
3) After fitting the O-ring to the shaft, attach the drive pin-
ion collar to the shaft.
CAUTION:
Be careful not to damage the O-ring.
G3M0908
4) Tighten the lock washer and lock nut with ST1.
ST1 498937100 HOLDER
Actual tightening torque:
113±5 N⋅m (11.5±0.5 kg-m, 83.2±3.6 ft-lb)
NOTE:
Pay attention to the orientation of lock washer.
Tightening torque using torque wrench is determined by
the following equation:
T
1=72.2L + 72.2xT
T: Actual tightening torque
Install ST2 to torque wrench as straight as possible.
ST2 499787100 WRENCH
G3M0464
5) Measure the starting torque of the bearing.
Make sure the starting torque is within the specified range.
If out of the allowable range, replace the roller bearing.
Starting torque:
0.3—2.0 N⋅m(3—20 kg-cm, 2.6—17.4 ft-lb)

6) Stake the lock nut securely at two places.
7) Measure dimension“B”of the drive pinion shaft.
8) Determine the thickness t (mm) of the drive pinion shim.
t = 6.5±0.0625 (B A)
NOTE:
The number of shims must be three or less.
