(10) Using following formula, select one to three drive pinion washers.
T (mm) = D − (A + B + C + E − 15) − (0±0.0125)
[T (in) = D − (A + B + C + E − 0.591) − (0±0.0005)]
A: Front roller bearing width
B: Rear roller bearing width
C: Spacer width
D: Height from end face of rear roller bearing inner race to surface plate
E: Depth from end face of front roller bearing inner race to end face of ST
15 mm (0.591 in): Thickness of ST

4. Measure and record the drive pinion shim thickness to be reused.
5. Install the drive pinion shim that is reused for the drive pinion shaft.
6. Using the ST1 and ST2, press-fit the inner race to the drive pinion shaft.

7. Install the drive pinion spacer.
NOTE:
Replace the O-ring with a new part after tooth contact inspection.
8. Install the selected drive pinion washer.
9. Insert the drive pinion shaft into the drive pinion retainer.
CAUTION:
Be careful not to damage the oil seal.
10. Install the inner bearing and lock nut.
NOTE:
• Use a new lock nut.
• Apply differential gear oil to the threaded portion of the drive pinion shaft.
11. Using the ST, tighten the lock nut to the specified torque so that the starting torque of the drive pinion shaft is within the specified range.
CAUTION:
Before inspecting the starting torque, apply differential gear oil to roller of bearing and rotate the bearing several times.
NOTE:
• Tighten the lock nut while directly aligning ST2 and torque wrench.
• If the starting torque is not within the specified range, select the drive pinion washer, and repeat the step until the starting torque is within the specified range.
• When a thicker drive pinion washer is selected, the starting torque decreases. When a thinner drive pinion washer is selected, the starting torque increases.
Starting torque:
5.1 — 17.1 N (0.5 — 1.7 kgf, 1.1 — 3.8 lbf)
| ST1 499787500 | ADAPTER |
| ST2 499787700 | WRENCH |
| ST3 498937110 | HOLDER |
Using the following formula, calculate the tightening torque for a torque wrench.
T2 = L2/(L1 + L2) ? T1
T1: 170 — 250 N·m (17.3 — 25.5 kgf-m, 125.4 — 184.4 ft-lb) [Specified tightening torque range]
