D: ASSEMBLY
1) Measure the dimension "A" of drive pinion shaft.
ST 398643600 GAUGE
2) Using a press, press-fit the new roller bearing
into specified position.
NOTE:
If excessive force is applied to roller bearing, the
roller bearing will not turn easily.
(A) Drive pinion shaft
(B) Roller bearing
3) After fitting a new O-ring to the shaft, attach the
drive pinion collar to shaft.
4) Install the lock washer to drive pinion shaft in
proper direction.

5) Tighten new lock nuts using ST1, ST2 and ST3.
Calculate the lock washer and lock nut specifica-
tion using following formula.
T2 = L2/(L1 + L2) × T1
T1: 116 N⋅m (11.8 kgf-m, 85.3 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST2 length 0.072 m (2.83 in)
L2: Torque wrench length
Example:

NOTE:
Install the ST2 to torque wrench as straight as pos-
sible.

6) Measure the starting torque of bearing. Make
sure the starting torque is within the specification. If
the torque is not within specification, replace the
roller bearing.
Starting torque:
7.6 — 38.1 N (0.776 — 3.88 kgf, 1.7 — 8.6 lbf)
7) Stake the caulking of lock nut at two points.
