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-
tions using following formula.

6) Measure the starting torque of bearing. Make
sure the starting torque is within the specified
range. If the torque is not within specified range, re-
place the roller bearing.
Starting torque:
7.6 — 38.1 N (0.776 — 3.88 kgf, 1.7 — 3.88 kg)
7) Stake the caulking of lock nut at two points.
8) Measure the dimension "B" of drive pinion shaft.
