8. Tighten the rear cover so that the torque of the pin-
ion is approx 400 g (14.1 oz). Check with the SST
and a pull gauge.
Caution
Before measuring the torque, rotate the pin-
ion to the left and right a few times to seat the
bearing.
9. Loosen the rear cover and readjust the pinion
torque to 300 g (10.6 oz). Tighten the locknut.

49—69 Nm (5,0—7,0 m-kg, 36—51 ft-lb)
Caution
Recheck the pinion torque after tightening the
locknut. If it is not within 200—350 g (7—12.3
oz), loosen the locknut and adjust once again.
10. Carefully move the rack so that the pinion is set
to the center (neutral position) of the rack gear.
11. Install the roller assembly, needle roller, holder, dish
