SST

0 Assemble the bearing adjusting screw, then adjust the bearing preload by gradually tightening the screw with SST. SST [09616-22010]

Before adjusting the preload, tighten the screw to snug down the bearing.

Fig. 8-187

Fig. 8-187

Measure the bearing preload with SST and a torque meter.

SST [09616-00010]

Check to see that both the right and left rotations are identical.

Tighten the lock nut with SST. SST [09616-22010] [09617-22010]

Tightening torque: 23.0-26.0 kg-m (167-188 ft-lb)

After tightening the lock nut, make sure that the bearing preload has not changed. SST [09616-00010]

0Set the ball nut at center of the worm and insert the sector shaft into gear housing.

Insure that the center teeth of the ball nut and sector shaft are meshing.

0 Assemble the sector shaft end cover with the adjusting screw and thrust washer. 1 Before tightening the set bolts, completely loosen the adjusting screw with a screwdriver.

2. Coat the sealer on the thread and tighten the bolts.

Tightening torque:

Set in the neutral position of the worm shaft and place matchmarks on the worm shaft.

Count the total number of worm shaft rotations and turn back half of the total number from one end to determine the neutral position.

Fig. 8-194

Adjust the overall preload with the adjusting screw at the neutral position. Measure the preload with SST. SST [09616-00010]

Preload (starting): 8-11 kg-cm

Preload measurement should be made with the meshing in the center (neutral) position.

Install the pitman arm and slightly tighten the nut.

Align the matchmarks on the pitman arm and sector shaft.

Measure the sector shaft backlash. - Note -

Sector shaft should have no backlash within 100 degrees on the left and right side of neutral position.

After checking the backlash, remove the pitman arm
