3. Secure the SST  with the O-ring. Install this assembly in the carrier.
4. Install the bearing inner race (front bearing), the SST  , companion flange, washer, and nut.
5. Tighten the nut just enough so that the companion flange can still be turned by hand.
6. Place the SST  on the surface plate and set the dial indicator to "Zero".

7. Place the SST  atop the drive pinion model. Set the gauge body atop the gauge block.
8. Place the feeler of the dial indicator so that it contacts where the bearing inner race (side bearing) is installed in the carrier. Measure the lowest position on the left and right sides of the carrier.

   NOTE:

   • The number is inscribed on the end of the drive pinion.
9. Add the 2 (left and right) values obtained by the measurements taken in step (8), and then divide the total by 2.From this result, subtract the result obtained by dividing the number inscribed on the end surface of the drive pinion by 100.(If there is no figure inscribed, use 0.) This is the pinion height adjustment value.
