Spacer Assembly Note

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

Pinion height adjustment 

NOTE:
  • Use the installed spacer when adjusting.

  • Install the spacer with the chamfer on the SST  side.
  1. Assemble the spacer, bearing inner race (rear side), and the SST  (O-ring) to the SST  (49 8531565) as shown in the figure.

  2. Insert the set assembled in Step  1 from the rear side of the differential carrier.
  3. Assemble the SST  (49 8531 567), front bearing, companion flange, and a washer from the front side of the differential carrier.
  4. Tighten the locknut to the extent that the SST  (49 8531 565) can be turned by hand.
  5. Place the SST  (49 8531 565) on top of the SST  (49 0660 555).
  6. Place the SST  on the surface plate and set the dial gauge to zero.

  7. Set the SSTs  as shown in the figure.
  8. Place the measuring probe of the dial gauge at the point where the side bearing is installed in the differential carrier and measure at the lowest position. Measure the left and right sides.

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

Pinion height standard 

0.038 mm (0.0015 in) or less 

NOTE:
  • When the values obtained by the measurements taken in Step  8,  9 are 0.06 mm (0.0024 in), 0.04 mm (0.0016 in) and the tip surface of the drive pinion value is 2, the formula is ((0.06+0.04)/2) - (2/100) = 0.03. Therefore, assemble a spacer 0.03 mm (0.0012) thicker than the currently assembled one. The thickness settings are in increments of 0.015 mm (0.0006), so choose one closest in thickness and install.
