b. Add 0.17 mm (0.0067 in.) to (a).
c. Add 0.22 mm (0.0087 in.) to (a).

Bearing preload adjustment
Adjust the bearing preload of the primary shaft, secondary shaft, and front and center differential by selecting and installing the proper adjustment shim(s).




Primary and secondary shaft gear
1. Install the primary and secondary shaft bearing outer races into the transaxle case (shims removed).




2. As shown in the image, put the outer races into the SST.

NOTE: Turn the selector to eliminate the gap indicated by the arrow in the image.




3. Set the SST (selectors) in place.
4. Mount the primary and secondary shaft gear assemblies onto the SST (selectors).




5. Set the SST (collars) between the transaxle case and the clutch housing, install the SST (bolts) and tighten to the specified torque.

Tightening torque: 37 - 52 N-m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)




6. To seat the bearings, mount the SST (bar) on parts (A) and (B) of the SST (selectors), and turn the selector so the gap is enlarged.
Move the bars by hand until the selector can no longer be turned, and then turn it in the reverse direction until the gap is eliminated.




7. Manually expand the SST (selector) for both shafts until the SST (selector) no longer turns.

NOTE: Make sure that each shaft turns smoothly.




8. Measure the gap of the SST (selector) for both gears.

NOTE:
- Measure the gap around the entire circumference of the SST (selector).
- The number of shims used must not exceed two.




9. Select an appropriate adjustment shim.
1. The shim for the primary shaft gear should be selected by referring to the image and selecting the shim which is nearest (on the thin side) to the value obtained by subtracting the thickness of the diaphragm spring, which goes between the shim and the race, from the measured value of the gap in the SST (selector).

Example: 0.94 mm (0.0370 in.)
0.94 mm (0.0370 in.) - 0.70 mm (0.0276 in.) = 0.24 mm (0.009 in.) [Diaphragm spring]
So the nearest shim (on thin side) to 0.24 mm (0.009 in.) is 0.20 mm (0.008 in.).

2. The shim for the secondary shaft gear should be selected by referring to the image and selecting the shim which is nearest (on the thick side) to the value obtained by subtracting the thickness of the diaphragm spring, which goes between the shim and the race, from the measured value of the gap in the SST (selector).

Example: 0.94 mm (0.0370 in.)
0.94 mm (0.0370 in.) - 0.70 mm (0.0276 in.) = 0.24 mm (0.009 in.) [Diaphragm spring]
So the nearest shim (on thick side) to 0.24 mm (0.009 in.) is 0.25 mm (0.010 in.).




10. Remove the SST (bolts and collars) and then remove the transaxle case, shaft gears and SST (selectors).
11. Remove the bearing outer races for both shafts from the transaxle case.




Front and center differential
1. Install the bearing outer race with the SST.




2. Install the front and center differential and bearing outer race.
3. Set the SST (selector) in place.




4. Set the SST (collars) between the transaxle case and the clutch housing, and install the SST (bolts), and tighten to the specified torque.

Tightening torque: 37 - 52 N-m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)

5. Seat the bearings by turning the SST (selector) with the SST (bar) until the gap is enlarged.




6. Insert the SST.




7. Expand the SST (selector) until the proper preload specification is obtained.

Preload: 2.9 - 3.9 N-m (30 - 40 cm-kg, 26 - 35 in-lb)

NOTE: Measure the gap around the entire circumference of the selector.




8. Measure the gap in the SST (selector).

NOTE: The number of shims used must not exceed three.




9. Select an appropriate adjustment shim to be used for the differential. It should be selected by referring to the image and selecting the shim which is nearest (on thick side) to the largest measured value of the gap in the SST (selector).

Example: 0.54 mm (0.021 in.)
So the nearest shim (on thick side) to 0.54 mm (0.021 in.) is 0.6 mm (0.014 in.).

10. Remove the SST (bolts and collars) and then remove transaxle case.
11. Remove the SST (selector), bearing outer race and front and center differential.




Bearing preload
Verify that the shaft gears and differential bearing preload is correct.

NOTE:
- Verify that the correct adjustment shims were selected.
- If the bearing preload is not within specification, readjust.

1. Set the primary shaft gear and the differential into the clutch housing.




2. Install the selected shim and bearing outer race for the front and center differentials with the SST.




3. Install the selected shim, diaphragm spring and bearing outer race for the primary shaft.
4. Install the transaxle case, and tighten to the specified torque.

Tightening torque: 37 - 52 N-m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)




5. Install the SST through the driveshaft opening.
6. Hook a spring scale to the attachment and measure the preload.

Preload: 2.9 - 3.9 N-m (30 - 40 cm-kg, 26 - 35 in-lb)




7. Remove the SST.
8. With the transaxle facing in the direction shown in the image, install the SST to the primary shaft gear.
9. Measure the preload.

Preload: 0.1 - 0.25 N-m (1.0 - 2.5 cm-kg, 0.87 - 2.18 in-lb)




10. Remove the SST, transaxle case, primary shaft gear and differential.
11. Install the secondary shaft gear and transaxle case, then tighten to the specified torque.

Tightening torque: 37 - 52 N-m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)

Preload: 0.29 - 0.42 N-m (3.0 - 4.3 cm-kg, 2.6 - 3.7 in-lb)
