TRANSAXLE — Bearing preload adjustment (shim selection)
J2-38prose procedureDiaphragm spring thickness 0.65 mm {0.026 in}; primary shaft subtracts standard clearance, secondary shaft adds tightening amount
Bearing preload adjustment (continued)
- 9Manually expand the selector until it no longer turns by hand.
- 10Verify that both the primary and secondary shafts turn smoothly.
- 11Measure the clearance between the two halves of the SST (selector) around the circumference by using a feeler gauge.
- 12Take the maximum reading and determine the shim to be used. Use no more than two shims.
- 13Install the SST to the differential.

Primary shaft adjustment shim
Subtract the diaphragm spring thickness (0.65 mm, {0.026 in}) from the gap determined in Step 11 for the primary shaft.
Make a shim selection range by subtracting the standard clearance parameters from the result in the previous step.
Select the thinner shim within the range to obtain the standard clearance.
| Specification | Value |
|---|---|
| Standard clearance (primary shaft) | 0—0.05mm {0—0.002 in} |
| Example | 0.57mm {0.022 in} |
| Shim selection range | (0.57 mm {0.022 in}−0.05 mm {0.002 in}) − (0.57 mm {0.022 in}−0 mm {0 in}) = 0.52 mm {0.020 in}−0.57 mm {0.022 in} |
| Shim (primary shaft, example) | 0.55mm {0.022 in} |
Standard clearance (primary shaft)
0—0.05mm {0—0.002 in}
Example
0.57mm {0.022 in}
Shim selection range
(0.57 mm {0.022 in}−0.05 mm {0.002 in}) − (0.57 mm {0.022 in}−0 mm {0 in}) = 0.52 mm {0.020 in}−0.57 mm {0.022 in}
Shim (primary shaft, example)
0.55mm {0.022 in}
Secondary shaft adjustment shim
Subtract the diaphragm spring thickness (0.65 mm {0.026 in}) from the gap determined in Step 11 for the secondary shaft.
Make a shim selection range by adding the standard clearance parameters to the result in the previous step.
Select the thinner shim within the range to obtain the standard clearance.

| Tightening amount (secondary shaft) | 0.03-0.08N·m |
| Example | 0.57mm {0.022 in} |
| Shim selection range | (0.57 mm {0.022 in} + 0.03 mm {0.001 in})−(0.57 mm {0.022 in} + 0.08 mm {0.003 in}) = 0.60 mm {0.024 in}−0.65 mm {0.026 in} |
| Shim (secondary shaft, example) | 0.60mm {0.024 in} |
