Tolerance variations make it possible to find the exact shim thickness required.
Shim Thickness "S 1 ", Determining
Formula: "S 1 " = "S total " - "S 2 "
| Example: | ||
|---|---|---|
| Total shim thickness "S total " for "S 1 " + "S 2 " | 2.22 mm | |
| - | Shim thickness "S 2 " | 0.77 mm |
| = | Shim thickness "S 1 " | 1.45 mm |
-- Determine the shim according to the table. Refer to the Parts Information for the part number.

Tolerance variations make it possible to find the exact shim thickness required.
-- Remove the old shims "S 1 *" and "S 2 *" and install the newly determined shims. Refer to OVERVIEW - DIFFERENTIAL .
Measurement Check
-- Turn the differential five turns in both directions after installing the shims "S 1 " and "S 2 " so that the tapered roller bearings can settle.
-- Measure backlash on the circumference four times.
