Mount Tooling (L) onto the housing, as shown. Measure the backlash between the pinion and the bevel gear. The proper backlash setting is 0.15 to 0.25 mm (0.006 to 0.010 inch).
If the backlash is less than the specified amount, decrease the thickness of the shim on the side of the bevel gear and increase the thickness of the shim on the opposite side by the same amount. If the backlash is greater than the specified amount, increase the thickness of the shim on side of the bevel gear and decrease the thickness of the shim on the opposite side by the same amount.

Use a dial type torque wrench and measure the total rotating torque. Use the following formula in order to calculate the total rotating torque (TRT): P equals the rotating torque that was measured in Step 17. TRT = P + 0.297 N m (2.63 lb in) to P + 0.444 N m (3.93 lb in).
If the total rotating torque (TRT) is less than the specified amount, increase the thickness of the shim on both sides by the same amount. If the total rotating torque (TRT) is greater than the specified amount, decrease the thickness of the shim on both sides by the same amount.
