Put the straight edge on the mating surface of the transaxle case assembly and measure the dimension "B" with a vernier caliper.
Select the shim whose dimension is the difference between "B" and "A."
Install the output shaft assembly and differential assembly to the clutch housing case assembly. Tighten the transaxle case bolts to the specified torque.
Tightening torque: 29.0 ± 5.8 N.m (21 ± 3 ft-lb)
