If necessary, take the measurements in steps 9 to 18 after 
replacing the pressure plate, brake plate and brake disc.
20.Remove all parts and special tools that were installed to 

take the measurements in steps 9 to 18. Remove and 
separate the pressure plate and snap ring chosen in steps 
12, 16 and 18.

21.Install the snap ring into the groove of transaxle case output

output shaft bearing outer race in the transaxle case.

CAUTION

Do not reuse the bolt, as it has had sealant applied.
23.Tighten the mounting bolts of the output shaft bearing 

retainer to the specified torque.

Tightening torque:

specified torque again.

Tightening torque: 170 

± 10 N⋅m (125 ± 7 ft-lb)

NOTE: The jam nut is reverse threaded.

26.Move the output shaft to measure the end play and record
