CAUTION

Use care to install the thrust bearing in the proper direc-
tion.
45.Attach thrust bearing number 6 to the inside of the overdrive 

clutch hub using petroleum jelly (Vaseline). Then install the 
assembly in the reverse and overdrive clutch.

46.Install the reverse and overdrive clutch.

CAUTION

Be sure to install the thrust bearing in the correct direction 
as shown.
47.Check the installation direction of thrust bearing number 7, 

and install it on the reverse clutch retainer.

48.Use special tool MB990938 to tap the input shaft rear 

bearing in the rear cover.

49.Install the four seal rings in the grooves of the rear cover.

50.Measure the end play of the under drive sun gear by the 

following procedures:

(1) Install the thinnest thrust race number 8 [thickness 1.6 

mm (0.063 inch); part number MD707267] on thrust 
bearing number 7.

(2) Install the rear cover on the transaxle case and tighten 

the bolts to the specified torque.

Tightening torque: 23 

± 3 N⋅m (17 ± 2 ft-lb)

(3) Turn over the transaxle case so that the installation 

surface of the torque converter housing is facing up.

(4) Install the under drive clutch hub on the under drive sun 

gear.

(5) Measure end play of the underdrive sun gear and record 

the measurement value.

Standard value (Reference):
0.25 

− 0.45 mm (0.0098 − 0.0177 inch)

(6) After taking the measurement in steps (5), take out the 

installed parts in steps (1) through (4).

51.Install the three O-rings.

52.Select a thrust race number 8 whose thickness corresponds 

to the measured values taken in step 50 from the table 
below. Install it on thrust bearing number 7.

53.Apply a 2 mm (0.08 inch) diameter bead of sealant 

(MITSUBISHI Genuine Part number MD974421 or 
equivalent) to the illustrated position of the rear cover.
NOTE: Be sure to install the case quickly while the sealant is 
wet (within 15 minutes) or leaks will occur if the rear cover is 
installed after the sealant dries.
