47./48. INSTALLATION OF SHIFT RAILS AND FORKS(1) Set the
lst-2nd speed shift sleeve at 2nd Speed.
(2) Set the
3rd-4th speed shift sleeve at 4th spe$d.(3) Fit the shift forks of shift rail assembly to groove of
sleeves.(4) Insert the shift rails into the shift rail holes of clutch
housing.(5) Turn the shift rails in the directions indicated by the
arrows in the order shown in the illustration, and
engage the shift lugs to control finger and interlock
plate.
45.146. INSTALLATION OF SPRING PINS
Install the spring pins using the special tool or a pin Punch.When installing, make sure that the slit of the spring pin is
aligned with the shift rail center line.
Caution
Do not reuse the spring pins.
35.137.139. SELECTION OF SPACERS
(1) Place two pieces of solder measuring about Ia mm (.4in.) in length and 1.6 mm
(.06 in.) in diameter as
illustrated and install the outer races of intermediate
gear and differential.
(2) With a solder puddle measuring
10 mm (.39 in.) long
and 1.6 mm (.06 in.) across on the transaxle case at thelocation shown in the figure, install the
bearing outer
race of the shaft.
(3) Install the transaxle case and tighten the bolts to
specified torque.
(4) Remove the transaxle case.
(5) Remove the outer races and take out the crushed
solder.(6) If the solder is not broken, carry out the work in steps
(l)-(5) with large diameter solder.

Output shaft0.05-0.10 mm (.002-.004 in.)
Differential case0.05-0.10 mm (.002-,004 in.)
33. INSTALLATION OF OIL SEALInstall the drive shaft oil seal using the special tool.
27. INSTALLATION OF OIL GUIDEInstall the oil guide to the transaxle case as illustrated.
26. INSTALLATION OF TRANSAXLE CASE(1) Place the selected spacers on the intermediate gear
and the differential’s bearing outer race. Also insert the
selected spacer between the output shaft bearing outerrace and the transaxle case.
(2) Set so that the threaded hole of the reverse idler gear
shaft’s head is facing in the direction indicated in the
illustration.
NOTEIf there is a great deviation in the direction in which the
threaded hole is facing, it will be impossible to align thethreaded hole and the hole in the case after the
transaxle case is installed.
(3) Apply specified sealant to the clutch housing side of thetransaxle case.
Specified sealant: MITSUBISHI GenuinePart
No.MD997740 or
equivalent
CautionB
Squeeze out sealant from the tube uniformly with- -
out excess or discontinuity.(4) Install the transaxle case onto the clutch housing.

diameter] into the bolt hole in the case, as shown in thefigure, and use it to align the threaded hole of the
reverse idler gear shaft with the bolt
hole in the
transaxle case.
(6) Install the reverse idler gear shaft bolt and tighten the
bolt by fingers.
(7) Tighten the all transaxle tightening bolts to specified
(8)
E$r& the reverse idle gear shaft bolt to specified
torque.
15./ 16. INSTALLATION OF LOCK NUTS(1) Install the special tool to the splined end of input shaft.
(2) Screw a bolt
(10 mm) into the hole on the periphery of
clutch housing and attach a spinner handle to the
special tool.
(3) Shift the transmission in reverse using control lever andselect lever.
(4) Tighten the lock
nut,to specified torque, while ‘using the
bolt attached in the above step as a spinner handle
stopper.(5) Loosen the lock nuts.
(6) Retighten the lock nuts to the specified torque.
(7) Stake the lock nut.
14. INSTALLATION OF SPRING PIN(1) Install the spring pin using the special tool or a pin
punch.
Caution
Do not reuse the spring pins.
