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

10 mm (4in.) in length and 1.6 mm
(.06 in.) in diameter as
illustrated and install the outer races.
’(2) Install the transaxle case and tighten the bolts to
specified torque.
(3) Remove the transaxle case.
(4) Remove the outer races and remove the solder.
(5) If the solder is not broken, carry out the work- in steps
(l)-(4) with large diameter solder.
(6) Measure the thickness of the crushed soid& with a
micrometer and select and install a spacer of thickness
that gives standard preload and end play.

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
*
torque.,-(8) Tighten the reverse idler gear shaft bolt to specified

(1) Install the spacer on the back of the side gear and then
install the gear in the differential case.
Caution
When installing a new side gear, use a spacer ofmedium thickness [0.93-1.00 mm (.36-.04 in.)].
(2) Set the washer on the back of each pinion and insert thetwo pinions to specified position while engaging
them
with the side gears and turning them.
(3) Insert the pinion shaft.
(4) Measure the backlash between the side gears and
pinions.
Standard value:0.025-0.150 mm
LOO1 -.006 in.)
(5) If the backlash is out of specification, disassemble againand using correct spacer, reassemble and adjust.
Caution
Adjust for same backlash of both side gears.
4. INSTALLATION OF LOCK PINAlign the pinion shaft lock pin hole with the case lock pin
hole and insert the lock pin.
Caution1. Do not reuse the lock pin.
2. The lock pin head must be sunk from the flange
surface of the differential case.
