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 differential’s bearing outer race. Also insert the
selected spacer between the output shaft bearing outer
race and the transaxle case.
(2) Set so that the threaded hole of the reverse idler gearshaft’s head is facing in the direction indicated in the
illustration.
NOTE
If 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 the
transaxle case.
Specified’ sealant: MITSUBISHI genuinePart No. MD997740 or equiva-
lentLJ
Caution
Squeeze out sealant from the tube uniformly with-
out excess or discontinuity.(4) Install the transaxle case onto the clutch housing.
(5) Insert a Phillips screwdriver
[8 mm (.32 in.) shaft
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 thebolt by fingers.
(7) Tighten the all transaxle tightening bolts to specified
torque.(8) Tighten the reverse idler gear shaft bolt to specified
torque.16.15. INSTALLATION OF LOCK NUTS
(1) Install the special tool to the splined end of input shaft.(2) Screw a bolt
[lo mm (.40 in.)] into the hole on the
periphery of clutch housing and attach a spinner handleto the special tool.
