1.Install the two thrust
bearings in the number 3 bearing bore in the cylinder block.
For easier installation, apply engine oil to the bearings;
this will help hold them in position.
|
|
2.The thrust bearings must
be installed with their groove side toward the crankshaft
web.
|
|
|
When bearing replacement is
required, select and install the correct bearing by the
following
procedure.
|
|
1.Measure the crankshaft
journal diameter and confirm its classification from the
following
table. In the case of a crankshaft supplied as a service
part, identification marks of its journals
are stamped at the positions shown in the
illustration.
|
|
2.The cylinder block bearing
bore diameter identification marks are stamped at the
position
shown in the illustration from left to right, beginning at
No.1.

For example, if the crankshaft
journal outside diameter identification mark is "0" and
cylinder block bearing bore identification mark is "1,"
select a bearing whose identification mark
is "2" for number 1, 2, 4 and 5, and a bearing whose
identification mark is "1" for number 3.
If there is no
identification mark on the crankshaft, measure the journal
outside diameter
and select a bearing appropriate for the measured
value.
|
|
3.Install the bearings
having an oil groove to the cylinder
block.
4.Install the bearings having no oil groove
to the bearing cap.
|
|
|
1.Install the bearing caps
so that the arrow points to the timing belt side.
|
|
2.Before installing the
bearing cap bolts, check that the shank length of each bolt
meets
the limit. If it exceeds the limit, replace the
bolt.
Limit: 71.1 mm
3.Apply
engine oil to the threaded portion and bearing surface of
the bolt.
|
|
4.Tighten the bolts to the
specified in the tightening sequence
shown.
Tightening torque: 25 ± 2
N·m
|
|
5.Make a paint mark on the
head of each bolt.
6.Make a paint mark on the
bearing cap 90 degrees from the paint mark made on the bolt
in the direction of tightening the bolt.
| caution |
- If the bolt is overtightened,
loosen the bolt completely and then
retighten it by repeating the tightening
procedure from
step 4.
- If the bolt is turned less than 90
degrees, proper fastening performance
may not
be achieved. Be sure to turn the bolt
exactly 90 degrees.
|
7.Turn each bolt 90 degrees in the tightening
sequence specified in step 4, and make
sure that the paint marks on the bolt and cap are
aligned.
|
|
8.Make sure that the
crankshaft turns smoothly and the end play is correct. If
the end play
exceeds the limit, replace the number 3 crankshaft
bearings.
Standard value: 0.05 - 0.25

Limit: 0.40 mm

Use the special tools to press-fit
the rear oil seal in the rear oil seal
case.
- Handle (MB990938)
- Crankshaft rear oil seal installer
(MD998776)
|
|
|
1.Remove completely old FIPG
remaining on the rear oil seal case and cylinder
block.
|
|
2.Apply a bead of FIPG to
the surface of the rear oil seal case as shown in the
drawing.
Specified
sealant:
Mitsubishi Genuine Part
No.MD970389 or equivalent
| note |
Be sure to install the case
quickly while the sealant is wet (within 15
minutes).
|
3.Install the oil seal into the cylinder
block after applying an appropriate amount
of engine oil to the entire circumference of its lip
portion.
4.Install the rear oil seal case by
tightening its bolts to 11 ± 1 N·m.
| note |
After installation, keep the
sealed area away from the oil for approximately
one hour.
