• MD998776: Crankshaft Rear Oil Seal Installer

INSTALLATION SERVICE POINTS

.

>>A<< CRANKSHAFT THRUST BEARING INSTALLATION
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.

.

>>B<< CRANKSHAFT BEARING INSTALLATION
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
colors/marks of its journals are painted/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 identifi-
cation mark is "0" or identification color is "Yellow" and cylinder
block bearing bore identification mark is "1," select a bearing
whose identification mark is "2" or identification color is "Yellow"
for number 1, 2, 4 and 5, and a bearing whose identification
mark is "1" or identification color is "Green" for number 3.
If there is no identification color paint or 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.

.

>>C<< BEARING CAP/BEARING CAP BOLT INSTALLATION
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 (A): 71.1 mm (2.79 inches)

3. Apply engine oil to the threaded portion and bearing surface

of the bolt.

4. Tighten the bolts to 25

± 2 N⋅m (18 ± 1 ft-lb) in the tightening

sequence shown.

5. Make a paint mark on the head of each bolt.
6. Make a paint mark on the bearing cap at the position 90

degree angle 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 proce-
dure from step 4.

• If the bolt is turned less than 90 degree angle, proper

fastening performance may not be achieved. Be sure to
turn the bolt exactly 90 degree angle.

7. Turn each bolt 90 degree angle in the tightening sequence

specified in step 4, and make sure that the paint marks on
the bolt and cap are aligned.

seal in the case.

.

>>E<< SEALANT APPLICATION TO OIL SEAL CASE
1. Apply sealant MITSUBISHI Genuine Part number

MD970389 or equivalent to the gasket surface of oil seal
case.
NOTE: Be sure to install the case quickly while the sealant is
wet (within 15 minutes).

2. Apply engine oil to the oil seal lip, and then install the oil seal

case onto the cylinder block.
NOTE: After installation, keep the sealed area away from
the oil for approximately one hour.

CRANKSHAFT JOURNAL OIL CLEARANCE
<PLASTIC GAUGING MATERIAL METHOD>
1. Remove oil from the crankshaft journal and crankshaft

bearing.

2. Install the crankshaft.
3. Cut the plastic gauging material to the same length as the

width of bearing and place it on journal in parallel with its
axis.
