• MD998776: Crankshaft Rear Oil Seal Installer

INSTALLATION SERVICE POINTS

.

>>A<< BLOCK HEATER INSTALLATION
Within 30

° of the center, install the block heater as shown in

Fig.

.

>>B<< 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 grooved side

facing toward the crankshaft web.

.

>>C<< 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 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 identifi-
cation 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.

>>D<< 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: 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 the specified torque in the tightening

sequence shown.

Tightening torque: 25

± 2N⋅m (18 ± 1 ft-lb)

5. Make a paint mark on the head of each 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 degrees, proper fasten-

ing performance may not be achieved. Be sure to turn
the bolt exactly 90 degrees.

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.

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 mm (0.002 − 0.009 inch)

Limit: 0.40 mm (0.015 inch)

>>E<< OIL SEAL INSTALLATION
Using special tools MD998776 and MB990938, press-fit the oil
seal in the case.

.

>>F<< 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.

4. Install the crankshaft bearing cap carefully and tighten the

bolts to the specified torque.

5. Carefully remove the crankshaft bearing cap.
