CRANKSHAFT AND CYLINDER BLOCK

TSB Revision

ENGINE OVERHAUL <2.4L ENGINE>

11B-61

Required Special Tools:

• MB990938: Handle

• 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)

>>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.
