- The thrust bearings must be installed with their groove side toward the crankshaft web.
)
- 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.
)
- 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.
If there is no identification mark on the crankshaft, measure the journal outside diameter and select a bearing appropriate for the measured value.
)
- Install the bearings having an oil groove to the cylinder block.
- Install the bearings having no oil groove to the bearing cap.
)
- 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
- Apply engine oil to the threaded portion and bearing surface of the bolt.
)
- Tighten the bolts to the specified in the tightening sequence shown.
Tightening torque: 25 ±
2 N·m
)
- Make a paint mark on the head of each bolt.
- 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.
- 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.
)
- 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.

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)
)
- Apply a bead of FIPG to the surface of the rear oil seal case as shown in the drawing.
- Mitsubishi Genuine Part No.MD970389 or equivalent
Specified sealant:
NOTE: Be sure to install the case quickly while the sealant is wet (within 15 minutes).
- Install the oil seal into the cylinder block after applying an appropriate amount of engine oil to the entire circumference of its lip portion.
- 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.
