CAUTION)
Using a 4.5 mm diameter pin punch, drive the oil jet from the crankshaft
journal bearing bore side of the cylinder block until it bottoms.
)
Install the two thrust bearings in the No. 3 bearing bore in the cylinder block. Each
thrust bearing must be installed with the grooved end toward the crankshaft web.
NOTE: Applying engine oil to the bearings will help facilitate holding them in position.
)
- Location of crankshaft journal diameter marks.
<Bearing selection example>
If the crankshaft journal diameter mark is “0” and the cylinder block bearing bore mark is “1,” then select a bearing with a “2” mark as the No. 1, 2, 4 or 5 bearing and a bearing with a “1” mark as the No. 3 bearing.
If the crankshaft journal diameter mark is illegible, measure the journal diameter and select a bearing with the mark corresponding to the measurement.
)
- The diameter identification marks of the bearing bores in the cylinder block are stamped in the location shown in the drawing.

- The size mark of each crankshaft bearing is indicated by ink in the location shown in the drawing.
)
- Install bearing halves with oil grooves in the cylinder block bearing bores.
- Install bearing halves with no oil grooves in the beam bearing cap.
)
- Measure the shank length of each bearing cap bolt before installation. If the measurement exceeds the limit, replace the bolt.
Limit: 71.1 mm
- Apply engine oil to the threads and bearing surface of the bolt.
)
- Tighten the bolts to 25 ± 2 N·m in the indicated sequence.
- Make a paint mark on the head of the bolt.
- Make a paint mark on the bearing cap at a point 90 to 100° away from the paint mark made on the bolt head in the tightening direction.
)
- If the tightening angle is less than 90°, adequate tightness could not be assured.
- If the tightening angle exceeds 100°, loosen the bolt completely and then perform the tightening again beginning with the first step.
- Turn clockwise the bolts 90° to 100° in the indicated tightening sequence to bring the mark on each bolt head into alignment with that on the bearing cap.
CAUTION)
- After installing the beam bearing cap, measure the end play of the crankshaft. If the end play exceeds the limit, replace the crankshaft bearings.
Standard value: 0.05 -
0.25 mm
Limit: 0.4 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)
)
- 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:
- 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.
