2. Each thrust bearing must be installed with the grooved side toward the crankshaft web.

1. 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.

2. The diameter identification marks of the bearing bores in the cylinder block are stamped in the location shown in the drawing.

3. The size mark of each crankshaft bearing is indicated by ink in the location shown in the drawing.

4. Install bearing halves with oil grooves in the cylinder block bearing bores.

5. Install bearing halves with no oil grooves in the beam bearing cap.

2. Measure the nominal length (shank length) of each bearing cap bolt before installation. If the measurement exceeds the limit, replace the bolt.
Limit: 71.1 mm

3. Apply engine oil to the threads and bearing surface of the bolt.

4. Tighten the bolts to 25 ± 2 N·m in the indicated sequence.

5. Make a paint mark on the head of each bolt.

6. Make a paint mark on the bearing cap at a point 90° to 100° away in the tightening direction from the paint mark made on the bolt head.

 CAUTION
• 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 procedure again beginning with the first step.
7. 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.

8. After installing the bearing caps, 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: 0.40 mm

Use the special tools to install the rear oil seal.

• Handle (MB990938)

• Crankshaft rear oil seal installer (MD998776)

1. Apply a bead of FIPG to the surface of the rear oil seal case as shown in the drawing.
Specified sealant:
• Mitsubishi Genuine Part No.MD970389 or equivalent

2. Install the oil seal into the cylinder block after applying an appropriate amount of engine oil to the entire circumference of its lip portion.
