REMOVAL SERVICE POINTS

<<A>> DRIVE PLATE / FLYWHEEL REMOVAL

1.Using the special tool Flywheel stopper (MD998781), hold the drive plate or flywheel in place.
2.Remove the drive plate bolts or flywheel bolts.

INSTALLATION SERVICE POINTS

>>A<< DETONATION SENSOR BRACKET INSTALLATION

Check that the bracket is in proper contact with the cylinder block boss and tighten to the specified torque of 28 ± 2 N·m in the order shown.

>>B<< CRANKSHAFT BEARING INSTALLATION

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 colors/marks of its journals are painted/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.

Shaft and bore combination					Bearing
Crankshaft			Cylinder block bearing bore diameter
Outside diameter of shaft mm	Identification mark		Identification mark		Identification mark
	Classification	Mark	Classification	Mark
59.994 - 60.000	0	0	a	I	1
			b	II	2
			c	III	3
59.988 - 59.994	I	1	a	I	2
			b	II	3
			c	III	4
59.982 - 59.988	II	2	a	I	3
			b	II	4
			c	III	5

3.If the measured value of a crankshaft journal outer diameter is 59.996 mm, the journal is classified as "0" in the table.
In case the crankshaft is also replaced by a spare part, check the identification mark of the journals painted on the new crankshaft.
If the mark is "0", for example, the journal Classification is classified as "1".
Next check the cylinder block bearing bore identification mark stamped on the cylinder block. If it is "I", read the "Bearing identification mark" column to find the identification mark of the bearing to be used.
In this case, bearing is "1

4.Install bearings with a groove to the cylinder block.
5.Install the bearings having no groove to the bearing cap.

>>C<< CRANKSHAFT THRUST BEARING INSTALLATION

1.Install the thrust bearing in the No.3 bearing bore in the cylinder block and in the bearing cap. 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 groove toward the crankshaft web.

>>D<< BEARING CAP / BEARING BOLT INSTALLATION

1.Attach the bearing cap on the cylinder block as shown in the illustration.

2.Tighten the bearing cap bolts to specified torque of 93 ± 4 N·m in the sequence shown in the illustration.

3.Check that the crankshaft rotates smoothly.

4.Check the end play. If it exceeds the limit value, replace the thrust bearing.
Standard value: 0.05 - 0.25 mm
Limit: 0.3 mm

>>E<< CRANKSHAFT REAR OIL SEAL INSTALLATION

Using special tool Crankshaft rear oil seal installer (MD998718), press-fit a new crankshaft rear oil seal into the oil seal case.

>>F<< OIL SEAL CASE INSTALLATION

1.Remove completely old FIPG remaining on the rear oil seal case and cylinder block.

2.Apply the sealant to the oil seal case.
Specified sealant:
Mitsubishi Genuine Part No.MD970389 or equivalent
3.Apply a small amount of engine oil to the entire circumference of the oil seal lip section, and place the oil seal case on the cylinder block.

note

Install the oil seal case within 15 minutes after applying liquid gasket.

note

Then wait at least one hour. Never start the engine or let engine oil or coolant touch the adhesion surface during that time.

>>G<< DRIVE PLATE BOLT / FLYWHEEL BOLT INSTALLATION

1.Using the special tool Flywheel stopper (MD998781) secure the drive plate or flywheel.
2.Tighten the drive plate bolt or flywheel bolt to the specified torque.
Flywheel bolt : 73.5 ± 2.0 N·m.
Driveplate bolt : 74 ± 2 N·m.
