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 ID color
is "Yellow" and cylinder block bearing bore ID mark is "1,"
select a bearing whose ID mark is "2" or ID color is "Yellow" for
number 1, 2, 4 and 5, and a bearing whose ID mark is "1" or ID
color is "Green" for number 3.
If there is no ID color paint 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.

>>C<< 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 (A): 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 25 N

⋅

m (18 ft-lb) in the tightening

sequence shown.

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

6. Make a paint mark on the bearing cap at the position 90

degree angle 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 degree angle, proper
fastening performance may not be achieved. Be sure to
turn the bolt exactly 90 degree angle.

7. Turn each bolt 90 degree angle in the tightening sequence

specified in step 4, and make sure that the paint marks on
the bolt and cap are aligned.

play is correct. If the end play exceeds the limit, replace the
number 3 crankshaft bearings.

>>D<< OIL SEAL INSTALLATION
Using special tools MD998776 and MB990938, press-fit the oil
seal in the case.

>>E<< 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.

6. Measure the width of the plastic gauging material at its

widest part by using a scale printed on the plastic gauging
material package.

CYLINDER BLOCK
1. Visually check for scratches, rust, and corrosion.

Use also a flaw detecting agent for the check. If defects are
evident, correct or replace.

2. Using a straightedge and feeler gauge, check the block top

surface for warpage. Make sure that the surface is free from
gasket chips and other foreign matter.

Standard value: 0.05 mm (0.0020 inch)
Limit: 0.1 mm (0.003 inch)

3. If the distortion is excessive, correct within the allowable

limit or replace.

Grinding limit: 0.2 mm (0.007 inch)
*Includes/combined with cylinder head grinding
Cylinder block height (when new)
:290 mm (11.4 inches)

4. Check cylinder walls for scratches and seizure. If defects

are evident, replace or bore to oversize and replace pistons
and piston rings.

5. Using a cylinder gauge, measure the cylinder bore and

cylindricity. If worn badly, correct the cylinder to an oversize
and replace the piston and piston rings. Measure at the
points shown in the illustration.

Standard value:

Cylinder inner diameter 86.50 mm (3.406 inches)
Cylindricity 0.01 mm (0.0003 inch) or less
