>>D<<BEARING CAP/BEARING CAP BOLT INSTALLATION
1. Install the bearing cap on the cylinder block, so that the
arrow points to the timing belt side.
2. Tighten the bearing cap bolts to 93 N
⋅
m (69 ft-lb) in the
specified tightening sequence.
3. Check that the crankshaft rotates smoothly.
4. Check the end play. If it exceeds the limit value, replace the
thrust bearing.

>>F<< OIL SEAL CASE ASSEMBLY INSTALLATION
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 lip of the oil seal, 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 plastic gauging material to the same length as the width
of the bearing and place it on the 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.
Standard value: 0.02

0.04 mm (0.0008

0.0015 inch)
Limit: 0.1 mm (0.003 inch)
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 (0.002 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 (0.008 inch)
*Includes/combined with cylinder head grinding.

Cylinder block height (when new):
210.5 mm (8.29 inches)
4. Check the 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 by boring the cylinders to
an oversize and replace pistons and piston rings. Measure
at the points shown in the illustration.
Standard value:
Cylinder Inside Diameter: 91.1 mm (3.59 inches)
Cylindricity: 0.01 mm (0.0003 inch)
BORING CYLINDER
1. Oversize pistons to be used should be determined on the
basis of the largest bore cylinder.
Piston size identification
NOTE: Size mark is stamped on the piston top.
2. Measure the outside diameter of the piston to be used.
Measure it in the thrust direction as shown.
3. Based on the measured piston Outside Diameter (OD),
calculate the boring finish dimension.
Boring finish dimension =
Piston OD + (clearance between piston OD and
cylinder)
−−−−
0.02 mm (0.0008 inch) (honing margin)
CAUTION
To prevent distortion that may result from temperature rise
during honing, bore cylinders in the order of number 2,
number 4, number 6, number 1, number 3 and number 5.
4. Bore all cylinders to the calculated boring finish dimension.
5. Hone to the final finish dimension (piston OD + clearance
between piston OD and cylinder).
6. Check the clearance between the piston and cylinder.
Clearance between piston and cylinder:
0.02
−−−−
0.04 mm (0.0008 -.0015 inch)
NOTE: When boring cylinders, finish all of six cylinders to
the same oversize. Do not bore only one cylinder to an
oversize.
