3. Select the bearing from the above table according to
the identification confirmed in steps 1 and 2.
[Example of selecting bearing]
(1) If the measured outer diameter of the crankshaft
journal is 57.000 mm, Class 1 applies, and the
identification colour is yellow.
(2) If the cylinder block bearing bore identification mark
is 0, select identification mark 0 in consideration of
step (1).
4. Install the grooved bearing on the cylinder block side.
5. Install the bearing with no oil groove onto the beam bearing
cap side.
"CABEAM BEARING CAP/BEARING CAP BOLT
INSTALLATION
1. Install the beam bearing cap with the arrow facing the
timing belt side.
2. Before installing the bearing cap bolt, confirm that the
bolt’s underhead length is less than the limit value.
Replace the bolt if it exceeds the limit value.
Limit value: 71.1 mm
3. Apply engine oil on the bolt threads and bolt surface.
4. Following the tightening order, tighten the bearing cap
bolt at 25±2N•m.
5. Make paint marks on the bolt head.
6. Using the position of the mark painted on the bolt head
as reference, make paint marks on the seat surface at
the 90_to 100_positions in the tightening direction.
7. Following the tightening order, tighten the bolt by 90_
to 100_, and confirm that the paint marks made on the
bolt and seat surface match.
Caution
(1) If the tightening angle is less than 90_, the
connection performance may not be attained, so
take special care when tightening.
(2) If the tightening angle exceeds 100_, completely
loosen the nut, and start again from step 1.Crankshaft bearing side

8. After installing the beam bearing cap, inspect the end
play of the crankshaft. If the end play exceeds the limit
value, replace the crankshaft bearing.
Standard value: 0.05 - 0.25 mm
Limit value: 0.4 mm
"DAREAR OIL SEAL INSTALLATION
Press in the rear oil seal using the special tool.
"EAREAR OIL SEAL CASE INSTALLATION
1. Apply form-in-place gasket onto the rear oil seal case
at the position shown in the illustration.
Form-in-place gasket
Specified gasket:
Mitsubishi Genuine Part No. MD970389 or
equivalent
Caution
Evenly squeeze out the form-in-place gasket so that
it is not insufficient or excessive.
2. Apply an appropriate amount of engine oil on the entire
periphery of the oil seal lip, and install on the cylinder
block.

INSPECTION
1. CRANKSHAFT OIL CLEARANCE (PLASTIC GAUGE
METHOD)
The oil clearance can be measured easily by using the
“plastic gauge”.
Use the following steps to use the “plastic gauge”.
(1) Wipe off all oil from the crankshaft’s outer diameter
and bearing’s inner diameter.
(2) Assemble the crankshaft.
(3) Set a plastic gauge as long as the bearing width
on the journal shaft so that straightly aligned with
the shaft centre.
(4) Carefully install the beam bearing cap, and tighten
the bolt at the specified torque 25±2N•m+90_
to 100_.
(5) Remove the bolt, and carefully remove the beam
bearing cap.
(6) Measure the width of the crushed plastic gauge (at
the section crushed the most) with the scale printed
on the plastic gauge bag.
Standard value: 0.03 - 0.04 mm
Limit value: 0.1 mm
2. CYLINDER BLOCK
(1) Visually check for the presence of scratches, rusting,
or corrosion, and using flaw detection agent, etc.,
check for cracks. If any faults are found, repair or
replace the part.
(2) Using a straight edge and thickness gauge, measure
the flatness of the cylinder block’s upper surface.
Make sure that no gasket pieces, etc., are adhered
to the upper surface of the cylinder block when
measuring.
Standard value: 0.05 mm
Limit value: 0.1 mm
(3) Check for the presence of scratches or seizure on
the cylinder wall. If any faults are found, repair (over
size) or replace the part.
(4) Using a cylinder gauge, measure the inner diameter
and cylindricity of the cylinder. If greatly worn, repair
the cylinder to the over size, and replace the piston
ring.
Standard value: 85.0 mm
Cylindricity: 0.01 mm
Plastic gauge
12 mm

3. CYLINDER BORING
(1) Select the oversized piston to be used using the
maximum inner diameter cylinder as a reference.
(2) There are two types of oversized pistons (0.50 mm,
1.00 mm), so bore so that the clearance is at the
specified value that matches the piston’s outer
diameter. The reference points for measuring the
piston’s outer diameter are shown in the illustration.
(3) Calculate the boring finish dimensions based on the
piston outer diameter measurement value.
Boring finish dimension = Piston outer diameter +
0.02 to 0.04 mm (clearance with cylinder) - 0.02 mm
(honing margin)
(4) Bore each cylinder to the boring finish dimensions
calculated above.
Caution
To prevent strain caused by a temperature rise
during boring, bore in the order of the No. 2→
No. 4→No. 1→No. 3 cylinders.
(5) Hone to the final finish dimension (piston outer
diameter + clearance with cylinder).
(6) Confirm the clearance between the piston and
cylinder.
Standard value: 0.02 - 0.04 mm
Piston outer diameter 11.65 mm

ENGINE LUBRICATION -General Information12-2
GENERAL INFORMATION
The lubrication method is a fully force-fed, full-flow
filtration type. The oil pump is a gear type which
is driven by the crankshaft via the timing belt.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis.
In addition, used engine oil contains potentiallyharmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious
gloves where practicable.
DAvoid contaminating clothes, particularly
underpants, with oil.
DDo not put oily rags in pockets, the use of
overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and
oil - impregnated foot - wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.DWhere there is a risk of eye contact, eye
protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
DObtain First Aid treatment immediately for open
cuts and wounds.
DWash regularly with soap and water to ensure
all oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas
oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
DIf skin disorders develop, obtain medical advice
without delay.
