c. Using rod with outer diameter of 26 mm (1.02 in), press piston
pins out.
15. Remove main bearing cap bolts.

With a TORX socket (size: E14, Commercial Service Tool),
loosen main bearing cap bolts in several stages in reverse
order of that shown in the figure and remove them.

Before loosening main bearing cap bolts, measure crankshaft
end play. Refer to EM-245, "
CRANKSHAFT END PLAY" .
16. Remove main bearing caps.

Using main bearing cap bolts, remove by rocking bearing cap
back and forth.
17. Remove crankshaft.
18. Remove main bearings and thrust bearings from cylinder block and main bearing caps.
CAUTION:
Check the correct installation locations of removed parts. Store them so they do not get mixed up.
19. Remove oil jet.
20. Remove oil jet relief valve.
ASSEMBLY
1. Blow air sufficiently to inside engine coolant passage, engine oil passage, crankcase and cylinder bore to
remove foreign matter.
CAUTION:
Use a goggles to protect your eye.

Piston Pin Outer Diameter
Use micrometer to measure piston pin outer diameter.
Calculation of Connecting Rod Bushing Clearance
(Connecting rod bushing clearance) = (Connecting rod bushing inner diameter) − (Piston pin outer diameter)

If it exceeds the limit, replace connecting rod and/or piston and piston pin assembly. Refer to EM-242,
"HOW TO SELECT CONNECTING ROD BEARING" and/or EM-242, "HOW TO SELECT PISTON" .
CYLINDER BLOCK TOP SURFACE DISTORTION

Using scraper, remove gasket installed onto cylinder block sur-
face. Remove contamination such as engine oil, scale, and car-
bon.
CAUTION:
Keep broken pieces of gasket clear of engine oil and engine
coolant passages.

Use straightedge and feeler gauge to check block upper surface
for six distortion.

If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Without installing main bearings, install main bearing caps, and
tighten bolts to the specified torque. Refer to EM-235, "
ASSEM-
BLY" .

Measure the inner diameter of main bearing housing with a bore
gauge.

If the measurement is out of the standard, replace cylinder block
and main bearing caps.
NOTE:
These components cannot be replaced as a single unit, because
they were processed together.Standard : 27.995 - 28.000 mm (1.1022 - 1.1024 in)

Precautions for Liquid GasketEBS011UN
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.

Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts or nuts after the installation.

Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Intake valve timing control cover and intake valve timing control solenoid valve

Front cover

Mating surface between cylinder block and lower cylinder block

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Engine oil pressure check should be in “ Parking position” (A/T models) or “Neutral position” (M/T
models), and should apply parking brake securely.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove RH undercover.

Removal and InstallationEBS00KO8
WARNING:
Be careful not to get burned when engine and engine oil may be hot.
CAUTION:

When removing oil cooler and oil cooler bracket, prepare a shop cloth to absorb any engine oil
leakage or spillage.

Completely wipe off any engine oil that adhere to engine and vehicle.
REMOVAL
1. Remove RH front road wheel and tyre and RH undercover.
2. Drain engine coolant by removing water drain plug on cylinder block and radiator drain plug. Refer to EM-
89, "CYLINDER BLOCK" and CO-9, "Changing Engine Coolant" .
3. Disconnect water hoses from oil cooler.
4. Remove oil cooler and oil cooler bracket.
NOTE:
For reference when installing, put a mating mark on oil cooler and oil cooler bracket.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Relief Valve
Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and adjust engine oil and engine coolant. Refer to
LU-7, "
ENGINE OIL" and CO-9, "ENGINE COOLANT" .
