b. Hoist engine and install it to the engine stand (commercial ser-
vice tool).
NOTE:
The figure shows an example of general-purpose engine stand
that can hold mating surface of transmission with drive plate and
rear plate removed.
5. Drain engine oil and engine coolant from inside engine. Refer toLU-6, "
Changing Engine Oil".
6. Drain engine coolant by removing drain plug from inside of
engine.
7. Remove the following parts and related parts. (Only major parts are listed.)
lIntake manifold (Refer toEM-20, "INTAKE MANIFOLD".)
lTurbocharger (Refer toEM-28, "TURBO CHARGER".)
lExhaust manifold (Refer toEM-34, "EXHAUST MANIFOLD".)
lRocker cover (Refer toEM-56, "ROCKER COVER".)
lFuel injector (Refer toEM-44, "INJECTION TUBE AND FUEL INJECTOR".)
lOil pan and oil strainer (Refer toEM-36, "OIL PAN AND OIL STRAINER".)
lWater pump (Refer toCO-21, "WATER PUMP".)
lThermostat and water piping (Refer toCO-23, "THERMOSTAT AND WATER PIPING".)
lSecondary timing chain (Refer toEM-73, "SECONDARY TIMING CHAIN".)
lPrimary timing chain (Refer toEM-79, "PRIMARY TIMING CHAIN".)
lFuel pump (Refer toEM-49, "FUEL PUMP".)
lVacuum pump (Refer toEM-42, "VACUUM PUMP".)
lCamshaft (Refer toEM-59, "CAMSHAFT".)
lCylinder head (Refer toEM-92, "CYLINDER HEAD".)
lOil cooler (Refer toLU-11, "OIL COOLER".)
lAccessory, accessory bracket and mount brackets
8. Remove fuel pump bracket.
9. Remove rear oil seal retainer.
lInsert a flat-bladed screwdriver between main bearing cap and rear oil seal retainer to remove retainer.
10. Remove rear oil seal from rear oil seal retainer. Refer toEM-70, "
OIL SEAL".

b. Using the industrial use dryer, heat pistons up to 60 to 70°C(140
to 158°F).
c. Using rod with outer diameter of 26 mm (1.02 in), press piston
pins out.
15. Remove main bearing cap bolts.
lWith a TORX socket (size: E14, commercial service tool),
loosen main bearing cap bolts in several stages in the reverse
order of that shown in the figure and remove them.
lBefore loosening main bearing cap bolts, measure crankshaft
end play. Refer toEM-124, "
CRANKSHAFT END PLAY".
16. Remove main bearing caps.
lUsing 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
andmainbearingcaps.
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)
lIf it exceeds the limit, replace connecting rod and/or piston and piston pin assembly. Refer toEM-122,
"HOW TO SELECT CONNECTING ROD BEARING"and/orEM-121, "HOW TO SELECT PISTON".
CYLINDER BLOCK TOP SURFACE DISTORTION
lUsing 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.
lUse straightedge and feeler gauge to check block upper surface
for six distortion.
lIf it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
lWithout installing main bearings, install main bearing caps, and
tighten bolts to the specified torque. Refer toEM-114, "
ASSEM-
BLY"EM-114, "ASSEMBLY".
lMeasure the inner diameter of main bearing housing with a bore
gauge.
lIf the measurement is out of the standard, replace cylinder block
andmainbearingcaps.
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)

lWhen installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
lUnladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
lAfter installing suspension components, check the wheel alignment.
lLock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.
