CYLINDER BLOCK


Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding
oil holes.

Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the speci-
fied torque. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod cap and bearing, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and lower cylinder block, and tighten lower cylinder block mounting
bolts to the specified torque. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.

(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)

If the clearance exceeds the limit, select proper main bearing
according to main bearing housing inner diameter and crankshaft main journal diameter to obtain speci-
fied bearing oil clearance. Refer to EM-95, "
HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding

bolts to the specified torque. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove lower cylinder block and bearings, and using the scale
on the plastigage bag, measure the plastigage width.

PRECAUTIONS


When tightening bolts and nuts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

Replace with new gasket, packing, oil seal or O-ring.

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

Release air within route when refilling after draining engine coolant.

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Parts Requiring Angle TighteningBBS007TV

Use angle wrench [SST: KV10112100] for the final tightening of the following engine parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap nuts (VQ23DE)
–Connecting rod cap bolts (VQ35DE)
–Crankshaft pulley bolt

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid GasketBBS007TW
REMOVAL OF LIQUID GASKET SEALING

After removing mounting nuts and bolts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the gasket
application surface and the mating surface.

Remove liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

TIMING CHAIN

b. Remove camshaft sprockets (INT and EXH) mounting bolts.

Secure the hexagonal portion of camshaft using wrench to
loosen mounting bolts.
CAUTION:
Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
c. Remove timing chain (secondary) together with camshaft sprockets.

Turn camshaft slightly to secure slackness of timing chain on timing chain tensioner (secondary) side.

Insert 0.5 mm (0.020 in)-thick metal or resin plate between
timing chain and timing chain tensioner plunger (guide).
Remove timing chain (secondary) together with camshaft
sprockets with timing chain loose from guide groove.
CAUTION:
Be careful of plunger coming-off when removing timing
chain (secondary). This is because plunger of timing
chain tensioner (secondary) moves during operation,
leading to coming-off of fixed stopper pin.
NOTE:
Camshaft sprocket (INT) is two-for-one structure of sprockets
for timing chain (primary) and for timing chain (secondary).

When handling camshaft sprocket (INT), be careful of the fol-
lowing caution:
CAUTION:

Handle carefully to avoid any shock to camshaft
sprocket.

Do not disassemble. (Do not loosen bolts “A” as
shown in the figure).
22. Remove water pump. Refer to CO-46, "
WATER PUMP" .
23. Remove rear timing chain case as follows:
a. Loosen and remove mounting bolts in the reverse order as
shown in the figure.
b . C u t l i q u i d g a s k e t u s i n g s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ] a n d
