For performing procedure “6”, adjustment of chain guide.
3. Install rear camshaft sprocket.
4. Fit drive chain onto rear camshaft sprocket and vacuum pump
sprocket.
5. Install (insert) SST to rear camshaft sprocket from the rear via
cylinder head rear cover.

PRIMARY TIMING CHAIN

a. Apply a continuous bead of liquid gasket with the tube presser
(special service tool: WS39930000) on locations shown in the
figure.
Use Genuine Liquid Gasket or equivalent.
b. Install four O-rings to the grooves of the cylinder block and fuel
pump bracket.
c. Install rear chain case.

When installing, align the dowel pin with the pin hole.A : Apply bead so that it does not protrude into the
oil passage.
B. C : Minimize overlapping area of bead, by starting
and ending at areas of bead as shown in the fig-
ure. Apply so that the portion marked.
D : Leave the start and end areas of the bead slightly
protruding from the case surface.
* : comes at an external location but cannot be
viewed externally after engine assembly.

a. Apply a continuous bead of liquid gasket with the tube presser
(special service tool: WS39930000) as shown in the figure.
b. Install oil pump drive spacer to crankshaft.

Install with the front mark (punched mark) facing the front of
the engine.
c. Install O-ring into the groove of rear chain case.
d. Install oil pump housing.

When installing, align the inner rotor in the direction of the two facing flats of oil pump drive spacer.

When installing, align the dowel pin with the pin hole.
e. Tighten fixing bolts in numerical order shown in the figure.
f. After tightening all the bolts, re-tighten in the same order.
14. Check gaps on upper oil pan mounting surface.

Using straightedge and feeler gauge, measure gaps between
the locations of the following parts:

If the measured value is out of the standard, install again.
15. Install crankshaft pulley as follows:
a. Install crankshaft pulley, taking care not to damage front oil seal.
CAUTION:
Do not tap pulley on the side surface where belt is installed (outer circumference).A : Leave the start and end areas of the bead slightly
protruding from the surface.
B : Apply liquid gasket along upper end surface of oil
pump housing.

CYLINDER BLOCK


If the measured value exceeds the limit, correct or replace crankshaft.

If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select the main bearing or connecting rod bearing. Refer to EM-253, "
MAIN BEARING OIL CLEARANCE"
and/or EM-252, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block onto surface plate to support main journal at both
ends of crankshaft.

Position dial indicator vertically onto No. 3 journal.

Rotate crankshaft to read needle movement on dial indicator
(total indicator reading).

If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Measurement

Install connecting rod bearings to connecting rod and cap, and
tighten connecting nuts to the specified torque. Refer to EM-235,
"ASSEMBLY" . Use inside micrometer to measure connecting
rod bearing inner diameter.
(Bearing oil clearance) = (Connecting rod bearing inner diame-
ter) − (Crankshaft pin journal diameter)

If clearance exceeds the standard, select proper connecting rod
bearing according to connecting rod big end diameter and
crankshaft pin journal diameter to obtain specified bearing oil
clearance. Refer to EM-242, "
HOW TO SELECT CONNECTING
ROD BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil, dust completely from
crankshaft pin journal and each bearing surface.

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

Install connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque. Refer to EM-235, "
ASSEMBLY"
for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod caps and bearings, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.Standard : 0.05 mm (0.0020 in)
Limit : 0.10 mm (0.0039 in)

MAIN BEARING OIL CLEARANCE
Method by Measurement

Install main bearings to cylinder block and bearing cap, and
tighten the bolts to the specified torque. Refer to EM-235,
"ASSEMBLY" . Then, measure the inner diameter of main bear-
ings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft
main journal diameter)

If out of the standard, check main bearing housing inner diame-
ter and crankshaft main journal diameter, and select appropriate
main bearing to adjust clearance to specifications. Refer to EM-
244, "HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil and dust completely
from crankshaft main journal and each bearing surface.

Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.

Install main bearings and bearing cap and tighten to the speci-
fied torque. Refer to EM-235, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Do not rotate crankshaft.

Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.
CRUSH HEIGHT OF MAIN BEARING

When bearing cap is removed after being tightened to the speci-
fied torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-235, "
ASSEMBLY" .

If out of the standard, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-235,
"ASSEMBLY" .

If out of the standard, replace connecting rod bearings.Standard : 0.039 - 0.066 mm (0.0015 - 0.0026 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.
