Removal and Installation of Front Oil SealEBS01FBN
REMOVAL
1. Remove the following parts.

RH engine undercover

Drive belt; Refer to EM-140, "DRIVE BELTS" .

Crankshaft pulley; Refer to EM-198, "PRIMARY TIMING CHAIN" .
2. Remove front oil seal with a suitable tool.
CAUTION:
Be careful not to damage oil pump housing and crankshaft.
INSTALLATION
1. Apply new engine oil to new front oil seal joint surface and seal lip.
2. Install front oil seal so that each seal lip is oriented as shown in
the figure.

Using the suitable drift [62 mm (2.44 in) dia.], force fit the seal
until it hits the bottom.
CAUTION:
Do not touch lips of oil seal. Make sure seal surfaces are
free of foreign materials.
3. Install in the reverse order of removal.

PRIMARY TIMING CHAIN

9. Install slack guide.
10. Install chain tensioner.

Push the plunger of the chain tensioner. While keeping
plunger pressed down with a push pin, etc., install chain ten-
sioner.

After installation, pull out the push pin holding the plunger.
CAUTION:
Check again that the alignment marks on sprockets and the
colored alignment marks on timing chain are aligned.
11. Install front oil seal to oil pump housing.

Using the suitable drift [62 mm (2.44 in) dia.], force fit the seal
until it hits the bottom.
CAUTION:
Do not touch lips of oil seal. Make sure seal surfaces are
free of foreign materials.
12. Install power steering oil pump cover to oil pump housing.

Apply a continuous bead of liquid gasket with the tube presser
(special service tool: WS39930000) as shown in the figure.
Use Genuine Liquid Gasket or equivalent.

Apply liquid gasket on oil pump-side surface.
13. Install oil pump housing as follows:

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)
