TIGHTENING TORQUE OF STANDARD BOLTSPFP:00000
DescriptionEAS001HU
This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differ-
ences between these two types of bolts/nuts; shape of the head, grade of strength, hexagonal width across
flats and the standard tightening torque.

For guidance in discriminating, refer to GI-41, "Tightening Torque Table (New Standard Included)" .

The new standard machine screws and tapping screws have a head of ISO standard torx recess.

If the tightening torque is not described in the description or figure, refer to GI-41, "Tightening Torque
Table (New Standard Included)" .
*ISO: International Organization for Standardization
Tightening Torque Table (New Standard Included)EAS001HV
CAUTION:

The special parts are excluded.

The bolts/nuts in these tables have a strength (discrimination) number/symbol assigned to the
head or the like. As to the relation between the strength grade in these tables and the strength
(discrimination) number/symbol, refer to “DISCRIMINATION OF BOLTS AND NUTS”.

CAUTION:
The parts with aluminum or the cast iron washer surface/screw surface are excluded.

lation to check its installed condition.
8. Install valve lifter.
9. Install spark plug tube if removed.

Press-fit it into cylinder head with the following procedure:
a. Remove old thread locking sealant from cylinder head side
installation hole.
b. Apply thread locking sealant all round on spark plug tube within
approximately 12 mm (0.47 in) width from edge of spark plug
tube on the press-fit side.

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-94, "
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-94, "
ASSEMBLY" for the tightening procedure.

Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)

If clearance exceeds the limit, select proper main bearing
according to main bearing inner diameter and crankshaft main journal diameter to obtain specified bearing
oil clearance. Refer to EM-102, "
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
oil holes.

Install main bearings to cylinder block and lower cylinder block, and tighten lower cylinder block mounting
bolts to the specified torque. Refer to EM-94, "
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.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.

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)

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)
