CRANKSHAFT PIN JOURNAL DIAMETER

Measure outer diameter of crankshaft pin journal with microme-
ter.

If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-251,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.

Out-of-round is indicated by the difference in the dimensions
between “X” and “Y” at “A” and “B”.

Taper is indicated by the difference in the dimensions between
“A” and “B” at “X” and “Y”.

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 main bearing and/or connecting rod bearing. Refer to EM-252, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-251, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block on precise flat table, and support the journals on
the both end of crankshaft.

Place dial indicator straight up on the No. 3 journal.

While rotating crankshaft, read the movement of the pointer on
dial indicator. (Total indicator reading)

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

Install connecting rod bearings to connecting rod and connect-
ing rod bearing cap, and tighten connecting rod nuts (VQ23DE)
or connecting rod bolts (VQ35DE) to the specified torque. Refer
to EM-233, "
ASSEMBLY" for the tightening procedure.

Measure the inner diameter of connecting rod bearing with
inside micrometer.

If calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod big
end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-241, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

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

Cut 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 connecting rod bearing cap, and tighten connecting
rod nuts (VQ23DE) or connecting rod bolts (VQ35DE) to the specified torque. Refer to EM-233, "
ASSEM-
BLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod bearing cap and bearing, and using
scale on 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 main bearing caps,
and tighten main bearing cap bolts with main bearing beam
(VQ35DE) to the specified torque. Refer to EM-233, "
ASSEM-
BLY" for the tightening procedure.

Measure the inner diameter of main bearing with bore gauge.
(Bearing clearance) = (Main bearing inner diameter) – (Crankshaft
main journal diameter)

If calculated value exceeds the limit, select proper main bearing according to main bearing inner diameter
and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-242,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

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

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

NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
CRUSH HEIGHT OF MAIN BEARING

When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-233, "
ASSEMBLY" for the tight-
ening procedure.

If the standard is not met, 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-233,
"ASSEMBLY" for the tightening procedure.

If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER

Measure outer diameters (“d1 ”, “d2 ”) at two positions as shown
in the figure.

If reduction appears in “A” range, regard it as “d2 ”.

If it exceeds the limit (large difference in dimensions), replace
main bearing cap bolt with new one.

EXHAUST SYSTEM


When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.

Temporarily tighten mounting nuts and bolts on the exhaust manifold side, and mounting bolts
and nuts on the vehicle side. Check each part for unusual interference, and then tighten them to
the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
Seal Bearing (QR20DE)
1. Securely insert seal bearing into exhaust manifold and three
way catalyst assembly side in the direction as shown in the fig-
ure.
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring large diameter side facing to exhaust front tube
flange, tighten mounting nut.
3. Make sure that stud bolt does not interfere with flange of
exhaust front tube.
INSPECTION AFTER INSTALLATION

Make sure that clearance between tail tube and rear bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Make sure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
