FUEL INJECTOR AND FUEL TUBE
c. Align center to insert quick connector straight onto fuel tube.
d. Insert fuel tube into quick connector (1) until the top spool (B) on fuel tubes is inserted completely and the second level spool (C)
is positioned slightly below the quick connector bottom end.
CAUTION:
• Hold at position (A) as show n, when inserting the fuel
tube into the quick connector.
• Carefully align to center to avoid inclined insertion to pre-
vent damage to the O-ring inside the quick connector.
• Insert the fuel tube until you hear a “click” sound and
actually feel the engagement.
• To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
• Do not reuse O-ring.
e. Before clamping the fuel hose with the hose clamp, pull the quick connector hard by hand, holding at the
(A) position, as shown. Make sure it is completely engaged (connected) so that it does not come off of the
fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
f. Install quick connector cap (1) over fuel hose side (B) and fuel tube side (A).
NOTE:

5. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. • Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
178, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-179, "Work Procedure"
.
WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.

CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on
both ends of the crankshaft.
• Place a dial gauge (A) straight up on the No. 3 journal.
• While rotating the crankshaft, read the movement of the pointer on the dial gauge (A), the total indicator runout reading.
OIL CLEARANCE OF CONNECTING ROD BEARING
Method of Measurement
• Install the connecting rod bearings (2) to the connecting rod (3)
and the cap (1), and tighten the c onnecting rod bolts to the speci-
fied torque. Using a inside micrometer measure the inner diameter
of connecting rod bearing (B).
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
• If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing. Refer
to EM-105, "How to Select Piston and Bearing"
.
Method of Using Plastigage
• Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
• Install the connecting rod bearings to the connecting rod cap, and tighten the connecting rod bolts to the specified torque.
CAUTION:
Do not rotate the crankshaft.
• Remove the connecting rod cap 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.
OIL CLEARANCE OF MAIN BEARING
Method of Measurement
• Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main beari ng) – (Outer diameter of crankshaft journal)
• If the measured value exceeds the limit, select main bearings referring to the main bearing inner diameter
and crankshaft journal outer diameter, so that t he oil clearance satisfies the standard. Refer to EM-105,
"How to Select Piston and Bearing".

CYLINDER BLOCK
Method of Using Plastigage
• Remove oil and dust on the crankshaft journal and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
• Tighten the main bearing bolts to the specified torque. CAUTION:
Do not rotate the crankshaft.
• Remove the bearing cap 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".
CRUSH HEIGHT OF MAIN BEARING
• When the bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude.
• If the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK BOLT
• Perform only with M10 (0.39 in) bolts.
• Measure outer diameters (d1, d2) at two positions as shown.
• Measure d2 at a point within area (A) as shown.
• When the value of d1- d2 exceeds the limit (a large difference in dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
• Measure outer diameter (d) at position as shown.
• When (d) exceeds the limit (when it becomes thinner), replace the
bolt with a new one.

< PRECAUTION >[VQ35DE]
PRECAUTIONS
• When tightening nuts and bolts, 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 specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or 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 after draining coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage.
Parts Requiring Angular TighteningINFOID:0000000009460520
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)
• 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.
Precaution for Liquid GasketINFOID:0000000009460521
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemi cal Products and Sealants"
.
