Installation
NOTE
• Use new bearing cap No.1 bolts. They are
deformed once they are used because they
are plastic deformation tightening bolts.
• All parts to be installed must be perfectly
clean.
• Be sure to oil crankshaft journals, journal
bearings, thrust bearings, crankpins,
connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps,
connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.

1) Install sensor plate (1) to crankshaft (2) and tighten
bolts to specified torque.
NOTE
When installing sensor plate, align spring pin
(3) on crankshaft and hole of sensor plate.

Tightening torque
Sensor plate bolt (a): 11 N·m (1.1 kgf-m, 8.0 lb-ft)2) Install main bearings to cylinder block.
Upper half of bearing (1), has an oil groove (2).
Install it to cylinder block (3), and the other half
without oil groove to bearing cap.
Make sure that two halves are painted in the same
color.
3) Confirm that dowel pins (1) are installed to intake
side of each journal.
4) Install crankshaft to cylinder block.
5) Install thrust bearings (1) to cylinder block between
No.2 and No.3 cylinders. Face oil groove (2) sides to
crank webs.

General Description
Fuel System DescriptionS6RW0D1701001
CAUTION!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.

The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator), fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System
Diagram”.
Fuel Delivery System DescriptionS6RW0D1701002
The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in fuel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System
Diagram”.
Fuel Pump DescriptionS6RW0D1701003
The fuel pump (1) is an in-tank type electric pump.
Incorporated in the pump assembly are;
a fuel filter (2), a fuel pressure regulator (3) and a fuel
level sensor (gauge) (4).

Fuel Pressure InspectionS6RW0D1704001
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk of fire and
personal injury.

1) Relieve fuel pressure in fuel feed line referring to
“Fuel Pressure Relief Procedure”.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel feed
hose (1) and fuel delivery pipe as shown in figure,
and clamp hoses securely in order to ensure that no
leaks occur during checking.

Installation
CAUTION!
• When connecting joint, clean outside
surfaces of pipe where joint is to be
inserted, push joint into pipe till joint lock
clicks and check to ensure that pipes are
connected securely, or fuel leak may
occur.
• Never let the fuel hoses touch the ABS
sensor harness (if equipped).

1) If parts have been removed from fuel tank, install
them before installing fuel tank to vehicle.
2) Raise fuel tank (1) with jack (2) and connect fuel
pump connector (3), ground wire (4) and clamp wire
harness.

filler neck (3) as shown in figure, and clamp them
securely.
Tightening torque
Fuel filler hose clamp (a): 1.5 N·m (0.15 kgf-m,
1.0 lb-ft)
5) Connect fuel feed hose (1) and vapor hose (2) to
each pipe as shown in figure, and clamp them
securely.
6) Install exhaust center pipe referring to “Exhaust Pipe
and Muffler Removal and Installation in Section 1K”.
7) Install propeller shaft (For 4WD model) referring to
“Propeller Shaft Assembly Removal and Installation
in Section 3D”.
8) Connect negative cable at battery.
9) With engine OFF, turn ignition switch to ON position
and check for fuel leaks.
Fuel Tank InspectionS6RW0D1706012
After removing fuel tank, check hoses and pipes
connected to fuel tank for leaks, loose connections,
deterioration or damage. Also check fuel pump
assembly gaskets for leaks, visually inspect fuel tank for
leaks and damage.
Replace any damaged or malconditioned parts.
